C++ :: How To Manage Popup Windows
Mar 24, 2014
I’m working on a project that has many pop up windows. They are not organized properly and things are getting messy. I’m wondering if there are any common practice or design patterns for solving this problem.
I’d like to give some concrete examples:
1. my program connects to two different tcp ports on the same ip. cutting off any of them, the user will be notified with a MessageBox. But in case of unplugging network cable, both message box will show, which is unnecessary.
2. we provide a shortcut key to display a setting dialog. However the program can also show the same dialog when certain event happens. If the user opens the setting dialog already, those event will still trigger a second setting dialog.
3. when application settings are not correct, user will disconnect from the server and an error dialog will show up and terminate the program. But if the user knows about the situation and has opened the setting dialog to fix the issue, the error dialog will terminate his work. which is bad.
I don’t know how to deal with this window management problem in a complex software project. Of course, I can solve the issue case by case by checking if certain dialog is shown before displaying another dialog. But there are too many cases, when the code base gets big, this is not practical. There must be some generic solution I think.

I create new dialog window. I add container Fixes and change Fixed properties : - AutoSize, +Expand, +Fill to enable other widgets. I add Text View, Textview is inside GtkScrolledWindow which has property X and Y but not Height and Width. If GtkScrolledWindow has scrollbars, its size is fixed, if not - size depends on the content Textview and grows when I type text. I want not to grow control if I type Text but want my own size. It is possible?

I wrote a class to manage pointers better (because I am making a large program and don't want to call a constructor on somthing that was already deleted... etc...), but I am getting some compiler errors. I'm not sure what to do.
here is the class prototype:
template<typename type>
class pointer_class{
public:
pointer_class() : dat(NULL), del(false) {}
explicit pointer_class(const pointer_class<type>& d) : dat(NULL),
[Code].....

I wrote a class pedal that allows to search for the serial port on which the pedal is connected. Therefore I send a request to the pedal and set up a timer event of 20 ms. If no reply, I search for the next serial port.
When found I send configuration to the pedal and set another timer event of 200 ms that requests for pedal state. It runs fine.
Now if the pedal is disconnected then connected again I would like it to run again.
Therefore I set another timer event every 2s that launches all what I described above.
The trouble comes because the 20 ms timer event doesn't run and I do not understand why.

I have a POPUP
MAIN_MENU MENU {
POPUP "&Manager" {
MENUITEM "New Royal Python", MENU_NEW_ROYAL_PYTHON
POPUP "&Select Python" {
}
}
}
I basically want to give the POPUP an ID so I can talk with it but it does not seem to be accepting a second parameter. Once I have done that I need to send a message to it to ask it to add a new item, what are the messages I need to send for this?

Our teacher wants us to make a timeline showing a picture from each year of our lives. I thought of a creative way of doing this in c++, make the user input the year they want to see, then make the image popup on the screen. Is this possible and how would I go about doing this? Here is the code I have so far:
#include <iostream>
using namespace std;
int main() {
int userInput;
cout << "Hello and welcome to my timeline!" << endl;
cout << "Please type in what year you would like to see and press enter" << endl;

recently I developed a class header only in C++ to deal with byte arrays. Since I developed programs in other languages that had some libraries to dial with byte arrays, I developed one that the syntax is very similar to other languages.
Since I'm not very familiar with memory management, I was concerned about somethings I've read about (ex: memory fragmentation).
Here is a very simple example of my practice:
class ByteArray {
public:
ByteArray(size_t size) {
buffer = (int8_t*)malloc(size);
}
[Code].....
The class is intended to be used as part of comunication protocol in a webserver, byte arrays are created and destroyed a lot. Should I use pools? Is there a better practice? Am I doing everything wrong (laugh)?
For those who wants to see the entire class: [URL]

I am creating a website in which a user can upload an image to a sql database. It is converted to varbinary and then read into an Image object using a http handler to convert it to an image. this all works fine. When I open an popup window I am reading data from specific rows into textboxes, thus when the user confirms any changes the rest of the data stays the same. How can I hold the Image and redisplay it when returning to the main page after closing the pop up. It currently sets the image in the database to null as the file upload object has not been given a directory location all the time. This is my attempt at reading the image from the database and then reapplying it if the file upload is empty
private void ChangeFilm(int id)
{
SqlConnection con = new SqlConnection(my settings go here);
con.Open();

I want to select text entered in a popup and save it. I have a form that contains a text area and a button
<asp:TextBox ID="TextBox1" runat="server" TextMode="MultiLine" Height="103px" Width="262px"></asp:TextBox>
<br />
<br />
<asp:button runat="server" text="Add" onclick="Unnamed1_Click" />
when we click on a line in text area I want to open a popup having all text from that line. I should be able to select some of its text then if I click on save button of popup then only selected text should be saved and displayed in original text area of form. I want to use this for multiple sentences of text area.
Add button will add new line.

I was reading a c++ code written in embarcadero ide to add vertical colour text in popup menu.
While reading the code, I had seen following instructions.
private:
Code:
void __fastcall ExpandMenuItemWidth(TObject *Sender, TCanvas *ACanvas,int &Width, int &Height);
Code:
void __fastcall DrawNewItem(TObject *Sender, TCanvas *ACanvas, const TRect &ARect, bool Selected);
The above two methods used in the code like below:
Code:
PopupMenu1->Items->Items[i]->OnMeasureItem = ExpandMenuItemWidth;
PopupMenu1->Items->Items[i]->OnDrawItem = DrawNewItem;
What is happening when we are using member function without parameters like above?
I found above code at: [URL] ....

Here are the libraries included:
#include <iostream>
#include <cmath>
#include <cstdlib>
#include "stat.h"
And heres the line being flagged:
d=ttl*drand48()-fit[0]; //intialize to reigon for first entry
The error I receive is one discussed on a number of different forums:
C:Documents and SettingssarabrownDesktopSarahScheduling Codestat.cpp|181|error: `drand48' undeclared (first use this function)|
C:Documents and SettingssarabrownDesktopSarahScheduling Codestat.cpp|181|error: (Each undeclared identifier is reported only once for each function it appears in.)|
||=== Build finished: 2 errors, 1 warnings ===|
It just seems to me theres a lot of conflicting information about if this is even possible to do on Windows and when I do try work around functions or calling double drand(void) I get a ton of errors. I'm hesitant to try rand() or something less precise. I was hoping maybe someone would be able to maybe suggest a compiler which will run this or a different library, right now I'm using Code Blocks IDE.

Basically I want to embed the QGIS canvas widget into a custom application. In order to do that, I need to build QGIS from it's source in order to obtain the devel *.lib, *.dll, *.h, etc. files required. To that result, I am trying to build either version 2.6.* or the current nightly build ~2.7 - 2.8 64 bit version. There is very little documentation on the x64 builds. Not to mention that CMake and I are not the best of friends.
My progress so far:
- Successfully built the extremely out of date nightly build readme instructions of version 0.11 x86
- Partial success in creating CMake output to VS2010, but many required headers were not included such as gqsmapcanvas.h, (So even if I got it building I couldn't use the canvas widget in an application)
*Note I updated the external packages to x64 versions, so it is not an architecture mismatch issue.
I have also had issues with QWT looking for QWT Polar header files, but I suspect this is another issue with the missing headers as most of the errors related to files contained in the original source from GIT.

I've just integrated the Windows SDK V7.0A into my VS2005 application, and I'm getting the dreaded "Application configuration error" when I try to run it on an XP machine.
It runs fine on the development machine, and some customer machines (Win7 and Win8), but will not run on XP due to missing/incorrect version dlls.
I've rebuilt all my libraries, but still no joy.
So, my first question is - If I upgrade the Windows SDK to V7.0A, do I also need to use MFC 10 and msvcrt10, or can I stick with MFC 8?
The next question is, how do I find out which dlls are missing, and which libraries or other dlls are requesting the missing versions?
