• Visual C++ VC7 app with VC8 dlls

  Hi, My company sells a product which was developed using VC++ version 7. We allow customers to develop compatible .dlls to extend the application's capability. Our customers want to know if they can use VC++ version 8 (Visual Studio 2005). I have read everything I can find on the MSDN site and done some testing, but still can't resolve how the customers can successfully do this. I have run the vcredist_x86.exe on the target computer (which began with a clean, fresh XP image) and made sure that the "customer" developed .dll includes an embedded manifest. The dependency walker seems happy. The C run-time libraries are present in the WinSxS directory. Yet when I run the application (which reads a text configuration file th ...Show All

• SQL Server SSIS dataflow problem

  It just occurs to me that it might not be a bad idea to post again the problems in SSIS that I found back in the beta cycle which do not seem to have been fixed, to increase the chance that someone will notice them. (During the beta cycle, I spent hours trying to get bugs posted into the beta bug system, but the beta web bug site had so many problems that I could never get it to work, unfortunately, so I fell back to just posting my bugs and hoping some developers would notice them. Kirk had a thread for bugs and RFEs at one point, where I posted some of the important ones.) Here is another fairly bad one: The dialog that pops up to show fields in the dataflow which have been orphaned, after some fields have been removed earlier in the da ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Controlling Aspect Ratio

  So I was playing around with my XNA Control (1) for windows forms last night and got some sprites rendering based on some UI input (ie. press the "Add Sprite" button, file dialog comes up, and you pick a texture to add). I've got the control in a split container in the right pane. When I stretch the window, the sprites stretch right along with the window. The ideal behavior would be that stretching the window would simply give you more screen real estate. I'm imagining the way to figure this out will also apply to dealing with 4:3 vs 16:9 aspect ratios (2). Just need a few pointers on how to properly handle this :-) Thanks!

• Visual Studio 2008 (Pre-release) More control over callback DispatchRuntime in Duplex contracts

  Hi, I have two services that communicate through the exchange of one-way messages. There's not really a "client" or a "server", because either one of the services can start a conversation with the other one, so I will use "serviceA" and "serviceB" from here on. I used the WCF duplex binding in order for the two services to communicate with each other. I have written a custom ServiceHostBase that does some extra stuff for the project I'm working on and I would like to use the same ServiceHost implementation on both sides (i.e. "serviceA" and "serviceB") because the extra stuff is beneficial to both services. What I would like to do now is start my custom ServiceHost on the "se ...Show All

• Windows Forms couple of basic questions...

  i have the following requirements and I need to know if CO can do this -- this is a full trust app if that matters; have the app start with windows (optionally based on user config) write data to a data folder (how do i determine where this data folder is and does it persist across versions -- this is the local cache im talking about for offline use) create multiple threads that can reach accross network paths (both unc and http) and download files into the data folder interact with TAPI providers on the machine have user-scoped configuration that persists across versions (this includes the option to start the app with windows + many others) have the user be able to drop-in their own plug-ins (assemblies) which the app ...Show All

• Visual Studio Express Editions Text replace with File IO of binary/text data

  Perhaps not the appropriate forum, but..... I have a need to replace text in a file with new text. The files may or may not be text files in the sense that there may not be "lines" and they may not contain printable characters. I tried the StreamReader and StreamWriter approach and the String.Replace method. It works well, except that not all the file contents gets preserved. Three bytes at the start of the file are omitted. These occur just before the CRLF characters. Can I read the file in a binary way and then use the equivalent to the String.Replace The input will no longer be a string I must say...I'm not pleased with being sent to newsgroups to ask these questions. The forum format for discourse has ...Show All

• Visual C# using array lists

  I need an array like variable type that will automatically resize based on how many numbers are in it. After consulting my c# book, it seemed like an arraylist would be my best bet. After creating my array list, and adding some numbers to it, I realized that I had no idea how to read numbers from it. I thought it would be like reading numbers from a normal array, but this gave an error saying that I was trying to convert an object into an integer. heres what I tried (sorry the code is pretty crazy) for (int counter = 0; counter < gcGalaxSetup.gInSystem.Count ; counter++) { Matrix kartMatrix = Matrix.Translation(gcGalaxSetup.gShip[gcGalaxSetup.gInSystem[counter]].Position); ... gInSystem is my arraylist (or rather it re ...Show All

• Visual Studio Express Editions programming in C

  I’m trying to write and run C code in Visual C++ 2005 Express Edition and am having some trouble. I’ve put a .c suffix on the file and have checked to make sure that Visual C++ knows that this is a C file and not a C++ file by looking at the advanced properties. However when I click Build Solution I always get this: “ Command line error D8045 : cannot compile C file '.\example2.c' with the /clr option ”. I’m trying to compile this simple program: #include <stdio.h> int main( void ) { printf( "hello world. \n" ); return 0; } Thanks, this got me most of the way there, however I got fatal error C1010.

• SQL Server DTS Classes Not Showing in Visual Studio

  I am trying to use VB.NET to run SSIS packages. However I don't have the various dts namespaces available. When I attempt to import them I only have Microsoft.SqlServer.Server in intellisense. I am running on XP sp2, VS 2005 (full install) and even went so far as to install sql 2005 sp1 full install on my local machine. What gives with only having Microsoft.SqlServer.Server available thanks, Scott But did you specifically install Integration Services You can have the development tools without having all of SSIS. However there's no reason I can think of that the Add Reference dialog in Visual Studio wouldn't show a long list of Microsoft.SqlServer... assemblies, unless they weren't there. Y ...Show All
