I used LoadImage as follows . But still image is not displayed . I checked the values returned by functions used
All functions return successful values. Do we need to set any properties of the list control?
m_imageList.Create(32, 32, 0, 1, 1);
HANDLE hIcon1 ;
hIcon1 = LoadImage( AfxGetInstanceHandle() , LPCTSTR ("IDR_MAINFRAME"), IMAGE_ICON , 32, 32,LR_DEFAULTSIZE);
m_imageList.Add((HICON)hIcon1);
pList->SetImageList(&m_imageList, LVSIL_NORMAL);

I checked handle returned by loadimage . It returns NULL. I tried using GetLastError BUt it is returning zero .How to use LoadImage?

Here 's the code I use to set an ImageList to a CTreeCtrl, it works similar
as with an CTreeCtrl. I use a bitmap and a derived CTreeCtrl class though.
void C3StateTree::PreSubclassWindow()
{
<pre>
m_ImageList.Create(16, 16, ILC_COLOR4, 24, 0);
CBitmap nBitmap;
nBitmap.LoadBitmap(IDB_TREESTATES);
m_ImageList.Add(&nBitmap, RGB(255, 0, 255));
SetImageList(&m_ImageList, TVSIL_NORMAL);
ModifyStyle(0, TVS_CHECKBOXES);
ModifyStyleEx(TVS_FULLROWSELECT, 0);
m_Font.CreatePointFont(110, "Courier New");
SetFont(&m_Font);
m_hInsertAllowed = LoadCursor(AfxGetResourceHandle(), MAKEINTRESOURCE(IDC_ADD));
m_hArrow = LoadCursor(NULL, IDC_ARROW);
m_hNo = LoadCursor(NULL, IDC_NO);
CTreeCtrl::PreSubclassWindow();
}

www.lcdstudio.com is a driver for REAL LCD Displays...??!
what want you to do?  I have no idea how to handle a real LCD, but I habe a control for moving around boxes with the mouse.
|

So you want a virtual LCD on your desktop?
You can make a window look like a LCD and use rect's as pixels. Fill them with a color for turing on and off...
hope this helps.

Urm  sorry for that...
Is there any way you can trace wich pixels are turned on and trace the image or someting?

What I mean with trace is: If you click on an image, you can somehow select that image or determine how it looks like...

I am trying to create a bitmap during runtime. I would like to use an RGB color to create a bitmap (15x16) of just that color.
I tryed this code:
HDC dc= CreateCompatibleDC(NULL);
BITMAPINFO i;
ZeroMemory( &i.bmiHeader, sizeof(BITMAPINFOHEADER) );
i.bmiHeader.biWidth=16; // Set size you need
i.bmiHeader.biHeight=15; // Set size you need
i.bmiHeader.biPlanes=1;
i.bmiHeader.biBitCount=32; // Can be 8, 16, 32 bpp or other number
i.bmiHeader.biSize=sizeof(BITMAPINFOHEADER);
VOID *pvBits;
HBITMAP hbmp= CreateDIBSection( dc,
&i,
DIB_RGB_COLORS,
&pvBits,
NULL,
0 );
HBITMAP oldBmp= (HBITMAP) SelectObject(dc,hbmp);
RECT rect= {0,0,16,15};
FillRect(dc, &rect, (HBRUSH) Currentcolor);
but i got always black rectangle (not color).
Please help me.

You must create compatible DC from the real context.
Just add next lines
HDC hdc= ::GetDC(NULL);
HDC dc = ::CreateCompatibleDC(hdc);
<span class=cpp-comment>
::DeleteDC(dc);
::ReleaseDC(hdc);
That's all

I used SQL Server 2000 created a data source.Then I put it on to my homepage.Although The server support SQL Server DataBase,but it is impossible for him to run a srever App for my Client App.So I must use my ID and Password connect to it directly from my Client App.Also I want it to work very smoothly no matter where my Client App runs . How can I do this on VC6?

Hi,
Help me please with the following:
I created an application,
and added a dialog box to that,
and, in the dialog box there are edit boxes, and I can't manage the following: when I press the OK Button I want to check if there are any empty edit boxes, and if there are, not to closing the dialog box go to that edit box?
Thanx.
|
|

Are you using a class library? If you're using MFC (just guessing), you do your checks in OnOK(). If the data doesn't pass your checks, just don't call CDialog::OnOK()

Thanx for your quick reply.
Yeah, that was really silly question.
I should know that.

Oh, one more thing
how that is done with tabbed dialog boxes?
I did that in single dialog box, works fine, but in the tabbed dialog boxes i cant manage.
thanx.
|
|
|
|
|
|
well,
for Cancel button I need nothing,
what I need is when the OK button pressed, to check if the Edit Box is Empty, if it is empty, not closing the dialog (Tabbed) Box, go set the Focus to that Edit Box.
I managed to check the Edit, but the Dialog (tabbed) Box closes.
I do not press te Cancel Button.

You need to do validation in the page's OnKillActive() function. Returning FALSE will keep the user from switching to the other tab(s). Also, When the OK button is clicked, OnKillActive() is called first to see if it is ok to proceed. Set breakpoints in these two methods to see how things work.

Do not allow the OK button to be clicked until ALL controls contain valid data. Your users will be very annoyed that the OK button is allowed to be clicked when there is invalid data; this violates the basic principles of GUI design.

How can I disallow the OK button in tabbed dialog box?
|
|
|
|
|
It was not meant to be "disallowed." See my reply about OnKillActive().

Hello,
I've been out of the MFC world for about a year. Do y'all recommend upgrading to VC++.net from 6.0? Reasons?
thanks!

The compiler and standard library are much better.
The IDE is different - some people like it some don't.
If you are just using MFC then I wouldn't bother.
