• Visual Studio Help Needed to Properly Organize Projects, Etc.

  Hello... We need help/guidance/suggestions on the best way to organize our applications into VSS projects, and then how to use the setup going forward. We have a suite of applications that we sell as one product. So, the product we sell is, for example, named Foo, and Foo is made up of a number of different individual applications, for example, FooBar1, FooBar2, ... Ok. And, there are quite a few applications (.exes, .dlls, .ocxs, etc.) that make up Foo. Additionally, all the individual pieces (FooBar1, FooBar2, etc.) are written in different languages. We have Access .mde applications, we have C++ applications, we have VB 6.0 applications, we have .NET 1.1 applications, and we will soon have .NET 2.0 applications. All these diffe ...Show All

• Architecture Solution Design?

  I was wondering if anybody could give me a few pointers on designing a large solution. We have a rather large application written in a legacy codebase that we are rewritting from the ground-up in C# 2.0. One of the problems I constantly face is the fact that I would like to break things up into separate projects to group common things together but then I always face the problem of "circular references". Can some of you folks who are developing large applications give me some insignt in how you structure your solution(s) I have thought about having separate solutions, but that seems to defeat the purpose of having multiple projects in the same solution! Here's one example of a problem that I face. I want to segregate al ...Show All

• Visual C++ (MFC) What's the best way to play a wave file in MFC?

  I would like to play a wav file in a MFC dialog, just wondering what's the best (and easiest) way to do this Should I: - Use ShellExecute to play it, or - Import the wav file into the application as a resource, and play it out I'm not sure if the 2nd method is better, since I don't know how to do this exactly.

• Windows Forms Datagriview generated columns uncomplete...

  This is my scenary.... I have a model abstract class A...and i inherit it from an external assembly(let's name it B). I have in the first assembly a ACollection as List(Of T) which holds A collections.   When i try to bind a ACollection to a datagridview it doesn't create columns linked to B declared properties, but only those ines got from base class.   It's funny that calling .Getproperty method on class type doesn't let me obtain these properties, but using getproperties and iterating, this collection contains desired members...   What's happening What am i doing wrong (Moderator: Thread moved to this forum for better responses) ...Show All

• .NET Development Using C# to copy data from one database backend to another

  I am new to C# and I am trying to write an application that will copy data from one database and create a new table and insert the data into this new table. The SQL statement I want to use is something like "Create Table Blah as Select * from OtherTable" or Select * into Blah from OtherTable" I am dealing with 2 different database programs. I want to retrieve the results of a query another database program (Teradata) and copy it directly into SQL Server and create the table on the fly. I am assuming that using a SqlDataAdapter would be the best way. The data that I will be pulling from Teradata is a static so I could use a SqlDataReader if that would work better. Does anyone have any suggestions Thanks. ...Show All

• Windows Forms Changing the HEIGHT of a DateTimePicker

  hey everyone How do I change the height of a DateTimePicker control. It seems to be locked onto 20. Perhaps I can overide something If so, what thanks How do you resize the width Here's an issue I came across in different OS.

• .NET Development Is there by any chance an unmanaged version of Light Weight Code Generation API?

  This would be exceedingly useful since the byte code generation I am doing I would like to continue to do in an unmanaged envrionment with the framework I already have in place. Thanks for any assistance anyone can provide. Thanks again for your reply. What I meant by " Is there any call available on any of these Reflection.Emit objects that will generate the IL for a sequence of instructions in one call invocation " is that ILGenerator.Emit takes as its argument one opcode structure (eg Opcodes.Ldstr) and any parameters needed for correctly generating the byte codes for that one instruction. If I have 150 IL instructions, then I have 150 calls to make to IlGenerator.Emit. Moreover, I have ...Show All
