It makes compiling more efficient because if you had everything in the .h file everytime you modified one function you would have to recompile the entire application. Using the header files you can link code together and build an application across multiple files. header files also are needed when working with libraries.

does anybody know how to find a word in a string?
for example I want to find the word "test" in the string "This is a test"...
Is String.Find(... the right way?
|
|
|
|
|
yeah, CString::Find will return the position where "test" begins (10, I think), or -1 if it's not in the string.

You can use strstr()
char str_to_find[] = "test";
char *pdest;
int result;
pdest = strstr( your_string, str_to_find );
result = pdest - you_string + 1;
if( pdest != NULL )
printf( "%s found at position %d\n\n", str_to_find, result );
else
printf( "%s not found\n", str );
I more or less just copied the code from the MSDN.
OR you can use the MFC-function Find()
int res = string.Find("test")
"string" needs to be from type CString
hope this helps

If you're using MFC's CString, use this:
CString myString = "This is a test...";
int pos = myString.Find("test");
if (pos == -1)
{
// string not found
}
else
{
// string found
}
If you're using Standard C++, use this, check out the strstr() function.

Does anybody know how to make a tree controled options dialog, without mfc? Like the one in winamp? with a tree on the left that changes the dialog layout on the right with each selection... do they use property sheets? i've read the articles on this... but i don't want to use MFC! my app is written entirely in pure win32 api from the platform sdk.
thanks,
john

You start by making several modeless, borderless dialogs. When the selection in the tree changes, show the one dialog that corresponds to the selected tree node.
The techniques in the MFC articles are applicable to you. Don't dismiss them just because they use MFC.

Any ideas why the compiler is telling me it doesn't recognize the ID of the dialog that VC++ just created? I mean, I just made the resource for "IDD_DIALOG1", then created a new class for it, and when I try to build that class has an error in the generated .h file, at the line: enum { IDD = IDD_DIALOG1 } saying the ID is an undeclared identifier. that's lame. any ideas how to get rid of this?
thanks,
Jake

Check if in the resource.h header file you have that ID.
And if in the header of your Dlg class you have the include of the resource.h
Cheers!!!!

The ID's are in resource.h, which is included only in my CWinApp-derived class. The app's header is included automatically in every cpp file in the project. So, when I compile the class in question, it picks up the include and works fine, but when I build the project, it apparently looks at the headers first and gives me trouble. should i include the app's header in the problem header, instead of in it's cpp file?
|
|
|
|
|
First. Try to include the header in the header of the class dialog.
Second. Check if the value of IDD_DIALOG1 is correct, or if is dupplicated.
If the problem persist, try to sen me the project by mail.
Good luck!!!!

I am using a printer outside the Framework.
I declare a variable to hold a RecordSet Field:
CString m_MyCString;
I set the variable to the record set field:
m_MyCString = m_pSet->m_MyStringField.
All is OK so far.
After I start the document:
if (pDC.StartDoc(&pMyDoc)>0)
{
etc.
}
the CString variable m_MyCString gets changed to a different value.
Duh!!

He also has to make it owner draw too, doesn't he?

Have no idea - it depends how Windows draws items in the listbox. If DC has no TRANSPARENT bkmode set, he'll have to go ownerdraw.
The easiest solution would be switching to CListCtrl and using CListCtrl::SetBkColor and CListCtrl::SetTextBkColor.

I've got an very urgent question.
I want to get the Serialnumber of a Disk (Floppy Disk, Hard Disk (IDE &
SCSI), CD,...) into a CString (- the disk where my program is saved).
I've only found Source Code for IDE Hard Disks.
Is there an API function to get the number.
(There is one in VB.)

Does anybody know how to insert a new line
into a CRichEditCtrl/View?
for example like this:
rectrl.InsertText("\nnew line\");
thanks in advance
|
|
|
|
|
Use CRichEditCtrl::ReplaceSel. If there is no current selection, the replacement text is inserted at the insertion point, that is, the current caret location.

Can you please tell me what's wrong with this code:
CMyRichEditView *pView;
CRichEditCtrl& pCtrl = pView->GetRichEditCtrl();
pCtrl.ReplaceSel("\r\r\ntest");
I get a debug assertion in the third line.
thanks
|
|
|
|

I've never used a RichEditCtrl before, so I might be wrong, but it looks like you're declaring a pointer and never constructing it, so pCtrl is probably NULL or invalid somehow. Something like that

Yes, it seems to be NULL, by why?
