• Visual C++ How to define a class in C++ (MFC)?

  I have a dialog based MFC application and I need a dynamic array whos type is a certain class. I tried to enter a prototype in dialog's header file and class definition in dialog source file but it didn't work. Then I tried with Project->Add Class->Generic C++ Class and again with no success. I continually get some of these messages: Error C2501 and Error C2059 ..... It would be pretty neat if I could put both prototype and class definition in the dialog source file. Your header needs to include the header for the class you're putting in your collection. Then it should just be: #inc ...Show All

• Windows Forms Inheritance Base Form lock

  I am using a base form which has menu and toolbar in a windows forms application.  I changed modifier property all the toolbar items and menu items to protected. The other forms inherits the base form. I can see the controls on my inherited form but can't click on any button on toolbar or menu and neither I can write code for events for the controls on base form.

• Visual Studio ReportViewer data binding (NOT design time) in ASP.Net, please help

  I am trying to bind a report to a datatable (or dataset) in asp.net. The only way I can see is via an ObjectDataSource (unlike windows where I can bind direct to the datatable). Is this the case, is it not possible to bind direct to the table or dataset Assuming we have to go through an ObjectDataSource, I have succeeded in building a working example using design time binding of the report to the ObjectDataSource, and adding a handler to the ObjectCreating event to put my datatable into its object data source property (see snippet1). However if I try to create the ObjectDataSource programatically (see snippet2) then the report doesnt ...Show All

• Visual C# running an application from resources

  Hi i embbed a application as resource.. can i run that app from the resources.. or how can i now extract and put it some where that app and run it.. please post some sample code Then I believe that you could convert a stream of the embedded resource into a byte array and load it up into an assembly as I suggested. Also, you always have the option of taking the stream and storing it as a physical file and executing it directly. But I think the former choice is less ugly. ...Show All

• .NET Development consume coldfusion web service in asp.net

  Hi I need consume a coldfusion web service in asp.net. anyone has done this before a code sample will be a great help!  thanks in advance!  That's correct. The WSDL file describes everything about the web service, location, protocols supported, methods, types, etc. As long as the cold fusion web service exposes a WSDL file then your .NET client can add a web reference (alternatively you could use wsdl.exe tool) to this WSDL file, to build a proxy class, and then from your .NET application you can invoke the web service just like any other classes.

• Visual C++ Comparing files

  I wondered how antivirus programs use the virus definitions, and what is a "virus definition" because as you know a simple antivirus program is about 15MB but it supports thousands of viruses. How is that accomplished ___Michael___ wrote: Thank you. But can you tell me how they define which bytes are unique. And is it that possible to be done with other file types like *.mp3, *.avi etc. Viral signatures are obtained typically using reverse engineering techniques.
