• Visual Studio Tools for Office Why VSTO doesnt work on WinXp and it does work on Win2k?

  This is on open question  So any ideas are welcome in order to get a VSTO solution working in WinXp that works on Win2k. 100% sure it has to do with the dlls, but which ones and can they be updated manually   The two main errors HRESULT x800A03EC or  COM object that has been separated from its underlying RCW cannot be used You have to be more specific in your question, don't hesitate to give more details on what you try to do.... Did you install all the prereqs What is the VSTO version you are referring to ...Show All

• SQL Server XML Service Broker messages

  Hi, I have written a C# console application that adds a message to a SB queue and a C# stored procedure that reads the message from the queue. I have had so many problems that I'm beginning to doubt the usefulness of this, but that is probably just my frustration speaking. I am stuck on putting an XML message into the queue and reading the XML in the stored procedure. The console app has a simple object called Message. This class has 2 fields, a guid and a string. I serialize the object into XML using XmlSerializer. This results in an XML string that looks like this: < xml version="1.0" encoding="utf-16" > <Messa ...Show All

• .NET Development Web service for easy moving to production

  i have a web service on my test box. Let us say the IP is http://10.25.24.25/WebService.asmx   Now I have an application that refers this web service. I have compiled it and it works fine. The problem is now if I want to move both of these to production(say http://100.25.25.25 ) I have to re-refer the web service in the applications that referred the web service from my testbox ie by refering to the new production URL http://100.25.25.25/WebService.asmx Is there a way I can just replace 10.25.24.25 with 100.25.25.25 at one or two places before copying it to production and get rid of re-refering the webservice again ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Scene data

  Hi, Does anyone have any tips on how to run through scene-data. I've noticed that the data has to be 'tree-like' because you have objects, groups of objects and groups within groups. For example, if I have the text - 'This' in my 3d scene, all the letter objects are in a group (with a common origin), and the 2 parts that make the 'i' are in a group that is within the group. I had a good idea of writing a function which runs through the data, and when it comes across a group of objects - it calls itself . This works well with tree-like data. However, I'm not sure if the processing that goes on when a dynamic function ...Show All

• Visual Studio Team System license question

  I'm not sure if this is the proper place to ask, but I can't find it on the Microsoft site... If we have a team of 8 developers, and we want to use the Foundation server instead of VSS for its extra features, and our developers all do a bit of architect/test/develop, will the cost be around $83,000 from the licenses (8 * 10k for Team System, and 3k for the server) Thanks.. Or if anyone could point me to a an email of a person who can answer this question, I'd appreciate it. Hi Eric, My company is interested in evaluating the scenario where we have team foundation server installed, and we are using the source/version control feature ...Show All

• Windows Forms Binding Navigator Problem

  Hi, I was wondering how you see the code for the previous, first and delete buttons on the binding navigator. The reason being is I run my application and the user presses the + button which displays a new record but if they then press the previous or first record button the program crashes with an unhandled exception. This is because there are fields in the new record that are required. I have put in a try catch for the Save button click event as I can see the code when I double click the Save button. I can then handle the exception gracefully by displaying the error message to the user via a status strip label if fields are required ...Show All

• Visual C# Passwords...

  In my program I have a default password for an SMTP server. The problem is when using a program like Reflector it is very easy to see what the password is. How can I make that secure You can hide the password by storing it encrypted in code. You can either use the dpapi or ACLs to securely store the encryption key either in the registry or file system. If your application is distributed to environments that you don't have complete control to hide the key, then at least you can store the encryption key in the application and hide the password from casual observation. You can further enhance the obfusca ...Show All

• Visual Basic WebBrowser Control DocumentText Failure

  I have a problem that the HTML I load into a WebBrowser control does not display sometimes. Here is the situation: I have a parent child relationship, and I use a webbrowser control on the form to display the child detail nicely formatted. I use a specific subroutine to format a string which I then assign to webbrowser. documenttext. The subroutine seems to work just fine, but if it is the first time I am doing the display, it does not actually display anything. The program is quite involved, but here is what basically happens: In form.load I call a procedure to setup the display. The setup first calls some refr ...Show All

• SQL Server sorting on an expression

  I wanted to create a column which was one field divided by another field, and then sort on it. I started with Fields!FG.Value)/Fields!ADU.Value but of course when ADU was 0 it caused an error. then I went to =iif( Fields!ADU.Value =0,0,(Fields!FG.Value)/Fields!ADU.value) but sadily it evaluates both the true and the false return values before figuring out which one it would need to return. So then I used this. =iif( Fields!ADU.Value =0,0,Fields!FG.Value/ iif(Fields!ADU.Value=0,1,Fields!ADU.value)) Which actually works and returns what I would expect it to. Then I go into the report properties and say that I wish ...Show All
