CLI :: Trying To Hide Then Show Main WinForm
Jun 18, 2014I have a main WinForm that I want to press a hotkey and show and hide the form. I can press Insert and hide the form and I see its icon in my Win7 task bar but when I press Insert again it doesn't show. Is my coding logic wrong to make it work? Maybe when its hidden the Insert key isn't being 'seen'? Although the code I am using I got somewhere on the internet that says it will work at the app level.
virtual bool PreFilterMessage(Message% m) {
// Detect key down messages.
if (m.Msg == WM_KEYDOWN) {
Keys keyCode = (Keys)((int)m.WParam) & Keys::KeyCode;

C# :: Swapping Multi Usercontrol In 1 Winform?
Jul 29, 2014So basically, I started out with each wizard == 1 winform, but then I found another way to do it by making the content of each wizard step a user control, then say, on initial deployment, it load usercontrol1, then when i click next, the panel hide usercontrol1 for usercontrol2 and so forth. Would it be feasible to create all usercontrols (all the wizard step) and add them in an array, then i can load them by index?

Nov 12, 2014So I am upgrading the system from 3.5 .NET to 4.5.1 and fixing any bug that I could find. Long story short, I run into an issue that basically tell me it couldn't find the images in the resource file. I figured out a work around, but first I have to set the picture box or background Image in design time to none. I ran into this Properties Windows while changing the value of picturebox for my user control saying: Property value is not valid. Object reference not set to an instance of an object. This usercontrol is taken from another user control from a different project. Basically, we are reusing it.

Visual C++ :: Switch From TXT To RTF During Runtime
May 2, 2015While running a Doc/View SDI, is there any way to switch from text mode to rtf mode during runtime? Search reveals nothing.
Say I have an editor and I want the app to use text, I can set the ctor as follows.
Code:
CEditorDoc::CEditorDoc() {
// TODO: add one-time construction code here
m_bRTF = FALSE;
}
But once I've done that and compiled the app, while it's running, is there a way for the user (or programmer) to change the mode back to RTF? One solution that occurred to me is to use 2 document classes, but that's a hassle.

C++ :: Processing Buttons Created At Runtime
Oct 7, 2014I am developing a small game using MFC in which the game options like new game, save, open, exit etc. can be selected from the menu as well as from the buttons inside the window. I have no problems with the menu but the buttons do not seem to work at all.
The buttons are created at runtime using CButton class. To associate the buttons with the corresponding functions, I just used the same resource ID for the buttons as the menu options, but that did not work. When I click on the buttons, nothing happens. If I assign different resource IDs to the buttons, how do I handle the message map entries? Do I have to write different message map entries for the menus and the buttons while their function is exactly the same?
C++ :: Oracle Library Runtime Error
Jan 14, 2014I downloaded Oracle instantclient-basic-nt-12.1.0.1.0.zip and instantclient-sdk-nt-12.1.0.1.0.zip and extracted both to c:oracle I then went into visual studio 2013 and created a Win32 Console application with all default parms.
I then went into project -> properties -> C/C++ -> General -> Additional Include Directories and added my include path C:oraclesdkinclude
I then went into project -> properties -> Linker -> General -> Additional Library Directories and added C:oraclesdklibmsvcvc11
I then went into project -> properties -> Linker -> Input -> Additional Dependancies and added oraocci12.lib
The program compiles but when I debug i get a RUNTIME error that says "The program can't start because oraocci12.dll is missing from your computer. Try reinstalling the program to fix this problem. But I know the file exists in C:oraclesdklibmsvcvc11oraocci12.lib
This is the code if it makes a difference

C++ :: Manipulate Image File At Runtime
Oct 20, 2013I've come to a point where I want to manipulate an image file at run time or with pre-determine sizes and have to be applied when the windows is moved or through in program options.
I know I can do the applying part. However I am a little unsure of how to tackle the image manipulation. I want to make it so that it is not os dependant. So I know I can not rely on any os functions. The only other thought that came to mind was to deal with the video card itself.
So the main question after all of that is said and done. How is c++ able to interact with the video card directly for images? Or if there are existing function I can use. How do they do that? If I can use existing function I would like to be able to manipulate it myself.

It is either happening in insert(const &string s) or in the implementation of vector<list<string>> ht. I would appreciate some input. This is the implementation of insert():
void HTable::insert(const string &s) {

View 12 Replies View RelatedC/C++ :: How To Initialize Array Of Structures At Runtime
Aug 26, 2014I somewhere read "You cannot initialize a structure like that at run time."
Example:
struct item_info {
char itemname[15];
int quantity;
float retail;
float wholesale;
[Code] ....
But if you want to assign values at run time then you have to do it manually like:
strcpy(item[0].itemname, "rice");
item[0].quantity = 10;
item[0].retail = 40;
item[0].wholesale = 30;
I tried in internet but am unable to know the differences. I want to know the difference between those two in terms of run time and compile time. Explanation required also for below one. Is this run time or compile time? How does we actually decide which is run time and which is compile time!
struct item_info {
char itemname[15];
int quantity;

C++ :: Declaring Variables (Conditional) At Runtime?
Jan 22, 2014I am looking for a way to declare variables at run time which being a static language shouldn't happen. I will explain my situation.
I am upgrading a legacy program that modifies executables (non malicious). I am trying to add 64bit support.
It is a huge project and I understand the majority of it but my issues with how it handles the input data.
It has a struct that certain parameters of the input file is loaded into:
Code:
typedef struct DATA {
DWORD Size;
IMAGE_NT_HEADERS32 Headers;
} _DATA; *PDATA
etc, etc its a huge list.
My problem lies in the fact that I need to change IMAGE_NT_HEADERS_32 to IMAGE_NT_HEADERS64 at runtime.
That DATA struct gets called at least 110 times during runtime.
How I might tackle this? Having a conditional statement repeated that many times seems ridiculous.
