Form experimental point of view your code has (at least) a problem.

You probably won't know that, since you apparently are not using the debugger as suggested.

Hello,
Thanks for your answers.
You probably won't know that, since you apparently are not using the debugger as suggested.
How is the debugger to be used ?

Like a debugger, I suppose.
You should reach the offending line, try to understand why it is offending, and so on...
You may also get a better help from us if you give us more details (and the debugger usually help in finding such details).
Moreover 'Debug assertion failure' isn't much informative. Why it is asserting (i.e. what's asserted?)? . You're hiding information.

What do you mean exactly by start ? If you put the loop, your program will never end (well, that seems to be obvious). I don't really understand your question.

How can you see that?
What's the purpose of the experiment (just curiosity)?

No, not on a windows platform. Anyway, even having a resolution of 1msec is not possible because windows is not a real time operating system.

My application is MDI.but we modified the precreatewindow and using as single window applicaiton.
And we transfer to different window using menu or pageup,page down.
For ex,i have 5 pages of graphics window showing some animation and index of all five pages as index window.By clciking the topics in index,the new window will appear and we destroy the prevoius window.I draw the window details in OnDraw().
But now i want some graphics window appear as popup with close button.So i set flag for tht particular window and i set setwindowpos()...But its now flcikering...
I dnt know wat to do...
Code:
Same window:
---------------
///Clciking function in Index page
{
.
.
.
.
if( gpGView->glg_animation[giSchPNo].m_hWnd )
{
gpGView->glg_animation[giSchPNo].DestroyWindow();
giSchPNo = iPanNo - FirstGraph();// - 1;
giSchPNo = giGraphicCnt;
return;
}
Then it goes to Ondraw() and draw the window.
As Popup:
----------
///Clciking function in Index page
if(help==1) ////shown as popup
{
if( gpGView->glg_animation[giSchPNo].m_hWnd )
{
////gpGView->glg_animation[giSchPNo].DestroyWindow();
giSchPNo = iPanNo - FirstGraph();// - 1;
giSchPNo = giGraphicCnt;
return;
}
}
in Ondraw() i add this line
((CGraphView *)(((CMainFrame *)AfxGetMainWnd())->pDisplayedViews[6]))->glg_animation[giSchPNo].SetWindowPos(HWND_TOP,(GetSystemMetrics(SM_CXSCREEN)/2) - (480/2),(GetSystemMetrics(SM_CYSCREEN)/2) - (350/2),505,280,SWP_SHOWWINDOW);

I have developed dialog based application to capture data from a device on RS232 & display those data in VC++ 6.0 frontend. Now i need to print this data in defined format on the printer. May be i need to select the printer & then print the report.This methode would be better as the printer to be used is not finalized yet with this application. I am new to VC++, I am not sure which method would be better to use in VC++.
Could you guide how to proceed about his requirement.

If you're using MFC then you may take advantage of this class [^], also have a look at its inspiring article [^].

Is this related to your previous question?
Anyway have a look at this page [^]. Be warned, multithreading is a rather complex topic.

I could print the data displayed on the frontend...& customized the printout. But when the print command is clicked, it displays as below:
Set Font Arial Size = 8
My name is George Papaioannou _________________________________________________________________
Set Font Arial Size = 9
My name is George Papaioannou
....
and so on...
I want to print the data without line feed. that means printout as below.
Set Font Arial Size = 8 My name is George Papaioannou _________________________________________________________________
Set Font Arial Size = 9 My name is George Papaioannou
i don't know where line feed is given in the print?
snippet:
prt.Print(hFont,"Set Font Arial Size = 8",FORMAT_NORMAL);
prt.Print(hFont,"My name is George Papaioannou",FORMAT_NORMAL);
prt.Line (PS_SOLID);
prt.Print(hFont1,"Set Font Arial Size = 9",FORMAT_NORMAL);
prt.Print(hFont1,"My name is George Papaioannou",FORMAT_NORMAL);
prt.Line (PS_SOLID);
I would need to print the data on the same line as actually i want to print text & variable defined in the frontend.
If its only a text there is no problem But i want to print text & variable together which i am not able to print on the same line.
Pl help.....

If you made sure that you always used TCHAR instead of char then things should not be too difficult. Otherwise, well, you have to replace everything by TCHAR strings. Anyway, this article[^] is very good to get started.

That was a great help and interesting article.
Thanks !!!!!!!!!!

Hai!
I have image data present in an Byte array, the image can be a bitmap, jpg or jp2 image. Now how to paint this byte array on my dialog box as an image?
Thanks!
|

First you have to construct the image from the byte array. You can use CxImage[^].
Try the method:
bool CxImage::Decode(BYTE * buffer, DWORD size, DWORD imagetype)
You can see the demo application from the link. I think that it will help you.

I don't know if posting and reposting again and again will actually do the job...

Is there any direct way to convert it to support UNICODE character set?
