Hallo,

Does anyone here know an easy way to change the text of the header of a listCtrl. Till now, I delete all columns and insert them with the new text again. But I think, there should be an easier way Smile | :)

Thanks, Gerhard

Use SetColumn.

An Eg:

LVCOLUMN lvCol = { 0 };
lvCol.mask = LVCF_TEXT;
lvCol.pszText = _T( "Nibu babu thomas" );
 
// Change caption of first column
SetColumn( 0, &lvCol );

Thank's for the example - my text is stored in a CString. And with this it doesn't work (conversion to string doesn't help).

But it works with a code like this:

	<br />
char othertext[100];<br />
sprintf(othertext, "%s", text);<br />
lvc.pszText = othertext;<br />

Am I crazy to do so???? Unsure | :~

Yes!!

What about...

lvc.pszText = text;

Either way text is a string right?

Well if you have want to have strings that contain number then it's quite ok...

sprintf( othertext, "Column number: %d", 1 );
lvc.pszText = othertext;

Maybe my part of code was too short Confused | :confused:

so I send the whole loop

	<br />
  LVCOLUMN lvc;<br />
	CString titel;<br />
	int i = 3;<br />
	if (kstkaranz->wdfirst())<br />
		do<br />
		{<br />
			i++;<br />
			titel = kstkaranz->wdgetkstnr() + "\n";<br />
			titel = titel + gettitel(0, kstkaranz->wdgetdatenart(), kstkaranz->wdgetvon(), kstkaranz->wdgetbis());<br />
			listCtrl.GetColumn(i, &lvc);<br />
	char strbetrag[100];<br />
<br />
	sprintf(strbetrag, "%s", titel);<br />
			lvc.pszText = strbetrag;<br />
			listCtrl.SetColumn(i, &lvc);<br />
		}<br />
		while(kstkaranz->wdnext());<br />

where kstkaranz->wdgetkstnr = something like "6984" (number of a cost center) and the result of gettitle is something like " PLAN VALUES 2007-01-01 - 2007-02-28'. The whole result in titel is a CString (with numbers, of course, but handled as CString).

Btw, it works fine and as there should be no difference, whatever the CString titel contains, I see no danger. But your posting made me consider ....??

Btw2: if I try "lvc.pszText = titel;" I get an error-message like (I try to translate): Binary operator: no operator defined who accepts a right-sided operator of type 'class CString' Dead | X|

Your code is fine. But your code snippet made me say that.

There is no point in sprintfING another string into another string. Since we already have a string it should be fine.

You can assign a CString object into lvc.pszText, do this...

lvc.pszText =  titlel.GetBuffer(0);<br />
// Dont' forget to call ReleaseBuffer<br />
titlel.ReleaseBuffer();

Hey, this seems to become a fine weekend. I'm just having breakfase (it's 8:00 here), want to read some newspapers in the internet - and the first when I look on my monitor is your message. Of course I tried suddenly and it works!

Btw - with ' 'why I'm wrong ' I wanted to say 'why I made something wrong in my code'. My english Blush | :O

So, many thanks and have a nice weekend too

The reason is you could have used "title" directly instead of trasferring it into another string. Does such a copy satisfy any purpose.

None AFAIK. It will be a performance hit. It's redundant that's why I said you are wrong.

I said that from your code snippet.

Look at the following example...

char title1[100];
sprintf( title, "%s", aString );

What's the point in doing this!!!. Since aString is already a string why not directly assign that string in a proper way and also on the long run this could be a performance hit.
