I am using the RegQueryValueEx() Function to fethch the value from the reggistry I set previously.

But getting porblem. It fetches only first charcter only.It Show the Corrent size of the Value but Fail to Fetch the Whole String.Previously I was using the RegQueryValue() and It is working Fine Smile | :)

. But I need to use RegQueryValueEx() as I have to fetch Other valued in addition with default. Frown | :(

The Code I am using is as follow.

RegOpenKey(HKEY_CURRENT_USER,L"Software\\PersonalMenu",&hKey);<br />
Code= RegQueryValueEx(hKey,L"JAVA",0,&Type,NULL,&size);<br />
 BYTE *Data = new BYTE[size];<br />
Code= RegQueryValueEx(hKey,L"JAVA",0,&Type,(BYTE *)Data,&size);	<br />

I dont know what is the problem with it. If it is showing the Correct size of the Value don't it also show the Value.

Do you have a unicode project setting but not viewing the string as unicode ? This would explain that you would see the first character.

Are you getting a string value into a BYTE array?

If so, how are you examining the string? Intellisense may only show you the first byte.

those are the debug versions of the C/MFC runtimes, but you're apparently doing a release build. you can't mix debug and release builds like that.

if you're linking to a static library, make sure you're linking to the release build of the library for release builds of your EXE

Problem with Combo Box

GauranG Shah14-Sep-07 23:27

14-Sep-07 23:27

I am Using Win32 Dialog based Application. And trying to add the string in Combo Box as runtime with following code.

HWND hComboBox = GetDlgItem(hWndDlg,IDC_NameCombo);<br />
LRESULT lr =  SendMessage (hComboBox,CB_ADDSTRING, 0, (LPARAM)L"Item 1 ") ;<br />

But nothing is added in ComboBox. I checked the lr Value and it show 0. I.e. Operation Completed Successfully.

if you know please tell me what is the problem.

Thnx in Advance.

WM_INITDIALOG But it is still not working

The Value of Combo Box Handle (hComboBox) is 0x002804c2

how to change the font caption of button

15-Sep-07 11:54

GauranG033But nothing is added in ComboBox.

There is a difference between nothing being added vs. not being able to see the added item. Since SendMessage() returned 0, the item was added.

File + folder names proessing APIs

14-Sep-07 20:57

Hey guys , I vaguely remember an API like GetFilePath, that gives you the directory path of a file when you pass the complete file path. like

c:\windows\temp.txt ------>> c:\windows\

You remember that one? And there were also many functions like that to process the "\" "/" like that and to get root folder and many more things. damn nothing strikes for me now. I stronly remember I found them in MSDN, but couldn't spot any of them now. Please help!

I tried a hundred time "Shell" + api + path and all combination, I got all craps. The worst crap was the page that took me to "Shell("mspaint.exe")" .. A vb function just like createProcess. OMG | :OMG:

Anyway I'm so happy I've found the exact page in MSDN Jig | [Dance]

Yup, I was just trying to spot this guy, found and used it here[^].

Btw David, I have a simple question related to above, If you want to clear a char buffer[] (stack allocated) , what's the proper way?
like :

char szTemp[256];

<br />
strcpy(szTemp,"");<br />
*szTemp = 0;<br />
ZeroMemory(..)<br />
Memset(..)<br />
*szTemp = NULL;<br />
