C# :: Get Location Of ToolStripButton Image?
Mar 14, 2015
How can i get the Location of an Image used by the ToolStripButton? I need the locaton to detect if the cursor is above the image that i use for the button. I tried it like this:
private void ToolStripButton_MouseHover(object sender, EventArgs e) {
Graphics formGraphics = this.CreateGraphics();
GraphicsUnit graphicsUnit = GraphicsUnit.Point;
RectangleF imageBoundsF = reloadToolStripButton.Image.GetBounds(ref graphicsUnit);
[code].....
The problem is that i have the width and the height but the location is always 0 or x and y are always 0, so how can i do it?

Im trying to compare the image of a button to another image in Visual Studio like so...
//variables
Image active = Image.FromFile("C:\Users\Ethan\Desktop\StarWars Status\active.png");
Image stunned = Image.FromFile("C:\Users\Ethan\Desktop\StarWars Status\stunned.png");
[Code]...
btnStatusPlr1.Image SHOULD come back as True.Then I realized it might not be the same as setting the buttons image in the properties (Which is what i did to get the original image (the one being compared to))
I do have a feeling ive done something wrong here (Yes im a noob /> )
Variable active, is the same image as the buttons default (Well should be)

In the code below. I believe I am returning the memory location of the value I am looking for. How can get the value?
main.cpp
int choice = 0;
PlayerMenu *newPM = new PlayerMenu;
File *file = new File;
// Menu for loading, creating or exiting the game
choice = newPM->menuChoices();
PlayerMenu.cpp
[Code] ....
I am not sure how to deference the value so I can get at the value instead of the memory location.

Here's my code, my problem is that it is not sending the keystrokes to the LOG.TXT file I want them to be going to.
1 #include <iostream>
2 using namespace std;
3 #include <windows.h>
4 #include <winuser.h>
5 #include <stdio.h>
6 int save (int key_stroke, char *file);

Any difference between
Code:
class SomeOtherClass;
void foo(SomeOtherClass* p);
And
Code:
void foo(class SomeOtherClass* p);
I was told that "2" would limit the scope of the forward declaration to the declaration of foo... However, after testing it, it appears that both behave the same...

I recently started learning C++ and wanted to deep a bit into process memory reading for Windows, but I get an error I don't know how to fix. I'm using Visual Studio Express 2013 as my IDE and it tells me this, when I try to run and debug:
"Unhandled exception at 0x77E3E243 (ntdll.dll) in readProcessMemory.exe: 0xC0000005: Access violation reading location 0x00000043."
The Call Stack window says following:
ntdll.dll!_NtRaiseException@12() Unknown
ntdll.dll!_KiUserExceptionDispatcher@8() Unknown
ntdll.dll!_RtlInitUnicodeString@8() Unknown
> readProcessMemory.exe!main() Line 8 C++
[External Code]
And in the Output window is this: First-chance exception at 0x77E3E243 (ntdll.dll) in readProcessMemory.exe: 0xC0000005: Access violation reading location 0x00000043. Unhandled exception at 0x77E3E243 (ntdll.dll) in readProcessMemory.exe: 0xC0000005: Access violation reading location 0x00000043.
My code should be extremely simple, I'm just trying to find a Windows window. But here's the code.
Code:
#include <windows.h>
#include <iostream>
using namespace std;
int main(){

I have my libraries in ../../lib location
and when i try to compile :
gcc -O9 -I ../../include/ -L ../../lib/ -o test test.c thr.o -lm -lthread
I get :
gcc: error: thr.o: No such file or directory
obviously the problem is the library path location but my obj is there

I have a 3d Point in space. From this point I have vertices defind by(scale). I have a Quaternion representing the rotation of the object (lets say a block). So...
(1) I know the point in local and world space and can translate.
(2) I know the scale of the object and it's starting vertices intersections at zero rotation.
(3) I have the quaternion which represents the 3d rotation and can translate that to degrees and Eulers.
How do i find the exact points of the vertices after the rotation. (what I'm attempting to do is plot points from vertice to vertice all along the sides/top/bottom of the object.)I have looked at Matrix4 transformations and Quaternions and still do not understand how to find the vertices after rotation.

I have these two functions listed below. DoEvent() gets called from a window procedure whenever some event occurs. SetEvent() sets an element of the m_Events array a pointer to a Command object to handle the event. The array is zeroed in the constructor.
The error occurs on line 16 in the code in DoEvent(). Why the array is suddenly unreadable. When I call SetEvent() it works just fine, no problem.
When I step through the debugger in SetEvent i see that each element begins as 0 and the element I set is set properly. However, when I step through DoEvent() all elements in m_Events show "?????" "Unable to read memory".
uw::Command* uw::WindowBase::SetEvent(uw::WindowEventsEnum event, uw::Command* command) {
if (event < 0 || event >= FINAL_EVENT_ENTRY)
return NULL;
Command* ret = m_Events[event];
m_Events[event] = command;
return ret;

I already wrote:
strncpy(buff2, buff1[i], strlen(buff1)-i );
but this function seem to just copy from the beginning of a buffer to another, not from the ith element.Is there such a function?
Buff1&buff2 are char[10000] and i is declared int, holding the interesting element's position.

I know how to find the occurrences of a character in a string, but I have a more specific problem.
For example, consider the string:
" C 1.3825 4.0000 12.0000 1.9133 0.1853 0.9000 -1.1359 4.0000 "
I want to extract a vector that contains the positions of every first character for each number.
For the example above, the output should be a vector with elements [6 15 23 33 etc...]. These are the positions of the first character for every number.
I need to be able to do this for any arbitrary string with any arbitrary amount of numbers and characters in it (I also need to account for negative numbers).

Right now my application database is stored in the AppDataRoamingAppName directory.
The client has requested that the administrator choose the location for the database, and have a choice between a local machine, or an online repository.
The clients are not IT people, they are business people, and I don't think it's a good idea to let a user choose where to keep the central app database. Other users (think admin vs user) will need to download the database for use on their own local machines, which is how the issue even came up, it's kind of a shared database that only the admin can add to.
My compromise was to COPY the main database to the location of the user's choosing, then push updates to it as the main database was written to.
So after working on this today, I have the user choose a directory, I add the file path to the application settings, then I create the file and copy the database as needed to the new location (online repositories are next).

I have a std::vector of short ints that I need to write to a specific location in a binary file (without using .NET code). To that end, I wrote up this code:
Code:
ofstream fileStream (filePathString, ios::out | ios::binary);
int curPos = 2821;
fileStream.seekp(curPos);
int iter = 0;
while (iter < 1024*1024){
char bytesToWrite[2];
//Low byte
bytesToWrite[0] = LOBYTE(dataVector[iter]);
[Code]...
The code runs without crashing, but when I look at the file afterwards in a hex editor, every byte (even those outside the range I thought I was writing to) are replaced with 00. I suspect I'm missing something in my understanding of file streams. Did I write that code correctly? Seekp does move the pointer over the next byte to be overwritten, yes? Am I getting a memory leak somewhere?

I just started deal with pointers in C, and one stuff confusing me...
Here is simple code:
int main (){
int var1 = 10;
int var2 = 20;
long ms = 10000000;
printf("Address of var1 variable: %p
", &var1 );
[Code] ...
But - when I run pmap - I don't see this addresses there:
Code:
# pmap -x 16496
16496: ./address
Address Kbytes RSS Dirty Mode Mapping
0000000000400000 4 4 0 r-x-- address
0000000000600000 4 4 4 rw--- address
00007f79cf8b8000 1576 260 0 r-x-- libc-2.12.so
00007f79cfa42000 2048 0 0 ----- libc-2.12.so
00007f79cfc42000 16 16 16 r---- libc-2.12.so
I guess - it's is inside stack:
Code:
# cat /proc/16496/maps | grep stack
7fff0d7e5000-7fff0d7fa000 rw-p 00000000 00:00 0 [stack]
But - how I can obtain this variables addreses, to see them with `pmap`? If I put them as "global":
Code: ...
#include <stdlib.h>
#include <sys/types.h>
int var1 = 10;
int var2 = 20;
int millisleep(unsigned ms);
int retpid(void);
[Code] ......
I have odd addresses in result:
Code:
Address of var1 variable: 0x600a94
Address of var2 variable: 0x600a98

I'm trying to make it possible to have a 2 dimensional linked list with syntax like with vectors:
List<List<std::string>> words(5, List<std::string>(5, "Hello"));
I coded everything so that this kind of syntax would be possible, but now, when I execute my program, I get the following error:

All my code is good, except the functions: findMacLoc and findMinLoc .They don't give me the correct array location of the max/min number in the array.I know is something simple I need to tweak in those two functions.
#include <iostream>
#include <time.h>
using namespace std;
void printArray(int a [], int & size)
{
int i;
for (i = 0; i < size; i++)

Under Microsoft, I use GlobalAlloc and GlobalFree to dynamically allocate and free memory. Intermittently GlobalFree is reporting error 998 (GetLastError() - Invalid access to memory location). I've checked my logs of addresses returned by GlobalAlloc against those being freed by GlobalFree and when the problem occurs the address causing the error has been allocated by GlobalAlloc and has not been freed before since allocation.
I can't reproduce it. Currently I'm checking for error 998 from GlobalFree and ignoring it if it occurs - which is not satisfactory. I have one function (AllocMem) that calls GlobalAlloc and checks for errors and another function (FreeMem) which calls GlobalFree and checks for errors.
My program uses AllocMem and FreeMem everywhere memory is required or freed. AllocMem and FreeMem are in a DLL. The program is heavily threaded and a different thread may call AllocMem to the one that calls FreeMem. I don't believe I've got a race condition etc as all the code in the program containing the AllocMem and FreeMem calls are part of a CriticalSection using the same variable.
What is a possible cause of this error?

I'm doing a card game and i'm unclear on how to retrieve the card by doing vectors. after i use use srand() in main and create a rand() in a function, how can i retrieve that random card 1-52?
so far i know that i have to find the length of the card. but i don't know why i have to save the location onto another variable and erase the card of the specified index before returning the card out the function.
int location = rand() % cards.size();
I don't know why i need to do this and how do i reinitialize the variable cards into another variable?

My project is to get a file from a designated location in my computer and not just read, but grab the values from the user and make a count, sum, and average calculation of the numbers in my code. I am using the fstream library and I am trying I did do it, I got the values and calcualated them, however I want the values to be accessed from maybe my desktop or my drive, I want to know how to manipulate my code to get a path like C:UserDesktop and maybe executed from the path input or given. I dont know if this is possible, or easy to do. ALso I did copy some of this code from my teachers examples and I dont know exatly why the variables have to be initilized at zero, and I would like to know a little more on the Bitwise right shift breaker used in line 20 something.
Here is my code below.
#include <iostream>//For avergae functionality
#include <fstream>//For the file commands, such as ifstream and the Bitwise right breakers(<< and >>).
#include <iomanip> // To control the amount of decimals in my results desired.
using namespace std;
int main () {
int aNumber=0; //Initilized at zero because of Stack Overflow:

I have a contiguous sequence of section headers in a file (all the data in the file is stored in void * data), where each section header is the same size and has the same fields in the same order. So it's laid out like an array.
I have to:
- Use an offset value and the number of section headers variables to identify the location and length of the section header table (these are hdr.offset and hdr.length respectively).
- The offset value shows the distance between the start of the file and the start of the first section header (so I need a pointer to the start of the first section header)
- Apply a typecast to location of the section header table to process it as an array of section headers.
Here is what I have done, but I am getting a segmentation fault. What am I doing wrong? How do I fix this?
typedef struct {
unsigned int name;
unsigned int type;
} SectionHeader;

How do you programmatically expand a url link to its true location?
Do you know about tinyurl.com and baidu.com? Baidu.com is a search engine that tries to discourage people from using their web site to make metasearch engines by hiding their links in a way that is a lot like how tinyurl.com works. TinyUrl.com is a web site where, if you want to present someone with a link to something and that link is long, you can use tinyurl to produce a tiny url for presentation purposes.
Anyway, what I want to do is to find a way to programmatically take the link [URL] (the first link in a search for Jessica Alba using baidu.com) and have it return the actual link, [URL] . That is just one example. What I want to do is not specific to Jessica but for using Baidu.com as part of my group of search engines in my meta search eneing project.
Maybe there is a way of using the WebBrowser class but I did not see a member that was the URL.
Maybe there is a way of using WebRequest and WebResponse.
