Thanks for the long answer. I have the sneaking suspicion you've used this code already?
As I said to Michael, its kind of nice not having a one line solution. That would be
a touch embarassing. I usually *answer* (some of) the questions here after all!
Iain.

I've been running into a weird problem. I have a header file that has the following in it:
#ifdef _DEBUG
#pragma comment(lib, "SomeLib_Debug.lib")
#else
#pragma message("Argh")
#pragma comment(lib, "SomeLib.lib")
#endif
This header file is included in a static library, we'll call it "A.lib".
I have a program, "B", that includes "A.lib". A and B have Debug, Release, Unicode Debug, and Unicode Release builds. SomeLib just has a Debug and Release build.
B uses A.lib, but does NOT include the header shown above. In other words, it should not need "SomeLib.lib".
When I compile it in Debug or Release, it compiles fine. If I compile it in Unicode Debug or Unicode Release, it seems to require SomeLib.lib, and the link fails.
Any idea as to why this might happen? I've scoured through the project settings and can't find any differences that would explain this.

When A.lib compiles this file, it will place the requirement for SomeLib.lib (or SomeLib_Debug.lib) into the associated obj file, which is then included inside A.lib. That means that when the linker is used to link A.lib into an executable, it will find the comment, and so try and link with SomeLib.lib as well. You can turn this behaviour off by checking the "Ignore all default libraries" option on the Project->Link settings, but this will mean you will have to manually link with all the standard libraries (MFC links with about 8 libraries using this method).

That makes sense, and that's kindo f what I was afraid of, but it doesn't make sense that it would fail to link only for some configurations (namely, the Unicode ones only.) I guess I was wondering why some configurations would behave differently from others, even though their settings regarding libraries seem the same?

How do i open an Dialog BOx from the SDI Main Frame Menu. I tried to use Do.Modal()with the Dialog class object , but it caused an assetion. If i ignore the assertion, it runs perfectly fine. I want to get rid of that assertion.
|
|
|
|
|
What causes the assertion? SDI menu has nothing to do with a dialog box. I suspect that the dialog box is not initialized correctly.

I created an object of my Dialog class called Window.In order to open the dialog class i did Window.DoModal();
That is when assertion came up.
|
|
|
|
|
|
assertion says
Debug Assertion failed.
File:afxwin2.inl
Line 162.
i think it is due to some inappropraite use of function DoModal().

Can you post the code that you are using to create the dialog box as well please... it might make it a bit easier to see what is going on.

It could be that your dialog contains a CWnd derived member that's not linked to a control. But it's impossible to say for sure unless you post some code.

here is the Function that is used to create the dialog box when a SDI menu item is clicked.That menu item is called Jaguar.
Jagwindow is my object for class CJaguarDlg.
Hope this clarifies things.
void CVR_ToolView::OnJaguar()
{
CJaguarDlg JagWindow;
int nRet=JagWindow.DoModal();
}
|

Sadly, that's of no help. How about posting the OnInitDialog() of CJaguarDlg. Also post its .h file.

No. Somewhere in your dialog or in one of the embedded controls, a RedrawWindow() is being called before the dialog is created properly, possibly in OnSize() or something like that. If you've put this in, then do this:
if(::IsWindow(m_hWnd))
RedrawWindow(); Hope this helps,

I am working on a text editor (uses richedit, MFC, SDI) that on right mouse click, in certain situations, will spawn a control for a value to be input. An edit box, or list control, for example. I was developing the software on Windows 98 (bah), and it was working fine, but when I tested on XP, I hit a wall.
The thing is, the controls are supposed to dissapear once they lose focus (setting a value). Initially, the controls were losing focus instantly after creation, which was driving me insane - I dont know the cause still. So I rewrote the code to act not when focus is lost, but when the user clicks on the rich edit view (out of the control). It fixed the instant close problem, but I have found now that the controls seem to act as if they are not there. The cursor does not change when it goes over the control, and clicking on the control is as if clicking on the view outside of the control.
I assume XP has a different way of handling the rich edit system or something like that. Should I just recompile on XP, or what?
Here is my control creation process:
1) Create an instance
2) Call create (WS_CHILD | WS_TABSTOP | WS_BORDER are my common styles)
3) Set the data (list selections, edit box initial text, etc)
4) Set the font
5) Reposition with SetWindowPos, setting the control topmost in Z order, showing the control, and moving+sizing the control
6) Set focus on the control
It is a bit dragged out like that because the manor in which it is handled (3 different control types are handled by the same creation routines).
Any ideas? Thanks.

I'm currently using controlbars (stingray studio SECControlbars which are derived from CControlbar) and I'm trying to limit the size that you can reduce them to. Currently, i'm able to catch the WM_SIZE message in my SECControlbar derived class, but im not entirely able to control the actual sizing. What happens is i catch the size message and im able to see what size is requested, but when i attempt to change the size and pass to the base class, the results are incorrect.
In my specific case, im trying to limit the width of a vertical controlbar to 132 or more pixels. What happens with my code is the first sizing that goes below the 132 barrier actually happens despite my efforts to stop it. When i size again (also attempting below 132) the size is adjusted towards my 132 barrier but not exactly right and depending on how small i actually tried to make it. These two results happen one after the other, so every other size appears to try and size correctly. I think im setting my size after the actual controlbar size is interpretted but i can't seem to find the message i should capture and override to prevent this. I've tried using spy++ on the window but i can't seem to find any other messages that could be responsible. I also think I could be misusing the CalcDynamicLayout() function, but i've tried most all of the options and it doesnt seem to matter all that much. Any solution for a CControlbar should work in this situation, but i haven't seen one in any examples.
Here's part of my OnSize handler:
void VHelpDlg::OnSize(UINT nType, int cx, int cy) <br />
{<br />
<br />
VMainFrame *pMainFrame = static_cast<VMainFrame*>(AfxGetMainWnd());<br />
if(pMainFrame)<br />
VGENyDoc* pDoc = pMainFrame->GetDocument();<br />
else<br />
return;<br />
<br />
CSize szCtrlBar;<br />
<br />
if(this->m_szDockVert.cx<132)<br />
{<br />
this->m_szDockVert.cx=132;<br />
cx=132;<br />
szCtrlBar=CalcDynamicLayout(132,LM_COMMIT|LM_VERTDOCK|LM_STRETCH); <br />
}<br />
SECControlBar::OnSize(nType,cx,cy); <br />
Invalidate();<br />
}<br />

Straight from the documentation:
The framework calls this member function after the window’s size has changed. The parameters passed to your function reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this function, that implementation will use the parameters originally passed with the message and not the parameters you supply to the function.
You need to look at CWnd::OnGetMinMaxInfo().
|
|
|
|

I put a handler for WM_GETMINMAXINFO in as OnGetMinMaxInfo() but sizing the control bar never results in the program entering this code. I'm not sure if this control bar acts like a standard CWnd, the WM_SIZING message never gets called either. Perhaps this message is being handled for me at a lower level class?

Hi Everybody,
I've spend some time trying to attach a dialog to winamp 2.xx(like the Plugins for winamp). It's not a Plugindll, but an indipendent exefile. I've tried to do it with;
HWND m_hWinamp = FindWindow("Winamp v1.x",NULL); //Find Winamp
CWnd pWin;pWin.m_hWnd = m_hWinamp; //(Is this possible?) I've tried to generate a CWnd for the Createfunction
//this code is for making the modeless Dialog
CTestDlg *dlg = new CTestDlg;
dlg->Create(IDD_TEST_DIALOG, &pWin);
dlg->ShowWindow(SW_SHOWNORMAL);
But i get an abnormal program termination in the dlg->Create(IDD_xyz, &pWin) line as i run the program. Is it after all possible to attach my own window to an other program, or is there another, better way to something like that?
Thanks for your help! I hope i've explained it clearly
