Check your link. I suppose it is a warning telling us that there is no image available but there is only chinese characters.
|
|
|
|
|
Sorry.
But the image is there.

I have some chinese letters and a "prohibited" symbol.
BTW, a GUI can be done in a few minutes or in days. It directly depends on what you want to do. Just asking "How much time need a GUI?" is no sense sorry.

Hi,
There are certain sub-classes that I use often in many projects. For example CMyDialog, CMyFormView... Each time I have to use CMyDialog instead of CDialog I have to rename CDialog to CMyDialog in the .cpp and .h files.
Is there any way to add CMyDialog, CMyFormView to the list of base classes so that this derivation is done automatically while creating a new dialog/formView class?
Thanks.

I don't know if there is a way, but I guess is not a good idea to go into the core of the MFC and modify things.
I personally find the CTRL+H (search and replace all) very usefull for that moment, and is just a few seconds.

Hi, I need help with a C++ Win32 GDI project I am working on in both Bloodshed Dev C++ and Visual C++ 6.0 and Up in Windows XP SP2.
What my program does is moves a ball (circle) arround the screen corresponding to arrow keys, and a fixed cross that reappears as the ball passes over it. The problem is that when I do the BitBlt, it draws a square instead of a circle, so a square is overwriting the cross (basically, a circle with a white square region around it. Is there a way to do this BitBlt with just the circle and not the square because this is annoying. In other words, I don't want a square region overwriting the cross - just the circle.
Here is what I have so far:

Did you try it with a CRgn or HREGION ?

usually a well chosen raster operation (such us SRCPAINT, instead of SRCCOPY) does the trick (of course you have to choose bitmap colors accordingly)
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

You can use the TransparentBlt[^] for that operation. Simply specify the color that shouldn't be visible from your source bitmap (in your case, it will be white).

I am trying to extract cell contents from an excel spreadsheet into a VS6 C++ application. I am using a CRecordset object set up with an ODBC datasource to my spreadsheet. My problem is that some of the cells contain text with formatting such as bold and italics. I need this formatting to be preserved but unfortunately my m_RecordSet.GetFieldValue() calls are only pulling over the plain text.
Is there a way of preserving the formatting and what form would it be in? RTF?

Hi,
Yesterday I made my first Project Wizard and it's working like a charm!! Now there is a little feature I'd like to add:
- All the project is based on classes derivated from GameState class
- The current wizard creates a GameState derivated class as a start
- I need to put a wizard in the Add Item box, so the programer can add a new derivated class if he wants to create another game state. (It should create the .cpp and .h files). This wizard should also shows a screen so the programer choose between the game states I provide.
Thanks,
Dirso

hai all,
here iam facing some problem with deletefile.
it goes like this,
1.if i create a file using windows(rightclick>new>text document) and delete it through code then it is working.
2.if i create a file using FILE *fp;
and try to delete it, then it is unable to delete it.
iam unable to analyse any more on it.
please give your ideas and different possibilities to solve the problem.
or if any body can suggest any other technique, which works, it would be appreciable.

Are you closing the created/opened file before trying to delete it?

YES iam closing the files(fclose).
and more over, the files were created in previous sessions. not in the session where iam trying to delete them.
and my files have the extension .cry does it matter?
here are some case studies.
1.iam trying to delete the s1.cry(created by my application) like this
filename="s1.cry";
DeleteFile(rootpath+"\\cryfiles\\"+filename);
RESULT : no use.
2.now i rename it through windows like s1.cry1 and
filename="s1.cry1";
DeleteFile(rootpath+"\\cryfiles\\"+filename);
RESULT : successful.
any ideas?

I make it like follows:
void CMyView::OtherFunction ()
{
char FileName[MAX_PATH];
GetModuleFileName(NULL, FileName, MAX_PATH);
m_szOfflineName = FileName;
m_szOfflineName = m_szOfflineName.Left(m_szOfflineName.ReverseFind('\\'));
m_szOfflineName += "\\OfflinePCode.pc";
}
.
.
void CMyView::OnDestroy()
{ CFormView::OnDestroy();
CFile f;
if (f.Open (m_szOfflineName, CFile::modeRead))
{ f.Close ();
f.Remove (m_szOfflineName);
}
}
But I am in MFC, I dont know if u can use the CFile

even this logic didnot work for me.
but this gave me some clue to proceed further.
if it works out i shall share the problem and the solution here with you.
thanks a lot.

|
|
|
|
and by the way Nelek,
could you solve the scroll bar dialog problem?
thank you.
|
|
|
|

To be honest... I have not tried more than what I told you. Im in a new project and my time for VC++ is limited. I will take a look this weekend at home. But it actually won't be so easy. I can not simulate your problem, my scrolls are working ok.
