Yeah...

This can happen if the message loop for the program is defective or the quit message isn't being posted. The window closes, but the application still sits around running.

I'm going to patent thought. I have yet to see any prior art.

First of all why do u need to distribute MFC42.DLL?? ur not supposed to do that....
Just build ur application with Option MFC Statically Linked instead of Shared Dll.... ok?? then u need not bother abt whether the target does contain which DLL...

hope this works for u....
gud luck

Actually, you can. You may not distribute MFC42D.DLL, but that's a whole other issue.

What I would do is to get hold of VCREDIST.EXE from microsoft.com, and install that on the client machine instead.

Succession of modal dialog boxes

BadJerry12-Dec-03 2:03

12-Dec-03 2:03

I need to show a succession of full screen modal dialog boxes. And I would like to avoid the flickering between them...

My code looks somehow like this (in its very simplified version)

<br />
while ( isContinue )<br />
{<br />
   CMyDialog dlgDialog;<br />
   if ( dlgDialog.DoModal() ==IDCANCEL)<br />
      isContinue = false;<br />
}<br />

Any ideas? Thanks!

In this scenario, there is no way to avoid the flickering because the dialog boxes are being created and destroyed each iteration of the loop. Explain a bit further what you are after and we might can come up with a better design.

I understand that the dialog gets destroyed and that triggers the flickering.
But I have tried something like this

<br />
CMyDialog * pdlgOld = NULL;<br />
while ( isContinue )<br />
{<br />
   CMyDialog * pdlgDialog=new CMyDialog;<br />
   if ( pdlgDialog->DoModal() ==IDCANCEL)<br />
      isContinue = false;<br />
   if ( pdlgOld != NULL )<br />
      pdlgOld->DestroyWindow();<br />
   pdlgOld = pdlgDialog;<br />
}<br />
if ( pdlgOld != NULL )<br />
   pdlgOld->DestroyWindow();<br />

and overriden CMyDialog::EndDialog so it would return the value (by calling EndModalLoop) but not actually call ::EndDialog

But that does not seem to work!

Modal dialogs are not designed to be operated in such a fashion. What is the net result you are after?

Then use a CPropertySheet object in wizard mode.

This would be indeed the orthodox way, but the interface is a bit more complicated... I also need other buttons and the user can define where they will appear and how... that's why I need the dialog boxes!

Sorry to waste your time with my weird interface needs!

Since each page on a propertysheet is derived from CDialog, you can design them as necessary, both at design time and at runtime.

It all depends on the apartment model you're using. Take a look at this: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dncomg/html/comthreading.asp[^]

Cross-thread COM invocations may be.. uhm.. hard to grasp at first. Just give it some time. Smile | :)

Smile | :)

Here's a CP article that touches the subject if you need a reference: http://www.codeproject.com/com/jbcommailslot.asp[^]. Eventhough it talks about COM events having to be marshalled across thread boundaries, the same principles applies in your case as well (COM events / connection points are nothing but fancy standard COM callback interfaces).

Hiya,

I'm trying to find a DirectShow H263 encoder/decoder pair that works with frame sizes other than 176x 144, especialy as the camera I'm using doesn't output in this size (a slight issue Cry | :((

Cry | :((

).
If anyone knows of one, I'd be grateful to know of it!! (Especiall 640 x 480)

Many Thanks

Hi Marty,

glad to see you again.
You can prorammatically switch on Autocheck property, and also easily decrease its interval to e.g. 0.1s (after first retreaval you can switch it off)

1.Get the GUID value of HKCU\Identities\Default User ID
2.Set HKEY_CURRENT_USER\Identities\{GUID}\Software\Microsoft\Outlook Express\{...version...}\Poll For Mail to desired intervall in millisec
3.Set HKEY_CURRENT_USER\Identities\{GUID}\Software\Microsoft\Outlook Express\{...version...}\Dial during Poll to

2 for switching off
1 for connecting when offline
0 for connecting when online

EXE Doubles in Size with every Resorce Compile

Lucky the code machine12-Dec-03 0:47

Please Help me!

Every time the Resource is re-compiled (ie i move a button) the resource file will grow & cause the EXE file to double in size. A work mate has had the same problem in the past. The problem is with the MS FLEX GRID control causing the Resource (rc) file to grow. My work mate was able to fix this problem by formating his HDD & re-installing everything then using an old rc file that he then had to update. His code has been happy ever after but what is to say it wont happen again. This is an option for me but we need to understand the problem to stop it happening again.

If I look at my rc file other controls are fine: (example)

IDC_AttenOffset, 0x403, 7, 0
0x2e35, 0x2035, 0x4264, "\000"

But If you look at any of my 3 MS FLEX GRID controls:

IDC_GRID, 0x37a, 302, 64
0x0024, 0x0000, 0x0037, 0x0032, 0x0045, 0x0036, 0x0037, 0x0031, 0x0032,
0x0030, 0x002d, 0x0035, 0x0039, 0x0035, 0x0039, 0x002d, 0x0031, 0x0031,
0x0063, 0x0066, 0x002d, 0x0039, 0x0031, 0x0046, 0x0036, 0x002d, 0x0043,
0x0032, 0x0038, 0x0036, 0x0033, 0x0043, 0x0033, 0x0038, 0x0035, 0x0045,
.............. This goes on & on for 40MB!! WTF | :WTF:

WTF | :WTF:

Someone else must have had thid problem. Please help me!

I had this before and I ended up manually erasing the extra stuff that was full of 0x00 and then it never came back.

The flex grid is for free but it sucks sometimes....I know

Thanks to both of you. I had tryed that before with no luck as I think my 40MB Resource file was too far shot.

I did solve the problem tho by creating a new dialog on another PC & adding a fresh MS Flex Grid. I then Copyed this section from the Resource file & Pasted it into my Project Resource file in place of the currup ones. Then After re-loading into C++ I re-applyed my previous Grid Settings & Re-compiled.

The EXE & RC have stopped doubleing & My EXE went from 20MB back to 700K!! Cool | :cool:

Cool | :cool:

so how would i run this file from my c++ program, and how'd i load the results back into a char buffer or something
