CFileDialog restriction

Hi
I want to make sure the user can only browse and only click a file named 'myprogram.exe' in the CFile Dialog (open)

Didn't find any flags restricting this.

Any ideas?

Best regards
Jens

This severly defeats the purpose of using CFileDialog, does it not? If you're only allowing the selection of one file, why bother asking for it? Have you considered using SHBrowseForFolder() instead? With whatever folder is selected, tack 'myprogram.exe' on to the end.

Preserve an MDI child frame's size

In an MDI application when more than one MDI child frames
are open and one of these child frames is maximized when
we toggle to other frames, they are maximized too
regardless of their previous size.
I checked the UINT nType passed to OnSize message handler
in MDI's view class but its value is always 0
(SIZE_RESTORED).
How can I preserve an MDI frame's previous size including
maximize, minimize or restore status after toggling to
this frame from another maximized MDI frame?

Thanks in advance

dumpbin /export your.dll

bitmap or icon ??

hi,

i have a dialog app. when i hit the start button i want to perform some steps and indicate each step with a little picture (one for failed, one for pass).

what should i use for this?

icons are always drawn big. i only need them to be 8x8. but if i use bitmap the background is not transparent.

how do i get what i want? or should i use something totally different?

code examples would be cool.

greets.

You can use a 16x16 Icon, draw your 'indicators' in the middle and leave a 4 pixel transparent border on each side.
For this you simply darw your icons, load them and draw.
If you get a stretched version of your icon (I aksed this question yestarday Smile | :)

Use LoadImage to indicate the desired size for your icon.

You can also use a bitmap with a mask-bitmap to mask out the transparent color, but I think Icons would be the easiest way for you.

I want to create a new document/view making its frame hidden till some lengthy operation is done and then show its frame, so I passed a FALSE value to CDocTemplate::OpenDocumentFile ‘s second parameter BOOL bMakeVisible in void CMainFrame::OnFileNew() message handler:

CMyDoc* pDoc = (CMyDoc*)theApp.m_pCPDocTemplate->OpenDocumentFile(NULL, FALSE);

How do I have to make this document’s frame and view visible again?

I believe Nero has a pretty good API that you can use. Check out this forum for more information:

Hi!
The Nero api is pretty good but I recommand using something more general... Nero SDK only works if there is a nero burning program installed on a computer and everyone doesnt use nero...(but it is easier to use)
You can use the imapi.h header file which you can get by downloading the latest Platform SDK ( it includes cd-writing ) ... ( your program will work on computers with windows XP or with some other windows edition with a service pack )

Well... I am a beginner ...

Hi All,

We need to debug DB2-C Stored procedures sitting on Z/Os
(IBM). Those are embedded SQL C programs. We are using
Db2 Connect 7.2 to connect to the database. Now I want to
debug those C programs in VC++ editor.

If somebody has solution pl write to me.

You'll probably need to set up remote debugging[^] with Visual C++ on the server.

You'll need to attach the debugger to the process that will run the C code - this is probably the DB2 executable, although I don't know which one this is - I'm not familiar with DB2.

You are running a loop from 0 to 32. Thats 33 times, but you only alocated space for 32 chars.
You need to alocate enough space (and dont forget the trailing zero for a string!).

Hope this helps

Who is 'General Failure'? And why is he reading my harddisk?!?

You missed the <= 32 so it stops at 31, although it would be better writte as < 32

Get into the habit of using sizeof() eg.

<br />
CString vChr;<br />
TCHAR pbuff[32];<br />
CString Out;<br />
<br />
int num=0;<br />
int nOffset=0;<br />
int nRead;<br />
<br />
//read in the 1st 32 bytes<br />
do<br />
{<br />
  for (int f=0; f<sizeof(pbuff); f++)<br />
    pbuff[f]=NULL;<br />
<br />
  sName="";<br />
  nOffset+=sizeof(pbuff); <br />
  nRead = SimMem.Read(pbuff,sizeof(pbuff));<br />
<br />
  int nLen=0;<br />
<br />
<br />
  int a = (int)pbuff[11]+128;<br />
  TCHAR ch = (char)a;<br />
<br />
  for (f=0; f<10; f++){<br />
    sName += pbuff[f];<br />
}<br />

It will stop you hitting annoying bugs like this...

hi,
i am facing strange problem with IDM_PRINT.
i am using the brochure machine sample of microsoft and my own custom print template.it is working fine with the IDM_PRINTPREVIEW and i am able to see the desired result.when i try to use IDM_PRINT to print it directly,it justs does nothing.neither it invokes the print dialog nor prints .if i pass the printtemplate path as null the print dilaog comes up and prints.this seems to be very strange .would you please suggest me how you dealt with this problem.
thanks a lot

Memory Management

8-Sep-03 22:18

Hi All, I'm using malloc, realloc and free to maintain variable length memory blocks, which I intend to use for a container template class. What I would like to know is how to initialise parts of the block by calling the constructor of my object of type T? I use malloc if the block is null and realloc if it isn't so initialisation is quite important (otherwise realloc will get called on a duff address == crash Smile | :)

). Trouble is I can't use calloc to initialise the block bytes to 0 cos it'll only initialise the container the first time round (realloc is used thereafter), and secondly I have objects of x bytes that have _vfptr's which should not be NULL. So is there anyway I can initialise a new object when I allocate enough space for it? I can't use placement new because I need the allocation to grow or shrink. Aside from creating an object on the stack and memcpying it, I was hoping to be able to allocate the space and then call the objects constructor using that allocated space for its containment, anybody got any ideas? Thanks all for reading this far.

Alan.

AFAIK malloc is a 'C' function.

The operator new in C++ also calls that constructor. If you go with the C++ way of doing things - if you're using templates you have to be using C++, you can allocate a contiguous block of memory, then use placement new to construct the objects. Thats how the STL allocators work.

Don't forget mixing new and malloc is just asking for trouble...
