Why don't you try to open the database connection in a database gui tool, and see what happens?
You might get interesting information about the problem that way.
Just a thought...

I am trying to work with icons in the system tray and on the title bar and the resource editor from the 6.0 suite. I can only create bitmaps or icons with 256 colors. Is there any way that I could create an SVG file or PNG/JPG and use those for the icons?

Now, I have VS .NET 2002 so I'm not sure this works for you. I recently started working with CTreeCtrl's and I needed two custom icons. I created them in MS Paint, saved as 16x16 24-bit bitmaps. I imported them into my project via the resource view, they showed up under the category "Bitmaps", one called IDB_FILE and another called IDB_FOLDER. For the CTreeCtrl, to use icons, I have to load up a CImageList data type with my images, then attach it to the CTreeCtrl. This is the resulting code in regards to the CImageList, I don't know how helpful it was but it did the job fine for me:
m_images.Create(16, 16, ILC_COLOR24 | ILC_MASK, 0, 2);<br />
<br />
CBitmap folder;<br />
ASSERT(folder.LoadBitmap(IDB_FOLDER));<br />
ASSERT(m_images.Add(&folder, RGB(0, 255, 128)) != -1);<br />
<br />
CBitmap file;<br />
ASSERT(file.LoadBitmap(IDB_FILE));<br />
ASSERT(m_images.Add(&file, RGB(0, 255, 128)) != -1);<br />
<br />
m_tree.SetImageList(&m_images, TVSIL_NORMAL);
Note, m_images is the CImageList and m_tree is the CTreeCtrl.
I also implemented a mask so the background of the control can be changed and the icons' picture will change appropriately. I painted the RGB color 0, 255, 128 on the image where I want transparency then on the Add() command, I specify what color the mask color is. Again, I don't know how helpful this is to your project but good luck.

Thank you for the response. Unfortunately though, when I import anything more than 256 colors, it gets converted to 256 colors. Please note that I believe this is a limitation of Visual C++ 6.0 and its resource editor. I am assuming that I will have to load the icon from code somehow and just link everything externally via files. I could be wrong, but this is why I am here

AFAIK, you couldn't be able to use HIGH res Icon in Visual C++ 6.0

You can't use hi-res images from within VC6. You need to create them using another application and then modify the RC file manually.

Hi I’ve been trying to write a routine that will scan 1 bitmap to see if a second bitmap is within it. I’m not having a problem with the algorithm to do the search I’m having problems getting the pixel colors from both the bitmaps. For testing I loaded the first image by calling ::LoadImage() which returns an HBITMAP. For the second image I’m loading into I.E. and using some code to get the hwnd and pull the HBITMAP calling CopyWindowToBitmap().
So now that I have 2 variables of type HBITMAP. How do I get there pixels?
This is what I’ve tried with no success.
HBITMAP bmpOne;
HBITMAP bmpTwo;
… Some code to get bmpOne and bmpTwo ..
HDC hDC = ::GetDC(NULL);
HDC hDCBMPOne = ::CreateCompatibleDC(hDC);
HDC hDCBMPTwo = ::CreateCompatibleDC(hDC);
::SelectObject(hDCBMP1 , bmpOne);
::SelectObject(hDCBMP2 , bmpTwo);
COLORREF PixelOne;
COLORREF dPixelTwo;
PixelOne = ::GetPixel(hDCBMPOne, x, y);
PixelTwo = ::GetPixel(hDCBMPTwo, x, y);
If I do the following…
int red = GetRValue(PixelOne);
int green = GetGValue(PixelOne);
int blue = GetBValue(PixelOne);
Even though the color at x,y is not white I always get
red = 255, green= 255 and blue = 255;
I know that the HBITMAP bmpOne and bmpTwo are loaded because I display them in a dialog.
Any thoughts? Is there a way to get the pixel data directly from HBITMAP? Thanks.

I think you can do this by select the bitmap(s) into a device context (one at a time) and then calling GetPixel()[^].

GetPixel is terribly slow, can you create a HBITMAP so that it's also a DIBSECTION ? Then you'll have a pointer to the underlying bytes for this sort of work.

I second that. GetPixel() is horribly slow! The only downside with dibsections is that you'd have to take bitdepths into consideration. A small price to pay for good performance though.

I have a class called CFileObject derived from CObject and a class called CFileTree derived from CObList. At a particular point in my program, I have an if statement that tests if an object (could be a CFileObject or CFileTree) is a CFileObject. At a point in the execution, the object is a CFileTree but when it runs the test, it returns true, saying it's a CFileObject which is incorrect. Do I need to declare my two types as being the types that they are so IsKindOf() can resolve properly?

From the MSDN documentation[^]:
"This function works only for classes declared with the DECLARE_DYNAMIC, DECLARE_DYNCREATE, or DECLARE_SERIAL macro. Do not use this function extensively because it defeats the C++ polymorphism feature. Use virtual functions instead."

You could try using dynamic_cast instead. But as Ravi said, it's not good OO practice.

hi
you can use the CString constructor to do this
CString strInfo(IDS_INFO);
or the Format method of CString if the reseource string needs additional paramaters
like this:
CString strHelloWorld;<br />
strHelloWorld.Format(IDS_HELLO, "world");
Regards

You can also use AfxFormatString1 & AfxFormatString2
if your resource HELLO_ID is: "Hello %1"
you can do:
CString result;
AfxFormatString1(result HELLO_ID, "World");
it gives u Hello World

Hmm... seems like it won't work:
---------------------------
#include <afx.h>
#include "stdafx.h"
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
CString errors;
errors.LoadString(IDS_ERROR1);
MessageBox(NULL, errors, "Hello", MB_OK);
return 0;
}
---------------------------
Errors:
---------------------------
C:\VCProjs\KixWTF\KixWTF.cpp(14) : error C2065: 'CString' : undeclared identifier
C:\VCProjs\KixWTF\KixWTF.cpp(14) : error C2146: syntax error : missing ';' before identifier 'errors'
C:\VCProjs\KixWTF\KixWTF.cpp(14) : error C2065: 'errors' : undeclared identifier
C:\VCProjs\KixWTF\KixWTF.cpp(16) : error C2228: left of '.LoadStringA' must have class/struct/union type
C:\VCProjs\KixWTF\KixWTF.cpp(16) : error C2065: 'IDS_ERROR1' : undeclared identifier
---------------------------
Anyone know? 
Thanks!

I assumed you were building an MFC app. Here's[^] a link to the Win32 version of the API.

Create an MFC dialog based application and don't create the dialog in your app's InitInstance() method. Instead, just execute whatever (non-GUI) code you wish to call. Note, your app will exit when it returns from InitInstance().
Hope this helps!
