If the lib files were built with the later compilers you will have link problems building with VC6. The latest version of Platform SDK has some libs that will not compile with VC6.

Thanks a lot Christian. You are right,I meant to call.:-O Thanks, E.A.

Thanks Jon. But is that the only step required to expose the project through COM? Do you have any detailed link that can help me out with that? Thanks again, E.A.

Yup, ehat Christian said. Or you can use the search function of Codeproject ;): PictureBox with zooming and scrolling[^]. Pompiedompiedom... ;) "..Commit yourself to quality from day one..it's better to do nothing at all than to do something badly.." -- Mark McCormick

As far as I know, the picturebox does not directly support such a thing. You would have to write custom code to scale the image from an offscreen source image, then reset the picture box .Image property. You could also write your own simple custom control that intrinsically supports image scaling, which would be more elegant and probably smoother.

Do you mean scrolling a PictureBox? Read this ms-help://MS.NETFrameworkSDKv1.1/cpref/html/frlrfSystemWindowsFormsScrollBarClassTopic.htm Basically you attach a ScrollBar component to the picturebox. In the link there is a full sample. Eduardo Diaz site | english blog | spanish blog

Did you try setting the WindowState property of the form to Maximized[^]? Regards Senthil _____________________________ My Blog | My Articles | WinMacro

You scroll an image by changing which part of the image you draw. You change it's display size by drawing it to the size of the window you're drawing on. Christian Graus - Microsoft MVP - C++

Thanks a lot Andrew, Hope this might help me sort it out. Best Regards, E.A.

What if I have the following case : struct x (whose structure is unknown) x* a = function(string m); int b= function2(a,....); If I used your idea, will it work in that case? Thanks for your help,I really appreciate it... Best Regards, E.A.

Hello Using DrawImage method of Graphics class you can specify any size for your image. And it will be drawn using that size. With best regards, Andrew

Look at http://www.pinvoke.net/default.aspx/Enums.DFS_VOLUME_STATE[^] This an example may be help tou to convert your enum If you look at the left side from this page you will see many Enums you can look at them MCAD

Thanks Muhammad, I have read about P/Invoke... My problem now is with marshalling the data between the managed and unmanaged code... The unmanaged function that I want to call has the following input parameter of type CvContourRetrievalMode that takes only 4 values ,either CV_RETR_TREE ..etc I don't know if it would be correct to use an enum in this case? Thanks again, E.A.

Use the dll file. I don't know what the exports library file is for. Tech, life, family, faith: Give me a visit. I'm currently blogging about: Who is Jewish, the Trivia Game! Judah Himango

Hi there, Thanks alot for your help..But the problem now is that ,when I create buttons whose location are outside the form size, I can see them..what would be the solution to that??? I don't want to resize the windows form as its size can exceed my monitor size,but I would rather prefer a scroll bar.. Any Idea how can I solve that?? Best Regards, E.A.

It should be sufficient to assign true to the Form.AutoScroll property. If this property is set to true, scroll bars are displayed on the form if any controls are located outside the form's client region. Additionally, when autoscrolling is on, the client area of the form automatically scrolls to make the control with input focus visible. www.troschuetz.de

There are a number of articles with programming examples on this site (and others) relating to converting a bitmap to a region for irregularly shaped forms and controls. You can of course fill a region for any purpose :-) http://www.codeproject.com/csharp/bmprgnform.asp Sorry I'm using FireFox, no clickety..:omg: Gary
