Hello.
1. How to change in CSplitterWnd actual splitter thickness?
2. Can I put control on the splitter strip (like button or ...)?
Thanks.

Read through winsplit.cpp (MFC source). You're gonna derive a class from CSplitterWnd, and adjust the width (and handling of mouse clicks or whatever) that way.

Hello guys ,
I am working on a project where I need to implement 'exact' timers , after asking some questions on CP forums and some searching I decided to use multimedia timers.
We know that the main minus of Multimedia timers is that they depend on the 'resolution' of the timer and this 'resolution' is system dependant , so here comes my question : Have you experienced any problems using these timers ? Like there were cases when 'resolution' was too big and the accuracy of the timer was very bad ?.
thanks in advance

Which will not be possible unless you are working with a RTOS. You can, however, use the multimedia timers to realize a few ms resolution that is simulated.

I know that David that is why I had put word exact in '' symbols.

I know that but I can not for example implement a timer with resolution of
1 Millisecond , because the minimum value of resolution is system dependant.

I don't know what are you developing/how, but if you in the sepparate !worker thread! you can consider Sleep. Or combiantion Sleep/while/GetCurrentTick

Hello
I seriously need help on this. Please take time listen to my problem.
We have a SQL 2000 database running for a year. the main table called 'datatable' has grown to 1.8GB. Now we want to change the old database name to a different name without losing all the data in it. We made full backup of the old database and create a new empty database and restore the old database to it.
After I done that the program that populates the "datatable" in the newly restored database always give me error (IDispatch error #3121: [Microsoft][ODBC SQL Server Driver]Timeout expired :Microsoft OLE DB Provider for ODBC Drivers)
when rs->Open("DataTable", _variant_t((IDispatch *)conn,true), adOpenKeyset, adLockOptimistic,adCmdTable); excuted.
I have tried to recreate table index. It still doesn't work.
The datatable has first column "ID" as integer AutoNumber.
If I truncate the table, the program works fine. If I delete most of the data
for example only keep last a few hundred rows, the program also works.
If I don't use rs->open and rs->addNew() method to insert data, instead of using a simple insert SQL query, it works fine.
I believe the problem is that when we do restore something got messed up, but
how? If the datatable is too big and need more time to process when we call rs->open, but why the old database doesn't have this problem. The same program are running on those two databases. Any ideas?
Please help me out.

Hi,
I would like to ask if someone can help me to resolve the following problem I am experiencing while writing graphical images from an AutoCAD drawing into device context (metafile in a vector format (EMF) ). My C++ code, running on Win32 platforms, is using GDI functionality to create a region, to set the clipping boundary, to draw the (bounding box) border lines and to draw vector duplicates of AutoCAD elements within that bounding box. The resulting EMF file loads into a graphics program (PaintShop Pro 8) for further processing and conversion to a raster image.
The resulting vector images of the elements overlap "dead on" the test images (TIFF) created from screen shots but the viewing window (bounding box) changes its preset size to a smaller one. (Using the "canvas" function, I can resize the windows to its original size without loss of any data or precision.) So far, I could not find where the problem lies that the EMF generated image window is smaller than the preset clipping region.
Here is the skeleton of my code:
HRGN clipReg; // output region
int width; // width of output
int height; // height of output
HDC hdcEMF; // metafile data
HENHMETAFILE hemf; // enhanced metafile
clipReg = CreateRectRgn( 0, 0, width, height ); // int width = 2000, int height = 1500
int ires = SelectClipRgn( hdcEMF, clipReg); // to clip the vectors drawn within the 2000/1500 bounding box
//draw elements
ires = outBoundRect(); // border lines (rectangular bounding box 0/2000/1500)
ires = drawOutput();
// close EMF
SelectObject(hdcEMF, m_oldPen);
SelectObject(hdcEMF, m_oldBrush);
hemf = CloseEnhMetaFile (hdcEMF);
When I open the resulting EMF file, the PhotoShop reports a window size (canvass) of 1924 / 1443 instead of the (to be expected) 2000 by 1500? Can anynone out there help me to resolve this?
Thanks a lot,
Tomas

Hello All,
Is there a way to configure Visual Studio to use GCC or other compilers to generate native programs for devices with ARM9 processors. Anything is welcome, application wizard, project sample, add-in or a paper fragment containing the secrets of the universe.

Hello, im having a problem creating a dialog from another dialog box, as of now, i create, initilize, and display the new page using:
void CDisplayPage::LoadPattern()<br />
{<br />
if( m_LoadPattern->GetSafeHwnd() == 0 )<br />
m_LoadPattern->Create();<br />
<br />
m_LoadPattern->OnInitDialog();<br />
m_LoadPattern->ShowWindow(SW_SHOW);<br />
}
where m_LoadPattern is an instance of the dialog i want to display. For the most part this works, it seems to create and paste the dialog, but when i got to use the box, it seems like its just a background imagine, and things from the calling dialog then pop up, in other words, it seems to be painted, but it can't be the active window for some reason... I can post more code, but hoping its a simplier problem than that. Thanks.

never call OnInitDialog() yourself ! it is called automatically by the MFC framework !
moreover, what about doing simply this :
CMyDialogType dlg;
dlg.DoModal();

well, if he wants a modeless dialog, he will do a Create and a ShowWindow.

Yes very useful indeed. I did find the problem though, it had to do with the style parameters in the resource file, im not sure which one was messing it up, cause i just used copied the same param's from another dialog that was working.

I am almost sure that your dialog's Border was not set to Dialog Frame in Properties Dialog.

I'm pretty sure it was the DS_MODALFRAME option... It looks like the same thing your talking about, without looking at what this option does.

Could some one help me with dynamically creating a combo box at a particular position. Currently I have a text Box, I need to replace this text box with a combo Box.
Any help will be greatly appreciated.

you could create both with the resource editor, and at initialization time of the program, hide on of the two using CWnd::ShowWindow(SW_HIDE).
d'you follow me ?

I have done this (drop-down list boxes) in C, SDK-level stuff. Is this any use, or are you looking for this new-fangled C++, MFC, etc code?

Hey,
I use a CRichEditCtrl to display RTF-text on screen and later to a printer. My code works pretty good for "printer - output" but on screen output my text is moved (ca. 2cm).
Can you help me solving this problem?

Hello !
I need to 'compute' a random __int64 value that must be included between two values (both are __int64 too).
Any idea how I can manage that ? I don't think it exists something else than rand_s() function that will 'return' a random unsigned int.
I'm trying to find how I can manage to do that by simply using this function several times but it's the end of the day and my brain is too slow yet 
Any idea ?

__int64 i64 = (__int64)rand() * (__int64)rand();
