I've inherited an old vc++ 6 project, and loaded it into 2005.
Cleaning up the project, I tried removing a file called resource.hm, which contained the following line:
<br />
#define HIDC_TEST_LIST 0x80d43575 // IDD_TEST_DIALOG [Neutral]<br />
The IDD_TEST_DIALOG dialog does not exist in the project, nor are any of the resources defined as Neutral.
I also removed the following lines from the .rc file:
<br />
#define APSTUDIO_HIDDEN_SYMBOLS<br />
#include "resource.hm"<br />
#undef APSTUDIO_HIDDEN_SYMBOLS<br />
When I build, the lines are auto-generated in the resource script, and an empty resource.hm is created, causing a compile error.
From MSDN:
Your project's resource.hm file will only be created by the development environment when one or more dialog boxes have controls and when those controls have HelpID properties set to True in the Properties Window.
I scanned the .rc script for any references of HIDC_TEST_LIST, and none were found. I scanned for other HelpIDs, nothing. How in the heck do I get rid of this thing?

Delete and re-create the resource file, at least thats how I get it to work when loading problematic files into VC6.

Well I was able to recreate your problem. Then I was able to fix it too.
One or more of the controls in the dialog could be having help ids. Set this property(Help ID) to false. Each control in a dialog has got this property. Once you set this to false the lines that you mentioned
Jack Squirrel wrote: // Generated Help ID header file
#define APSTUDIO_HIDDEN_SYMBOLS
#include "resource.hm"
#undef APSTUDIO_HIDDEN_SYMBOLS
will not be regenerated. This should fix the errors that come up.
Help ids are located in resource.hm. Once you delete the above statement you are bound to get errors because the file is no more included and the symbols are undefined.

Yep. I searched for HID* in the .rc file and didn't find anything. I thought it might be corrupted, since if a control was set to true, it's label should be appearing in the .hm file. I then went through each dialog (100+) in the resource editor, selecting all controls and ensuring the HelpID was false. One of the dialogs had it set to true for all controls, but all of the controls were unlabelled. (set to their ID numbers)
I created a new project, set the HelpID flag to true, and changed the ID to a number. (1001) Sure enough it failed to compile.
I tried changing the ID to TEST, and it wrote the help ID in the .hm as HTEST. I guess the HelpID writer doesn't like IDs starting with numbers - H1001 should be a valid label for a #define.

Hi ,
This is my first posting over here. Hope to have great answers here. 
I have a (Dialogbox with a button) which I open from the Menu which is
vertical shaped and docked at the left side.
I click this button on the dialogbox and AfxMessagebox is flashed which
is at the center of the dialogbox . In that way its flashing at the
left side. I call a App's DisplayMessage function in order to show this
messagebox. I though if I display this dialog from App , it may come at
the center but that is not the case.
I want this AfxMessageBox to be flashed at the center of the frame.
I read few postings here. I used following code using SetWindowsHookEx.
Sombody before said to subclass the window of AfxMessageBox in the hook
procedure . I am not sure how to do it and after that how to reposition
the window at the center of the main framme/App. So I straightaway used
SetWindowPos but not working satisfactorily.
HHOOK hookSave;
LRESULT CALLBACK hookFunc(int nCode, WPARAM wParam, LPARAM lParam)
{
if ( HCBT_CREATEWND == nCode )
{
#define pcs (((LPCBT_CREATEWND) lParam)->lpcs)
HWND hwndSave = 0;
if( WC_DIALOG == pcs->lpszClass )
{
hwndSave = (HWND) wParam;
}
if ( hwndSave )
{
// subclass_dialog_any_which_way_you_want(hwndSave);
SetWindowPos(hwndSave,HWND_TOP, 10,50,500,300,SWP_SHOWWINDOW);
//MoveWindow(hwndSave,100,500,500,300,false);
//theApp.m_pMainWnd->SubclassWindow(hwndSave);
}
#undef pcs
}
return CallNextHookEx(hookSave, nCode, wParam, lParam);
}
void CLeeApp::DisplayMessage()
{
hookSave = SetWindowsHookEx(WH_CBT, hookFunc, NULL,
::GetCurrentThreadId());
AfxMessageBox("Just for check");
UnhookWindowsHookEx(hookSave);
}
I guess this related to making AfxMessageBox as a SubClassWindow to
MainFrame which should be subclassed in the hook function (Which I dont
know how to do in the hookfunction, means hot to get the main frame
handle) and then how to get the windproc of mainframe for afxmessagebox
and then hot to get all these things to work for Afxmessagebox to
center the mainframe
Could someone help me with some guiding code postings.
It will help me a lot.
Thank you,
Lee

Instead of using AfxMessageBox(), use the CWnd::MessageBox() method on the window you want the message box to be centred in, ie. If you want the message box centred on your main frame, call AfxGetMainWnd()->MessageBox(...).

Thanks RYan ,
It helped
Just for learning purpose.
How to achieve it with AfxMessageBox using SetWindowsHookEx
and hook procedure?
How to subclass AfxMessageBox window to main window in the hook procedure and then how to to resize it. (please refer my code).
Thanks,
lee

I wouldn't ever do it that way, so I don't know how you'd do it.

Message boxes are automatically sized? Why do you need a different size?

In the name of code reuse, does anyone have pointers to articles that give examples of how to automate another app?
Scenario: I'm writing an app that helps me do part of my job much faster. However, I must still manually copy and paste data from an existing .NET app into mine.
Therefore, I'm looking for code examples of how to programmatically control the other app the way I would do so manually.
Ex:
1) F4, enter data, press enter
2) Copy from fields
3) etc.
Most of this I can guess, FindWindow (to locate app's main window), figure out how to send keystrokes, GetWindowText on specific windows, etc. I'm just hoping someone's already done something I can use real quick instead of blowing a few hours stumbling through it.

Thanks Nibu. That gets me the SendKeys bit, but the hardest part is getting the data from other app. Generally, that's not too difficult with a standard Windows app. However, it's a .NET app so I'm not sure how to programmatically find the specific windows I need. Looking at Spy++, I can see several issues: 1) they all have the same class name, 2) what I would normally see as a listbox evidently is something else and so on.
Therefore, what I'm looking for is an example of a C++ program driving a .NET application and basically screen scraping from the .NET apps windows.

With a .NET Framework-based application, the window messages and classes intercepted by Spy++ don't correspond to anything useful. You want to see managed events and property values. See here for more.

Yep. I remembered this article last night. It's not 100% what I wanted in that it doesn't show how to find a particular window or what I'm capable of searching for, but it's definitely a start.
Thanks David.

Can anyone tell me what are the diiferences between Visual C++ and Managed Extensions for Visual C++, in terms of code, not architecture? I'm relatively new to VC++.
|
|
|
|

Are you looking for MC++ or CLI?
MC++ is the original Managed Extensions syntax for writing .NET code with C++
C++/CLI is the new syntax introduced with Visual C++ 2005

I want to write a program to capture the displaying content on entire screen, whatever it's displayed by OpenGL, DirectX, or Window GDI. I wonder it might be a hard-to-slove issue, maybe need to write a Display-Card drive, anyway, i have no idea. Please help.
|
|
|
|

no its possible and easy to do. check this[^] article for how to do it. Dont get confused with section about directx, using GDI will be sufficient directx is just another way to do it.

Thank you for your replying. Yeah, before i post i've been already read this article. Actually, it's a bit out of my question, that's it's just for capturing screen contents that diaplyed by DirectX or Windows GDI, but doesn't work if displayed by OpenGL as i think and many friends suggested so. Is there any only one way to capture the screen's content whatever where they're come from? Thanks a lot!

|

|

So sorry that i just realized the article you suggested can solve my question for both DirectX drawing or OpenGL drawing, i guess maybe the DirectX Way of captuing captures the content directly from Displaying-Card, so great! Thank you!

I have a set of custom controls (for pushbutton, checkbox and radiobutton) originally written in C++ and using standard GDI. Last year I added support for UxTheme API, and everything seems to work okay.
Right now, I'm adding GDI+ support, and most things seem to work fine. The only problem is that I can't get UxTheme API and GDI+ to work together perfectly. It's *almost* right, but not quite.
The code for this looks roughly like:
hdcScrn = BeginPaint( hwnd, &ps );<br />
hdcOffscreen = CreateCompatibleDC( hdcScrn );<br />
hbmpBuffer = CreateCompatibleBitmap( hdcScrn, nWidth, nHeight );<br />
SelectObject( hdcOffscreen, hbmpBuffer );<br />
<br />
<br />
DrawThemeBackground( hTheme, hdcOffscreen, BP_PUSHBUTTON, nState, lprcClient, NULL );<br />
<br />
BitBlt( hdcScrn, 0, 0, nWidth, nHeight, hdcOffscreen, 0, 0, SRCCOPY );<br />
The new GDI+ version is pretty similar, except that I'm using Graphics* and Bitmap* objects. When I get to the part for DrawThemeBackground, I'm doing this:
hdcReal = hGrfx->GetHDC();<br />
DrawThemeBackground( hTheme, hdcReal, BP_PUSHBUTTON, nState, lprcClient, NULL );<br />
hGrfx->ReleaseHDC( hdcReal );<br />
The problem is, when I draw the offscreen buffer back to the screen, the edges of the pushbutton are too dark. It looks almost as if UxTheme call is not using alpha correctly, so the outer edges are too dark.
I'm not sure if there's a good way to post screenshots on the site, so I've posted them on my own site.
std GDI version
GDI+ version
As you can see, the dialog background is a custom texture, so I don't think I can call DrawThemeParentBackground.
Anyone hints or help on this would be greatly appreciated.

I am about to switch to using VC++ 2005 Standard as my main development platform, and after reading a previous blog on the new Visual Studio 2005 I know I need to...
1) Patch the STL header directly by doing the following to fix the major STL stream leak bug. This saves having to rebuild the CRT library and then shipping this with your app  :
1) Open up istream in \Program Files\Microsoft Visual Studio 8\VC\Include<br />
2) Before line 29, insert the following code<br />
<br />
explicit __CLR_OR_THIS_CALL basic_istream(_Mysb *_Strbuf, bool _Isstd, bool _Noinit)<br />
: _Chcount(0)<br />
{
if (!_Noinit)<br />
_Myios::init(_Strbuf, _Isstd);<br />
}<br />
<br />
3) In the same file (istream), look for the following line:<br />
<br />
: basic_istream<_Elem, _Traits>(_Strbuf, false),<br />
<br />
and change it to:<br />
<br />
: basic_istream<_Elem, _Traits>(_Strbuf, false, true),<br />
2) Due to built-in search being slow, use a macro so searches can be performed using Google or MSDN2 from within the IDE

Is there anything else (tips, problems) that's worth knowing ?

I have a WindowsXP memory question. I have a program with one thread and a windows messageloop that runs in mainprocessthread. I create two windows. The memory usage is about 1mb, I minimize one window, and the same memory usage. But when I minimize the second widow so all windows are minimized the memory usage goes down to 200k. I have tried to simulate this programmaticaly (minimize all windows) but I have only managed to get WindowsXP to cache away the memory when I minimize the windows manually... anyone got any info on this?
