Are these messsages being received by the application?

No.

You've completely ignored the LPARAM when sendig the WM_KEYDOWN message.

Then how do you know if the problem is with the way you are sending the message, or the way the message is being received? Knowing that much would eliminate 50% of the possibilities.

How to programatically change the User Locale?
In the NLS documentation it is mentioned that it is not possible, is there any way around for this?
Thanks!

Thanks but this is not enough. Frown | :(

setLocale() is specific to the current program, I need to modify User Local which we modify through the Control Panel --> Regional and Language Options --> Regional Settings.

One way I found out is modifying the registry at the following location HKEY_CURRENT_USER --> Control Panel --> International --> Locale

But I need an elegent solution.

It helps to specify all of your requirements up front.

Yes, but the MSDN documentation also refers it as User Locale.

hi,
I have a msflexgrid with 2 columns and 25 rows(all with data in it) in my dialog.i'm also having a edit box in the same dialog above the flex grid.now wat i want is..if i type a name or a letter in the edit box the mouse pointer should go to that row that contains the name.

for example if i hav 2 colums(name and rollno)in msflexgrid
if i type "A" in the edit box,thn the mouse cursor should go to the row where that name column contains first letter as "A".Is there any function for getting the mouse pointer to our flexgrid?

iam not sure, weather you can take your mouse pointer or current focus to the required cell, but you can select the required cell and also set its color.
if you are stuck up in searching the item, then,
you have to initialise the loop and search every item, and see if any letter has the starting digit A (for example).
any more guidance required?
you are welcome.
good luck.

There is no way other than loading the pngs and then convert them to a (device-dependent) CBitmap, I fear.

Let's think the unthinkable, let's do the undoable, let's prepare to grapple with the ineffable itself, and see if we may not eff it after all.

You can read png files and then convert to CBitmap for use on the toolbars.

Thats probably not possible. At least not out of the box.
Here[^] are some buttons allowing transparency.
And here[^] is an example of a toolbar with background-bitmap.

Not able to add Item in Combo Box [modified]

Hello Friends,

I am using WIN32 Dialog based Application. And in that I am using combo box. But not able to add the string in the combo box.

the Code I use to set the text in dialog box in as follows

case WM_INITDIALOG:
TCHAR *ValueName = new TCHAR[20];
wcscpy(ValueName,L"Gaurang ");
hCombo = GetDlgItem(hWndDlg,IDC_COMBO1);
SendDlgItemMessage(hWndDlg,IDC_COMBO1,(UINT)CB_ADDSTRING,(WPARAM)0,(LPARAM)L"Gaurang");
dError = GetLastError(); //dError  = 1460
LRESULT lr = SendMessage(hCombo,(UINT)CB_ADDSTRING,(WPARAM)0,(LPARAM)L"ValueName");
dError = GetLastError();  //dError = 1460
break;

When I use the above line of code to set the Text in combo box it gives me the 1460 error code which says "This operation returned because the timeout period expired"

Are you sure that combobox is created with the same ID?

Also can you do this from anyother event than WM_INITDIALOG? I mean any WM_LBUTTONDOWN?

Hi,

When I use the above code in some Button even then I am getting Error code as 5.

I.e.

case WM_COMMAND:
if (LOWORD(wParam) == IDOK)
{
SendMessage(GetDlgItem(hWndDlg,IDC_COMBO1),(UINT)CB_ADDSTRING,(WPARAM)0,(LPARAM)L"ValueName");
dError = GetLastError(); //dError = 5; which mean Access denied
}

I am using this code in Modeless Dialog Box. Can it be the source of problem ? This is what I am getting.

lr=  SendMessage(hCombo,(UINT)CB_ADDSTRING,(WPARAM)0,(LPARAM)ValueName); //lr ==0
  dError = GetLastError();  // dError == 1460
 lr=  SendMessage(hCombo,(UINT)CB_ADDSTRING,(WPARAM)0,(LPARAM)ValueName); // l2 == 0
dError = GetLastError();  // dError == 1460
 lr=  SendMessage(hCombo,(UINT)CB_ADDSTRING,(WPARAM)0,(LPARAM)ValueName); //lr == 0
dError = GetLastError();  // dError == 1460
lr=  SendMessage(hCombo,(UINT)CB_GETCOUNT,(WPARAM)0,(LPARAM)0); //lr == 3
dError = GetLastError();  // dError == 1460

I got the problem... Smile | :)

CB_ADDSTRING has no effect on last error.

Try like this and you will get the answer...

SetLastError( 10 );
SendDlgItemMessage( hDlg, IDC_COMBO1, CB_ADDSTRING, 0, (LPARAM)L"Apple" );
