You have to use some delimiter for adding extra data into each element of the array..like following.
arr[0]="43545" + "," + "mydata";
or use the Append method of the CString for each element.
Knock out 't' from can't,
You can if you think you can

Is it better to link .lib files using a line such as:
#pragma comment(lib,"XXXXXX.lib")
or, should they be linked via the project settings? What are the practical differences to these approaches?
Thanks, -mutty

I think there is no difference regarding the final executable, but I think putting of #pragma comment(lib,"XXXXXX.lib") in your files at least requires less configuration work when you re-use your code in other applications. You will not need to remember each time which external libraries must be used.
For instance, this practice can be seen in the header files supplied with MFC.

Hi:
Does anybody know about this problem?
I have been developing this application for several weeks now. I've created all sorts of dialog boxes and used Class Wizard to create a CDialog based class for each one.
Since late last week, Class Wizard has simply stopped working. I create a dialog resource, double click it to invoke Class Wizard, the window pops up, I fill it out and press "Finish". Nothing happens. It does NOT generate the class files. No error is reported, it just doesn't do anything.
I am at a dead stop here. Is anyone familiar with this problem? Somebody suggested last week that I delete the NCB file. This is Visual Studio 2003. I do not see an NCB file in my project directory. I have tried deleting the ASP file but this has had no effect.
Thanks in advance,
Mark

I don't see a CLW file either. Perhaps that is the problem...

I want to convert a string to LPWSTR to be used in RegOpenKeyEx.
i had been able to do it to the string directly i.e. L"xxx"
but unable to do it using string variable.
how can i do that please help.

If performance is not important, I think the easier alternative way is using of _bstr_t type. You can assign and you can get strings of both types:
_bstr_t s;
s = "abc";
s = L"abc";
char * a = s;
wchar_t * w = s;
So just try ::RegOpenKeyEx(..., _bstr_t(my_non_unicode_string), ...).
Note that you can explicitly stipulate the version of RegOpenKeyEx function when your strings do not correspond to the project configuration settings. Just use RegOpenKeyExA or RegOpenKeyExW according to your needs.

this does not work.. gives error at _bstr_t
please help

The _bstr_t type is defined in comutil.h, so you have to add:
#include <comutil.h>
If this is not enough and you get linker errors, probably you will have to add comsuppw.lib library to project settings (Linker --> Input --> Additional Dependencies).

i tried that and now it is giving me error: unable to convert from standard string to _bstr_t.
LONG retcode = RegOpenKeyEx(HKEY_CLASSES_ROOT,_bstr_t(ext.toStdString()), 0, KEY_ENUMERATE_SUB_KEYS, ®key);
tell me wat should I do. I am working on QT development env.(based on C++)
|
|

I suppose ext.toStdString() returns a std::string. In this case, you should try ext.toStdString().c_str(). Otherwise investigate which kind of value returns toStdString().

Hi,
I am having a problem with the collection class CStringList
In the part below, coded in vc++6, when the program is executen and StrList.AddTail(pStr[i]) is reached, the error 'this program has performed an illigal operation..." comes.
Although while compiling, no error is shown.
Please can you tell me what is going wrong?
<br />
void Cop1::OnAdd() <br />
{<br />
int iCount = 0;<br />
int i;<br />
POSITION p;<br />
<br />
iCount = m_payeeList.GetSelCount();<br />
<br />
if (iCount <= 0) return ;<br />
<br />
int* pItems = new int [iCount];<br />
m_payeeList.GetSelItems(iCount, pItems);<br />
<br />
CStringList StrList;<br />
<br />
char *pStr[10];<br />
<br />
for (i=0;i<iCount; i++)<br />
{<br />
<br />
m_payeeList.GetText(pItems[i], pStr[i]);<br />
StrList.AddTail(pStr[i]);<br />
<br />
}<br />
}<br />
Thanks.

I think instead of
m_payeeList.GetText(pItems[i], pStr[i]);
StrList.AddTail(pStr[i]);
you should try
CString text;
m_payeeList.GetText(pItems[i], text);
StrList.AddTail(text);
Now you do not need pStr, which actually was not initialized.
Hope it helps.

Ah! That works. But I did initialised pStr:
char *pStr[10];
How do I get the string back form the StringList?
The code below is giving error. Is it correct?
POSITION p;<br />
CString s;<br />
s.Format("%s",StrList.GetNext(p)); <br />
AfxMessageBox(s,MB_OK);

I think you missed to initialize p. The following should work:
POSITION p = StrList.GetHeadPosition();
CString s = StrList.GetNext(p);
AfxMessageBox(s,MB_OK);

|
|
Yes! It works! Thanks a billion!

Can I not pass the String list, StrList to a function?
It is not working when I am passing it like usual function.
I get the error 'FillReportList' : cannot convert parameter 1 from 'class CStringList' to 'class CStringList'
FillReportList(StrList);<br />
<br />
FillReportList(CStringList list)<br />
{<br />
}<br />
