• Windows Forms [c# .net 2] Exporting data from dataGridView

  Evening. I have an unbound dataGridView which I'm populating programatically (not using a dataset) from xml/user entered data. What i now need to do is when the user clicks save i want it to write all data from the dataGridView to an xml file. I think the only/best ( ) way to do this is to iterate through each row/cell and write the xml file manually. Problem is, I just cant seem to do the forloop right. Can someone help me out Thanks. Michael It's up to you to decide your xml schema. The only reason i used column name is that when you want to load the xml back lateron, it's easier to map the values back to the columns. Otherwise you have to use your own code to map your element name back to column name. A ...Show All

• Visual C# Multiple Projects

  I have two projects under one solution. Each of these projects opens the same bound database, Is there any way I can use a common routine to assign the bound database and which app.config should it be in. Share the code that accesses the database. You can either move it into one project, expose public methods for the other project to call, or you can create a third data-access project, and call this from all your other projects. ...Show All

• Windows Forms "View Designer" on form prompts for check out

  Visual Studio 2005, VSS 6 I have a form that I have checked into SourceSafe.  In my Visual Studio solution, when I right click and select "View Designer", the "Check out for edit" dialog appears to prompt me to check out the form from SourceSafe.  I have not changed anything and simply want to open the designer to view it.  If I go ahead and check out the form and close it, saving changes, then do a "Compare", all files are identical, including the .cs file, the .Designer.cs file and the .resx file. The form was not doing this before.  It has several controls on it.  I had recently made some changes to the form - adding a TableLayoutPanel to arrange the existing controls.  I also set some ...Show All

• SQL Server storing values using a custom assembly

  I have a need to save a value or set of values that can be recalled for a calculation for each cell in a MDX query. Specifically I am trying to calculate the linear regression line over multiple days where the granularity of time is 10 minute periods. Using the LinReg functions in MDX perform very slowly. This is because the linear regression line is recalculated everytime the function is called, something that isnt necessary in drawing a trend line - calculate the slope and intercept ONCE and then use the slope and intercept to calculate the next point on the linear regression line. So, I'm not sure how to accomplish this using a custom assembly. If you declare the functions as static in the assembly, then you cant recall any member varia ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. In Game Movies

  Does anyone know whether the XNA Framework will allow for games to be written that have Cut-Scene videos, perhaps using non-Microsoft codecs such as divx or another codec that allows high-video compression to limit the size of the game. Will the game be able to use any audio/video codecs that Windows has installed on it, and will it be able to load pre-written non-managed code DLL's Dr.9 wrote: +1 How do we formally request it XNA builds should at the very least be able to play high res windows media 9 content. - Nevermind, I found it on the 'features request'.

• .NET Development Windows Services and COM interop

  Here is what I am trying to do: I have a very simple test DLL that has one operation called 'Get_Stuff(String)' this simply returns a string with some hard coded text. This works fine if I create a windows app in VB and then call the operation on the DLL, so I know the code is right. However, if I create a Windows service (again in VB) and use the same code I get an error. I've set the service to run under my login rather than local system because the DLL needs to access network drives. The error I get is:  Error: 429, Cannot create ActiveX component. As I say, identical code works fine as a normal windows app so does anyone know what is going on here As I understand it the service will still be running in a dif ...Show All
