Why shouldn't it? Try this:

CString str;<br />
m_valueSearchBox.GetWindowText(str);<br />
int nPos = str.GetLength();<br />
m_valueSearchBox.SetSel(nPos, nPos, TRUE);

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

tnx for the reply, but I'm afraid I must dissapoint you.
I do this:

<br />
int pos = initValue.GetLength();<br />
m_valueSearchBox.SetWindowText(initValue);<br />
m_valueSearchBox.SetSel(pos, pos, TRUE);<br />

(it's SET not GET, but not important).
What happens is that the cursor is behind the text, BUT the text is selected, so if you start typing ... Frown | :(

I think the positions in SelSel are index based, so try:

m_valueSearchBox.SetSel(pos-1, pos-1, TRUE);

tnx for your reply, but I have to disappoint you too.

I tried SetFocus() and SetSel with about every value possible.
SetSel(-1, nPos, FALSE/TRUE); (nPos = length, length-1 ,... as first and/or second parameter etc.)

It just doesn't seem to work.
Normally it should, but maybe it's due to something else (processor or something)

I don't know, I'll keep searching

It must be something other then.

I tried this in a test project:

CString str = _T("Test");<br />
m_cEdit.SetWindowText(str);<br />
int nPos = str.GetLength();<br />
m_cEdit.SetSel(nPos, nPos, TRUE);<br />
m_cEdit.SetFocus();

And it does exactly what you want. "Test" is written into the edit control and the cursor is at the end, nothing is selected.

Maybe check for other things that could influence the selection and focus (UpdateData, returning FALSE in OnInitDialog, and all those things)

The correct answer:

<br />
m_valueSearchBox.SetWindowText(initValue);<br />
int nPos = initValue.GetLength();<br />
m_valueSearchBox.SetSel(nPos, nPos, TRUE);<br />
m_valueSearchBox.SetFocus();<br />
bResult = FALSE;<br />

bResult is returned in OnInitDialog. So you were right.

Huge tnx to you. (and off course all others who tried to help Wink | ;)

How do I load a dll from within a dll.

Hi All, On win2000 I have created an exe file to list and load dll files. Selecting a dll should load an API file, also a dll. LoadLibrary() works in the exe but not in a dll. Can anyone tell me what's wrong?

Not sure. You must be doing something wrong in your DLL, because any DLL could really load another DLL.
When you call the LoadLibrary, what is the return value from GetLastError when the LoadLibrary fails? That is a good clue what is wrong.

My mistake Blake, I should have finished the story.
The .dll API file is in the root directory of D:.
The LoadLibrary("D:\\wrk32.dll")result is picked up by GetLastError() which is 126, file not found.

Just before loading your DLL, add this line of code to your program:
SetErrorMode(0);
That way, when you run your progrma, a dialog box will pop up and you can see which DLL is missing. It will tell you all the places it tried to load the missing DLL.
Make sure to take the call back out before releasing your program.

thats why i specified "online" meaning "located on the internet"

I assumed that if you were running VC++ you would have had the Help installed? But that's not always so.

However, you can also always find an up-to-date Help set, which is a superset of the Visual Studio installed online help, at http://msdn.microsoft.com/library[^].

The macros reference will be in there somewhere. Though I always find the online version of the MSDN Library harder to search than the installed version.

COM newbie - ITaskbarList problem

Kri515-Jun-04 21:35

15-Jun-04 21:35

I just started COM programming and managed to write some small sample programs to use the IActiveDesktop and IShellLink interfaces and their methods; basically i am playing around with things like these for the time being:

<br />
    CoInitialize(NULL);<br />
<br />
    WCHAR   wszWallpaper [MAX_PATH];<br />
    HRESULT hr;<br />
    IActiveDesktop* pIAD;<br />
<br />
<br />
    // using Active Desktop interface<br />
    hr = CoCreateInstance ( CLSID_ActiveDesktop, NULL, CLSCTX_INPROC_SERVER, IID_IActiveDesktop, (void**) &pIAD );<br />
<br />
    if ( SUCCEEDED(hr) )<br />
    {<br />
        // Get the name of the wallpaper file.<br />
        hr = pIAD->GetWallpaper ( wszWallpaper, MAX_PATH, 0 );<br />
<br />
        if ( SUCCEEDED(hr) )<br />
        {<br />
            wcout << L"Wallpaper path is:\n    " << wszWallpaper << endl << endl;<br />
        }<br />
<br />
    }<br />
<br />
  //.... etc<br />

The above compiles correctly and works successfully.

However, when i try to use the ITaskbarList in the same manner, the compiler throws it all up, telling me that ITaskbarList is an undeclared identifier...

Any ideas where i'm getting it all wrong?

Many thanks...

Dynamic creation of controls and getting messages

Hi,
I wanted to create dynamically controls (CButton) on my dialog. They are displayed but don't react. Second problem is that I want to react in the dialog to a click on a button.
The creation of buttons (this -> the dialog containing the buttons)

for (int i = 0; i < 16; i++)
{
pButton = new CButton;
iLeft = (iWidth+iSpace)*i;
pButton->Create(_T(""), WS_CHILD|WS_VISIBLE|BS_RADIOBUTTON,
CRect(iLeft,10,iLeft + iWidth,30), this, WM_USER+i);
}

But now I don't know how to get the message queue of the buttons!

thx & greets

You can either specify an ON_COMMAND_RANGE handler for all of them at once, or add buttons in the resource editor with the desired id, create handlers and them remove the buttons (but not the handlers, of course)

ok thank you!
But what I wanted to know is how to create buttons at runtime.
so the problem is that I cannot set ON_COMMAND_RANGE handler cause I don't know how many buttons there will be. But every button should react the same way!
greets

You can use ON_COMMAND_RANGE anyway, just allow for the max number of buttons.

Hi,
I am Aravind from Chennai.
I saw your comment at code project.com on Volume shadow copy.
I need some information regarding that. Hope you have ideas regarding that. If possible, can you please share them with me? My need is as follows...
I want to take backup of files using volume shadow copy service [VSS] in Windows 2003 server.
I have to use VSS for getting the file difference with their previous versions. So, I have to get the snapshot details from VSS.

So, how to get those details and where those snapshots where stored?

Thanks in advance.
