I am not sure what you are asking. When you are using the windows api in 8 bit mode you can only display 240 different colors no matter what palette you try to use. This restriction does not exist if you use full screen directdraw. As in full screen directdraw you can use 254 colors + white + black. In 16 bit mode you have 65K colors so it can and will look better.

So why does RealizePalette() return 256 ?
You mean I should keep the size of my palette under 240 ? This way I will leave the top 16 empty.

hi,
this is my observation , correct me if i am wrong .
I was defining a UDT which consist of a
[uuid(D8B3861A-74C6-11d2-0000-00C04FB17CDB)]
struct _BSSID_INFO
{
BSTR name;
short grade;
//classification type;
VARIANT_BOOL graduate;
};
in the IDL file.
Now when i was compiling with Default Visual Studio IDE Compiler it gave the
following errors :-
error MIDL2072 : inapplicable attribute : [uuid] [ Struct '_BSSID_INFO' ]
error MIDL2072 : inapplicable attribute : [uuid] [ Struct '_BSSID_INFO' (
Parameter 'bssid_info' ) ]
warning MIDL2039 : interface does not conform to [oleautomation] attribute :
[ Parameter 'bssid_info' of Procedure 'get_BSSID_INFO' ( Interface
'ICWiFiMgr' ) ]
but when i compiled with new vesrion of compiler and replaced it with new
MIDL.exe in the bin dir of VS6 it compiled correctly.
Any Inputs

Hi!, my wtl app has a dialog that contains some edit boxes whit the password style, however, when i run the app and i type something in these boxes, instead of getting those nice "black dots" like you do on all XP password-edit boxes, i get some "weird" vertical lines, they kinda look like thick binary OR operators " | ".
any idea of what im doing wrong?
Thanks!

You have to set the right font, I think it was Tahoma, but not 100% sure.

I had the same problem a while back when I added a manifest to a MFC project - the password edit boxes had vertical lines instead of nice round circle characters.
The issue was that the edit control had the wrong font associated with it.
In that project I added the following in the dialogs OnInitDialog() function...
GetDlgItem(IDC_EDIT_PASSWORD)->SetFont( CFont::FromHandle((HFONT)GetStockObject(DEFAULT_GUI_FONT)) );
In WTL, it might* look something like this...
::SendMessage(GetDlgItem(IDC_EDIT_PASSWORD), WM_SETFONT, (WPARAM)AtlGetStockFont(DEFAULT_GUI_FONT), MAKELPARAM(FALSE, 0));
*your mileage may vary

Make sure your dialog font is set to MS Shell Dlg and not MS Sans Serif . The dot thingy in XP is a Unicode character that MS Sans Serif does not contain.

Hi,
i am facing some problem while working with streams in my C++ program using STL
main(){
..
..
char buf[256];
stringstream infLine(buf);
infline<
|
|
|
|
|
Hi. First of all, the line
infline<<string1<<string2<<infline; is a little suspicious. You sure you want to insert infline into itself? Won't you mean the following?
infline<<string1<<string2<<endl; Now with the rest. I guess (only guess since you provide little info) you are trying to postprocess the results inspecting buf , but this is not how stringstream works. When constructing infline , the contents of buf are copied to its internal buffer, so infline won't use buf anymore. If you want to postprocess what's left inside of infline , use the str() member function:
stringstream infline;
infline<<string1<<string2<<endl;
string result=infline.str(); Does this help?

I am trying to develop an NT Service, novice in the field and running into following problems.
Let me simplify all the steps to explain problem i am facing, please let me know if i am doing anything wrong
I create a NT Service using Visual Studio 6 ATL Com wizard without a single line of my own code added here. Only thing i change is remove command from Project/Settings/Custom Build that re-registers the service. After that I compile the project. Let say name of the service is MyService. I use following commands to register and unregister service.
MyService -Service
.. start and stop the service
MyService -Unregserver
after this unregserver command this service goes in "Diabled" mode as shown in SCM and now if i want to re-register the service i can "Service cannot be deleted" message box. To only way to register the service again is to logoff the box.
Since I haven't added any of my code in this test project, there shouldn't be case of any dangling handle.
Any ideas?

hi,
yes, after we delete an NT service the SCM behaves this way. it is true for services created as console app also - not only for ATL NT services. Otherwise one thing we can do is:
Instaed of unregistering the service programaticaly do the following,
1) Close SCM if it is open
2) Go to the service database and directly remove it from there. service databse is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services.
3) Open SCM. Now that service will not be listed there in the SCM with that 'disabled' status.I had done some services around two yr back and i think i solved it this way -i dont remember exactly.

Hi All,
I want to create a Toolbar in a Activex control. Activex Control is being created as a DLL which will be invoked in a HTML page and I am working on Visual C++ 7.1 version.... I am trying with the following code but te toolbar is not getting displayed on the dialog...I am trying out this code in OnInitDialog()...
-------------------------
HWND hWnd;
hWnd = CFrameWindowImplBase<atl::cwindow, atl::cframewintraits="">::CreateSimpleToolBarCtrl(m_hWnd, IDR_MARKUPTOOLBAR,
FALSE, dStyle);
CFrameWindowImplBase<atl::cwindow, atl::cframewintraits=""> *myFrame = new CFrameWindowImplBase<atl::cwindow, atl::cframewintraits="">;
myFrame->Attach(hWnd);
if(hWnd)
MessageBox("Working");
--------------------------------------------------
Can any one suggest me what is wrong or any other way to do the same....

Do anybody know a convenient way to compare a variant string to constant string?
VARIANT varName;
VariantInit(&varName);
// varName is given a string value here
// Now I want to find out if the string contained in varName equals to a const string
VariantClear(&varName);
Thanks
|
|

A VARIANT that holds a string has the type VT_BSTR , you can compare a BSTR with wcscmp() :
if ( 0 == wcscmp ( varName.bstrVal, L"some string" ) )
{ }

Hi can we use the .NET assemblies in ATL.
Regards

Blue Pill or Red Pill........??

If a .NET assembly is registered for COM interop (using regasm , the facilities from Windows Installer, or using the appropriate option in VS.NET), you can use it in the same way as any other COM object.
Stability. What an interesting concept. -- Chris Maunder

Hi,
I am new in web services programming.
I followed a sample. It seems worked on my local computer (with IIS).
But I don't know how to put the program online (internet)? Which file should I use?
Any settings? (the sample book didn't say anything.)
The Visual Studio 2003 seems did some setting on the local machine.
One more question is "How to do debug?"
I built a test client. But how can I know if the web service (server) followed the correct steps when the client asked a data process?
thanks a lot,
larry

Hi
I worked with ATL and i believe it has advantages over MFC when creating controls , COMponents..
Q1 :
what about WTL as an alternative for MFC for dialog based apps ?
the only advantage I know is it's available for download from MS site.. But no support..
Q2 :
Supposed I have a good knowledge of ATL..Is it easy to switch to WTL from MFC ?
|
|
|
|
|
|
thank you...
the small EXE compared to MFC statically linked EXE is a top feature..
but seems i'll have to re-write some classes provided in MFC.
it'll be a good practice anyway

WTL has several advantages. One of whch is that it is template based which allows you to change the base class of many of the GUI classes. WTL also does not have the DLL hell that mfc does. MFC is bloated, it contains functionality that STL and even C++ have better implementations but these are here to maintain backward compatibility. The Doc/View in mfc is very annoying/difficult to use in multithreaded applications as all windows must be created and accessed in the main thread. But WTL also has disadvantages. Not being supported or documented are big problems. Also look at code project. How many controls are MFC and then look how many are WTL?
