Hi,
In any case one form will be the parent of the other form. So in the 2nd form use the GetParent() function to get the pointer cast it to the parent parentclass, set the parent's values using the currently got value
Have a look @ the following code,
CParentDlg *pParent = (CParentDlg *) GetParent();
pParent->m_iNewValue = m_iGotValue;
Hope this will help you.

Your question is a little confusing, but I think you need to a forward declaration of one of your classes.
class Form1; in your Form2.h
or
class Form2; in your Form1.h
A lot depends on how the classes are referencing each other.

Hi
I am creating a class derived from CListBox so I can control the fonts, color, etc2. I also want to control the background color of the listbox (not the text's background color, but the whole listbox' background color), and I am doing it by handling WM_ERASEBKGND message in OnEraseBkgnd() function.
The OnEraseBkgnd() implementation is very simple, basically I just obtain the client rect and the use CDC::FillSolidRect to fill it with the background color of my choice.
The problem is, the background color is correctly drawn if there is at least one item in the listbox, but when the listbox is empty, the background color is always displayed as white, even though I have stepped in the debugger and make sure that the FillSolidRect function is executed.
Could someone tell me what the possible cause for this is? Thanks!

Hi
this is from MSDN :
<br />
The WM_CTLCOLORLISTBOX message is sent to the parent window of a list box before the system draws the list box. By responding to this message, the parent window can set the text and background colors of the list box by using the specified display device context handle.<br />
|
|
|
|

Are you calling the base class OnEraseBkgnd() ?

Hello, I'm creating a program that displays a menu to the user and gives the user the option to open the following programs:
1. Freecell
2. Minesweeper
3. Paint
4. Quit
It does open the programs correctly but when the user enters 4 for quit, I want my program to close all of the programs the user opened. I am not sure how to do that though. I have created a function called ExitProcess and have a call to it when the user enters 4 as their choice. There is no code in that function.
Here is most of the code:
#include <iostream.h><br />
#include <windows.h><br />
#include <string.h><br />
#include <stdio.h><br />
<br />
void DisplayMenu();<br />
void CreateProcess(int option);<br />
void ExitProcess(void);<br />
void main()<br />
{<br />
DisplayMenu();<br />
<br />
return;<br />
}<br />
<br />
void DisplayMenu()<br />
{<br />
int option;<br />
<br />
<br />
cout << "\n\nPlease type your choice "<br />
<< "and press the return key : ";<br />
<br />
cin >> option;<br />
CreateProcess(option);<br />
<br />
return;<br />
}<br />
<br />
void CreateProcess(int option)<br />
{<br />
STARTUPINFO si;<br />
PROCESS_INFORMATION pi; <br />
<br />
ZeroMemory( &si, sizeof(si) );<br />
si.cb = sizeof(si); <br />
ZeroMemory( &pi, sizeof(pi) ); <br />
<br />
switch (option)<br />
{<br />
case 1 : if( !CreateProcess( NULL, <br />
"C://FreeCell.exe",NULL,NULL,FALSE,NULL,NULL,NULL,&si,&pi)) <br />
{<br />
ExitProcess(1);<br />
} <br />
system("cls");<br />
DisplayMenu();<br />
<br />
break; <br />
<br />
case 2 : if( !CreateProcess( NULL, <br />
"winmine.exe",NULL,NULL,FALSE,NULL,NULL,NULL,&si,&pi)) <br />
{<br />
ExitProcess(1);<br />
} <br />
system("cls");<br />
DisplayMenu();<br />
<br />
break;<br />
<br />
case 3 : if( !CreateProcess( NULL, <br />

{<br />
ExitProcess(1);<br />
} <br />
<br />
system("cls");<br />
DisplayMenu();<br />
<br />
break;<br />
<br />
<br />
<br />
case 4 : WaitForSingleObject( pi.hProcess, INFINITE );<br />
ExitProcess();<br />
CloseHandle( pi.hProcess );<br />
CloseHandle( pi.hThread );<br />
<br />
exit(100);<br />
<br />

Enumerate All Windows on specified thread. Post WM_CLOSE to them , in order to close the application in safe manner.Later u may call terminateprocess API

Thanks for the reply.
I am getting an 3 errors which say "left of .cb must have class/struct/union type".
This is the part of the code it is giving those errors:
<br />
PROCESS_INFORMATION pi[3];
STARTUPINFO si[3];
ZeroMemory( &si[0], sizeof(si[0]) );<br />
ZeroMemory( &pi[0], sizeof(pi[0]) ); <br />
ZeroMemory( &si[1], sizeof(si[1]) );<br />
ZeroMemory( &pi[1], sizeof(pi[1]) ); <br />
ZeroMemory( &si[2], sizeof(si[2]) );<br />
|
|

|

Change the code like this:
PROCESS_INFORMATION pi[3];
STARTUPINFO si[3];
ZeroMemory( &si[0], sizeof(STARTUPINFO));<br />
si[0].cb = sizeof(STARTUPINFO); <br />
ZeroMemory( &pi[0], sizeof(PROCESS_INFORMATION)); <br />
ZeroMemory( &si[1], sizeof(STARTUPINFO));<br />
si[1].cb = sizeof(STARTUPINFO); <br />
ZeroMemory( &pi[1], sizeof(PROCESS_INFORMATION)); <br />
ZeroMemory( &si[2], sizeof(STARTUPINFO));<br />
si[2].cb = sizeof(STARTUPINFO); <br />
ZeroMemory( &pi[2], sizeof(PROCESS_INFORMATION));

I have configured the code as shown below: Including a couple of functions. The program builds with 0 errors and 0 warnings, but for some reason when I enter a choice like (1) for "Freecell", my program quits, the program that I have opened remains open, so I do not have the chance to quit the Freecell program. Not sure why it is not giving me another choice:

You should declare the arrays (si and pi) as global variables. Also you can't call the DisplayMenu from within the process function (recursion).
Here's an example how to fix these problems:
STARTUPINFO si[3];
PROCESS_INFORMATION pi[3];
int DisplayMenu();
void process(int option);
void main()
{
ZeroMemory( &si[0], sizeof(si[0]) );
si[0].cb = sizeof(si[0]);
ZeroMemory( &pi[0], sizeof(pi[0]) );
ZeroMemory( &si[1], sizeof(si[1]) );
si[1].cb = sizeof(si[1]);
ZeroMemory( &pi[1], sizeof(pi[1]) );
ZeroMemory( &si[2], sizeof(si[2]) );
si[2].cb = sizeof(si[2]);
ZeroMemory( &pi[2], sizeof(pi[2]) );
while(DisplayMenu()!=4)
return;
}
int DisplayMenu()
{
int option;
system("cls");
cout << "\n\n\n";
cout << "\n\t*********************************";
cout << "\n\t* *";
cout << "\n\t* MENU *";
cout << "\n\t* *";
cout << "\n\t* 1. FreeCell *";
cout << "\n\t* 2. MineSweeper *";
cout << "\n\t* 3. Paint *";
cout << "\n\t* 4. Quit *";
cout << "\n\t* *";
cout << "\n\t*********************************";
cout << "\n\nPlease type your choice "
<< "and press the return key : ";
cin >> option;
process(option);
return option;
}
void process(int option)
{
switch (option)
{
case 1 : if(pi[0].hProcess==NULL)CreateProcess( NULL,
"FreeCell.exe",
NULL,
NULL,
FALSE,
NULL,
NULL,
NULL,
&si[0],
&pi[0]);
break;
case 2 : if(pi[1].hProcess==NULL)CreateProcess( NULL,
"winmine.exe",
NULL,
NULL,
FALSE,
NULL,
NULL,
NULL,
&si[1],
&pi[1]);
break;
case 3 : if(pi[2].hProcess==NULL)CreateProcess( NULL,
"MsPaint.exe",
NULL,
NULL,
FALSE,
NULL,
NULL,
NULL,
&si[2],
&pi[2]);
break;
case 4 : if(pi[0].hProcess)::PostThreadMessage(pi[0].dwThreadId,WM_QUIT,0,0);
if(pi[1].hProcess)::PostThreadMessage(pi[1].dwThreadId,WM_QUIT,0,0);
if(pi[2].hProcess)::PostThreadMessage(pi[2].dwThreadId,WM_QUIT,0,0);
CloseHandle( pi[0].hProcess );
CloseHandle( pi[0].hThread );
CloseHandle( pi[1].hProcess );
CloseHandle( pi[1].hThread );
CloseHandle( pi[2].hProcess );
CloseHandle( pi[2].hThread );
break;
default : printf("\a\aOption Not Available\n");
break;
}
return;
}

Finally got it!
Thanks for all the help
|
|

|

Again thanks for the help Andrzej, I have pretty much configured the program to work how I want except for one thing.
I want to be able to open more than one of the same program. So if I open one Paint program I want to be able to enter 3 again for Paint and have it open another. It only lets me open one of each right now.
Is there anyway to work around it? Meaning can I keep the global variables or is that one of the things that is preventing me from opening more than one program?
Thanks again.
|
|
|
|
|
Just want to clarify something...
I know how to be able to open more than one program but I'm not sure how to let the computer keep track of them so it closes them all.
When I do change it to open more than one program and I enter 4 to close them it does not close any of them.

Very Important!!!!
Don't use WM_QUIT message to kill other processes. Instead of WM_QUIT use WM_CLOSE. If you send WM_QUIT the application will not clean up resources and you will have memory leaks.
Regards,
Andrzej Markowski
|
|
|
|
|
Posting WM_CLOSE message to the main thread using PostThreadMessage doesn't close your application also. You have to post WM_CLOSE message to all windows on the main thread, as vikrams said. Here's the code how to do this :
BOOL CALLBACK EnumThreadWndProc(HWND hwnd, LPARAM lParam)
{
::PostMessage(hwnd,WM_CLOSE,0,0);
return TRUE;
}
EnumThreadWindows(rp[option-1].dwThreadId,EnumThreadWndProc,0);Regards,

I´m trying to use the IDirectDrawSurface::AlphaBlt method in wince.
Then I have to create an alpha surface and blit that surface to a "normal" (not an alpha surface) surface with the AlphaBlt method, I think....
But when I try to create an alpha surface,I get an invalid parameter as a result!
Is there anybody that has a clue to this error?
These are important flags for the DDPIXELFORMAT in wince:
DDPF_ALPHA: The pixel format describes an alpha-only surface.
DDPF_ALPHAPIXELS: The surface has alpha channel information in the pixel format.
DDPF_ALPHAPREMULT: The color components in the pixel are premultiplied by the alpha value in the pixel. If this flag is set, the DDPF_ALPHAPIXELS flag must also be set. If this flag is not set but the DDPF_ALPHAPIXELS flag is set, the color components in the pixel format are not premultiplied by alpha. In this case, the color components must be multiplied by the alpha value at the time that an alpha-blending operation is performed.
DDPF_RGB: The RGB data in the pixel format structure is valid.
I think I should only use the DDPF_ALPHA and DDPF_RGB flags but I am not sure?
Any comments?
I don´t think I should specify any alphabitdepth as there is no alpha channel information in the RGB_565 pixelformat,isn´t that right?
This is how the code looks like:
Globals:
<br />
LPDIRECTDRAW4 lpDD4;<br />
LPDIRECTDRAWSURFACE4 lpddsurf;<br />
SIZE size;<br />
<br />
size.cx=486;<br />
size.cy=274;<br />
<br />

<br />

ddsd.dwWidth = lpSize->cx;<br />
ddsd.dwHeight = lpSize->cy;<br />
<br />
<br />
res=lpDD4->CreateSurface(&ddsd,lplpDDS,NULL);<br />
if(res!=DD_OK) <br />
MessageBox(NULL,L"CreateSurface didn´t worked",NULL,NULL);<br />
<br />
switch(res){<br />
case DDERR_INVALIDPARAMS:<br />
MessageBox(NULL,L"CreateSurface INVALIDPARAMS",NULL,NULL);<br />
break;<br />
case DDERR_INVALIDOBJECT:<br />
MessageBox(NULL,L"CreateSurface INVALIDOBJECT",NULL,NULL);<br />
break;<br />
case DDERR_SURFACEBUSY:<br />
MessageBox(NULL,L"CreateSurface SURFACEBUSY",NULL,NULL);<br />
break;<br />
}<br />
}<br />
<br />
return 0;<br />
}
Please help anyone, I cannot understand what is wrong, it has to be something with the flags?
Thanks for your help!

Hello,
I'm wondering if anyone has experienced the
"Windows cannot find <path>\<filename>. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search."
error when attempting to launch their MFC/C++ app. via double-clicking a file associated with the application. Oddly enough, the application will launch correctly when an associated file is dragged to the app's icon or to the app's document area (when it is open and active). This is a clue that DDE is working properly.
I have attempted to trap the error using a try/catch macro in InitInstance() and InitApplication() but to no avail. I don't think this error is being created from my application, but perhaps from Windows XP and/or Windows 2000, as the error occurs on both OS's.
Well, that's all I have for now. Thanks for your continued support.

Is your app really located at <path>\<filename>? You can experience this behavior if you're incorrectly registering the application path. I've occasionally found this problem in my development environment, since the application working directory is just one level up the Debug or Release subdirectory.

Joaquín,
I understand your point, however the <path>\<filename> I wrote of is the path and filename of the associated file. This path and filename given in the error is actually the correct path and filename of the associated file I double-click. Think of this problem as double-clicking on a '.xls' file in order to launch excel with the '.xls' file loaded in the document area. Strange behavior from Windows, but not without explanation I'm sure.
Thank you,

Umm... maybe the following will help you find the problem: Open the registry with regedit and look for HKEY_CLASSES_ROOT\.xxx (where xxx is the extension associated to your app). The value for this key should be something like "XXX.Document", look for this and open the subkey shell/open/command: is what you see correct, or can you spot something ugly which might be explaining the problem? HTH.
