You cannot use CFileDialog to save the File, you have to implement you logic for that.. But you can open it in Save As mode by specifying FALSE in construtor while creating CFileDialog object..

like this

CFileDialog dlg(FALSE);

HI!!!
I am working on an MFC Application. When I view the class wizard an error occurs which is:

Parsing Error: Expected ";"
Input Line: "void Convert(CString str1,CString str2);"

I had checked the application. But, I didn`t understand the cause for this type of error. Wat may be the problem? Wat should I do?

Thanx a lot

MSXML6.lib error on Debug build

Hi,

compiler: VC++ 6.0

problem:

When a Release Build is done, it works fine..

We are using MSXML 6.0 in our code.

But during Debug Build of a win32 module, it gives the following error.

msxml6.lib(msxml6_i.obj) : fatal error LNK1103: debugging information corrupt; recompile module
Error executing link.exe.

One possible reason we could think of is the msxml6.lib is of release build. so it builds on release mode and gives the error on debug build

We need a Debug build since we need to debug the code, can anybody suggest any work around in the compiler setting..

I tried out the following
try out the following, but no use:

Turn off optimization with the /Od (Disable) option.
Disable minimal rebuild with the /Gm– (Enable Minimal Rebuild) option.
Compile with the /Gy (Enable Function-Level Linking) option to package functions.
Use a different code generation option. See the /G (Optimize for Processor) options.
Change the order of functions and global variables.

I get the same error when I enable the Debug option of compiler in Release Mode.

Any suggestion or workaround is highly appreciated.

Thanks,

Shiva

GDI+ Bitmap/Graphics::DrawImage(..) Question..

fetox29-Nov-05 0:54

hi,

i'm using GDI+ in a MFC based App under Visual Studio .NET and have a problem with the Bitmap class.. if i use the following code in some drawing function, it work's perfectly well (although slow, cause of the steady reloading of the image, which is crap..)

void DrawSomething(Graphics *g) {
Bitmap myBitmap(L"somepicture.png", false);
g->DrawImage(&myBitmap, RectF(somecoordinates));
}

now i'd like to keep the Bitmap object resident, by adding static in fron of the Bitmap declaration, or some new/delete construct in the embedding class, but in every case my Bitmap(-Object?) seems to be lost.. no error, no display of the image!? even Bitmap::GetHeight() returns 0 in that case, without crashing.. .NET framework issue? but it's unmanaged code, so garbage collection should not happen..

any ideas??
regards
olli

I am not sure how well this could perform, but this will work. You may read the information pixel by pixel and store it into a file. Say, XY(31,45)=RGB(132,53,90); and while opening a file, you could read this file and paint accordigly. I know this is a very crazy way of doing it, D'Oh! | :doh:

but may be a temporary solution for you.:->

Worker Thread related problem?

dp_7628-Nov-05 23:20

dp_76

28-Nov-05 23:20

The Worker Thread in my MFC SDI Application does some heavy job.
The user can stop in between by pressing the <stop> toolbar button or Tools menu -> Stop.

To enable the Stop toolbar button before the control enters the worker thread, i have used the following line of code:

pApp->bDiskReadProcessStarted = TRUE;
pframe->pToolBar->SendMessage(TB_ENABLEBUTTON,ID_TOOLS_STOPCURRENTPROCESS,(LPARAM)MAKELONG(TRUE,0));

& then is the code for the creation of the Worker Thread:

pApp->pWorkerThread = AfxBeginThread(MaskingFiles_WorkerThread, (void*)pApp->MFC_Obj);

BUT as a result of the above code the Stop button is enabled only after the worker thread has completed. where as i wanted it to be enables before the start of worker thread.

code in the OnUpdateUI for Stop button:

void CMainFrame::OnUpdateToolsStopcurrentprocess(CCmdUI* pCmdUI)
{
CStellarPhoenixApp *pApp = (CStellarPhoenixApp*)AfxGetApp();

if(pApp->bDiskReadProcessStarted)
{
pCmdUI->Enable(TRUE);
}
else
pCmdUI->Enable(FALSE);
}

I donot understand y this is happening.

Waiting for suggestions

OpenGL and very big images

Hi all,
I'm finish to write a software to visualize very big files showing thats as an image that could be bigger than 1000x1000000 pxl (so very very long images).
I choosed to don't load the all the file into RAM (required from 100MB to more than 1GB), but load only some rows and colums building a sort of undersampled image: in this way I need only 2/5MB of RAM memory. And at the moment the visualizator is very fast.
Now I'm thinking that a future version of that software could show (in 3D) with OpenGL more files showing thats one on the other, like some sheets of paper that surely you have behind your eyes on your desk.
I'm a beginner in OpenGL so I'm asking myself if, with this big files, it is possible or not to do that in an efficient way without lose a lot of CPU-speed!
Can you tell me some good tips/news? Some good articles?
Thanks in advantage, Matteo.

SetUnhandledExceptionFilter() difference Windows 2K and XP

StHubi28-Nov-05 21:11

28-Nov-05 21:11

Hallo,
I have been working for a long time with Windows 2000 with SP4 as my operating system. Now I have moved to Windows XP with SP2. Unfortunately that had a nasty side effect I cannot yet understand:

When I do run a debug version of my application outside the debugger and an exception occurs, Windows 2000 notifed me about it and I could choose "Retry" to debug the application. The IDE came up and I got every information about the stack and its variables.

Under Windows XP the "Retry" button was replaced by "Debug", but when I use it the IDE comes up and I do not get any useful stack information, just Assembler code that is not very useful for me.

Finally I found out that this behaviour is connected to the SetUnhandledExceptionFilter() function. Without it even Windows XP will show me the stack information. But I really need my custom exception filter, so I cannot leave the application without it forever. Does anyone know how to get the full stack information under Windows XP?

Thanks,
StHubi

The list control is probobly storing the column width as an int, 32767 being the maximum value for an int theres going to be no easy way around it. Might seem like a stupid question but why the hell whould you want a column that big for anyways...? Confused | :confused:
