• Visual Studio Tools for Office ThisAddin_Startup triggering on OLE client startup

  Working with VSTO 2005 SE Beta + Office 2007. Created a test application Add-in project for Excel. When I open a Word 2007 document with an linked Excel workbook (Excel isn't running at this point), I get the following error message in the Excel application space. System.NullReferenceException: Object reference not set to an instance of an object. at XL2007_Test.ThisAddin_Startup(Object sender, EventArgs e) in D:\vsto\ThisAddin.cs:line 24 Apparently, Excel recognizes there is a workbook and is able to assign ActiveWorkbook to an object variable. But when the object variable is addressed, the error message occurs. try { if (this.Application.Workbooks.Count > 0) { Excel.Workbook wb = (Excel.Workbook)this.Application.ActiveWor ...Show All

• Visual C# Class accessibility?

  Ok, lets say I make a new project in VS05. I create a button named button1 on a form named form1. Now I create another file and another class (Right Click, Add, Item... C# class). Now I am in another class in another file, but if I do "form1.BackColor" it doesnt work. I cant access the button either. I can also make a variable public int test = 34; Cant access it outside the form1 class either. I tried a lot of things (yes, including putting "public" keywords everywhere) but it wont work. Any ideas Thanks === Edited by AlexTurp @ 12 Feb 2007 11:26 PM UTC=== Both classes are in the same namespace of course. Perhaps your form1 and your new class are in different namespaces. Try either putting them in the same namespace of in the new c ...Show All

• Visual Studio Team System Opening a database project is taking a very long time

  Hello everybody, I have a little problem. I created a database project that represents a Microsft SQl Server 2005 database schema. When importing the schema (the database size is 1.7 Gb) it took 6 hours. After creating the project , when i want to open the project it takes 2 hours. How is this possible Can anybody help me on this one Thanks a lot, Oana. Well, I don't know if the slow down is only because of adding the project to Source Control. I created a new project , import the database schema and then i tryed to open the newly created project. The time for opening the project was the same .. a few hours. What should i do next Oana. ...Show All

• Windows Forms Dock property bug?

  Hello All. I'm wondering if anyone else has run into this rather bizarre behavior. I've got this form that every time I open it in the editor it shows up with the asterisk in the caption, like the dirty bit is set and there are unsaved changes. When I close it, I'm prompted to save the changes. Every time. It doesn't matter if I open it in graphic design mode or code editor. Well, my WTF bug went crazy and I traced it to a Text Label control. If I set the Dock property on this control, the dirty bit presents every single time the form is opened. If I reset the property to "None", all is well. I can duplicate this behavior on any new form with a "Docked" Text Label control. The Anchor property has no effect o ...Show All

• Windows Forms question of DoubleClick on ListView in C#,need help!!!

  Hi, does anyone know to write the C# codes on how to create a double click event for ListView to delete/remove the item that i select from ListView control The following event methods and Timer should do it. It detects the second click (was made for DateTimePicker which doesn't implement the Click or DoubleClick events. It is not 100% conserning the time of detection, but you may figure that out yourself. It does detect the second click: /* The events */ void DTTime_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e) { if (dblclickTimer.Enabled) { txtSecondClick.Text = "You clicked twice within 1 second"; } } void DTTime_MouseUp(object sender, System.Windows.For ...Show All

• SQL Server Database name

  Is it indeed a requirement that database mirrors have the same name on a server The reason I ask is that I have several servers with the same database name, and I'd like to mirror all of them to a single (disaster) server and, by necessity, have each mirror to a distinct db name.

• Game Technologies: DirectX, XNA, XACT, etc. Cursor.Hide() not working?

  In my C# Managed DirectX application, I'm trying to hide the cursor. I have tried Cursor.Hide() from within the form constructor, and I have tried oveeriding WndProc and trapping WM_SETCURSOR. Neither approaches seem to work. What other methods could I use The code below shows 2 methods of starting the application; both fail to hide the cursor. class World : Form { /* code */ } #if DEBUG // Run in while loop mode (better for debugging). using (world = new World()) { while (!world.Exit) { world.Action(); } } #else // Run in invalidate/paint mode (more efficient). world = new World(); world.ShowDialog(); #endif I used the Cursor property and a clear bitmap.  I also used ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. "Casting" Image to Texture2D for proper use in spritebatch

  How can you make a Texture2D from an Image type Without saving it to a file and then loading it - that would be just too sad.. You can't just cast it like (Texture2D)SomeImage. It's really giving me a headache, especially since in assembly it wouldn't at all be necessary to change one type of image to an other - it would just work. You don't want to be using the System.Drawing namespace, unless you don't care about XBox compatibility. There is no System.Drawing on the XBox. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Xbox Live Arcade

  Do any of you reckon that it's possible to make a game using the XNA express framework, and then get it published (by MS or otherwise). I think, looking at the standard of games on Xbox Live Arcade, that I can make a much better game than anything there. " I think, looking at the standard of games on Xbox Live Arcade, that I can make a much better game than anything there." That's easy to say but not so easy to do. That said, yes, from what I understand, a possible path to the XBox Live Arcade is: Develop game using GSE, Get game recognized/accepted by Microsoft for XBox Live, Get XNA Professional version when it comes out, Re-Compile/fix up game for XBox Live, Deploy to XBox Live.

• Visual Studio 2008 (Pre-release) App.config initialization problem w/ Beta 2

  Hello! We have a problem getting the WCF system started. Basically the ConfigurationManager fails to initialize from the app.config. The problem starts as soon as the "system.serviceModel" element is included in the config. This happens before we even try to create the ServiceHost; accessing any of the application properties (that are provided through Configuration system), throws an exception. We have Beta 2 environment installed with WF 2.2 with Orcas support. Are we missing something general or does this imply that our runtime/SDK setup is somewhat broken   Example of the configuration file is below (the initialization starts to fail as soon as system.serviceModel is included; even when being completely empty, or ...Show All
