Hi all,

I am currently trying to find a charting package for our VC++ application. We have a requirement to display data in line, area, scatter, and possibly 2d contour maps. We are displaying large amounts of data which means refreshing quarter of million points in a scatter plot becomes very time consuming.

I would be grateful if anyone could recommend any charting packages which may help.

Many thanks in advance...

Would an embedded Excel chart suffice?

You might want to look at GigaSoft.
It's reasonably expensive, but I've used it a lot and seems to work well.

Apply different themes to single application

Hi,

I have to work on Windows Themes. I should be able to apply different themes to my application. These new themes must be applicaple only to my application and not to the entire Windows. On browsing the Google and other websites I learnt that UXTHEME.DLL has to be used to change the windows themes.

But I have no idea as to how to use this Dll to change the theme of only my application. I need to give an option in my application, say in the form of menu option showing the available themes, and allow the user to select one among them and then apply the theme to my application. My application should work similar to YahooMessager where we can select available skins/themes and it gets applied only to that messenger application.

I have never worked in this area. It would be of great help to me if any one can give me some inputs in this area.

Thanks
Madhavi.

Hi !

You should consider keeping a data value in registry that tells which 'theme' the user has selected. Then in the application, load this value and paint your windows and controls accordingly. It's called 'skinning an application' and is a very popular theme around the Net.

The UXTHEME.DLL is a library related to Windows Themes (how Windows windows, buttons etc look like). You should never change this DLL, although you can load it to make your application have the 'Windows XP' look and feel.

An alternative is to look for fore-skinned control packages, such as Dundas Ultimate Toolbox or Codejock's Xtreme Toolkit. These both contain hundreds of components in building custom-looking UIs. Both of these toolkits currently focus on providing Office 2003 look and feel.

One option is to just use Paint and draw your UI. Then use window region clipping and painting to push this 'drawing' as your main window. This is how the popular media player Winamp is constructed, for example. All the sections of the window are loaded from a bitmap or graphics file that can be custom generated. Creating a new UI is as easy as drawing a new graphic and making it follow an already working graphic file's layout.

Non blocking MFC Dll

Hello:

I have developed an MFC exe using a library that uses MFC objects. It pretends to be a driver for Bluetooth. This application uses a modal CDialog as main object. I am trying to convert this app to dll, in order to let the applications accesss bluetooth. I have designed an interface with two exported functions, Read and Write. I have done the dll but when it is initiated by the client it gets blocked as it uses a modal CDialog. I have tried to convert it to modeless but I don´t see the way as it has no parent window. Any idea of how can I solve the problem?

Thanks in advance,

Mikel Fernandez

Pass the desktop window as the parent. GetDesktopWindow() should help.

GetDesktopWindow() returns NULL. Do you know any reason?

Are you trying to use the DLL before there is a desktop. From a driver or a service for instance!?

problem with Picturebox / windows.h

Hi
I made an application that operates on the serialport. Using "CreateFile" I must include windows.h

Now I have re-written my app and wanted to include an image in the GUI, so I used "Picturebox".

However, with the picturebox and the picture, it looks like I cannot include the headerfile windows.h.
When I include it , I get the message:
error C2039: "GetObjectA" is not a member of "System::Resources::ResourceManager"

This errormessage is pointing to the line in my code dealing with the image.

Does anybody know what I have done wrong?

regards

Read this...http://www.kbalertz.com/kb_888267.aspx
said ifdef then undef on the getobject.... it is an
issue with including windows.h

If it works, let me know. I get a runtime error

ok - here is a workaround....

////REMOVE the code the IDE gave you!!!!
//this->pictureBox1->Image = (__try_cast<system::drawing::image *="">(resources->GetObject(S"pictureBox1.Image")));

///ADD This line
this->pictureBox1->Image = Image::FromFile(S"sm_titan.bmp");

This can get all crazy with a file name so here is an example with
a image directory and numbered images:
pictureBox1->Image = Image::FromFile( string::concat( directory::GetCurrentDirectory(), s"\\image\\image", imageNum.ToString(),s".bmp"));

Hope it helps!

That works no problem.

Hello,

Does anyone know where to get sample codes for LDAP client that works in Win9x and NT (XP, 2000 inclusive).

I am aware of Mozilla LDAP C SDK. Anyone uses it? Too bad it only works in NT based windows.

any suggestions are welcome.

thanks.

I have used implib32.exe to convert an ocx to Lib file.The lib file gets generated but when I am trying to link it ,it gives a linking error for the lib functions.
Plz suggest a way to do the conversion.

Re: vc++

Anthony_Yio2-Feb-05 23:03

I do not think you can use implib32 to just convert an activeX ocx to be functioning as a native dll.

From this URL.

It said what implib32 does is

DUMPBIN to create a file
which lists all exports of a DLL, reformat this file to .DEF-file using a
text editor and then use LIB to create a import library from the .DEF-file.

The ocx need to be registered with regsvr32 which basically register itself to the registry in order to be functioning and native DLL does not require that.

(or if you are doing some sort of hacking here, then that is another case)

I have installed Visual C++.NET and Visual SourceSafe 6.0 Netsetup, but Visual SourceSafe is still not available in the Visual C++ Add-In menu. Why?

I have downloaded the latest service pack (SP6) for SourceSafe, but nothing happened.

With VC++ 6.0 everything works well.

Pleeeeease help!
