• .NET Development Add record with null value to typed dataset

  Hi, Using the typed dataset functionallity, I encountered the following problem. I created a new dataset, added a table "Keyword" to it with the designer and let Visual Studio generate the typed dataset. In this table is a column "ParentID" which has these properties: AllowDBNull : true DataType : System.Int32 When I tried to add a new record to this dataset I noticed that I have a method dataset.Keyword.AddKeywordRow (string Name, int ParentID) (Name is just another column in the table) How I'm I supposed to get a null value into the ParentID field of the new record Or isn't that possible Kind regards, Christian Mol ...Show All

• Visual C# Getting color code

  I want to read the color code of a specific pixel as integer (if possible) that is loaded on a PictureBox and is in *.gif format in Visual Studio .NET 2003 in C#. Is there a way to perform such a task Bitmap bmp = new Bitmap(pictureBox1.Image); Color color = bmp.GetPixel(xPos, yPos); I should warn that this is a very slow operation.  If you want faster bitmap reads, lookup LockBits.   ...Show All

• Smart Device Development Debugging Multiple COM dll's

  I have a large CE workspace that I migrated from CE 4.0 to CE 5.0 using the built in conversion tool in VS 2005.  When I try to debug the code (running on a PPC 2003 device) I can not hit a break point in any of the lower level dll's.  Visual Studio disables them and I get the following message: "The break point will not currently be hit.  No executable code is currently loaded at this position." Is there something I need to do in the solution to get debugging of the lower level dll's to work Srinivas, Thanks so much.  The fact that you needed to set the path to the PDB combined with the ...Show All

• Visual Studio Tools for Office VSTO and Microsoft Office

  I am having trouble getting VSTO to work. When I go into Visual Studio to create the project I get a cryptic error telling me to check for disabled items in Excel (I have none) and then it instructs me to reinstall VSTO. A classmate suggested that it is because the University edition of Office (Microsoft Office Professional Enterprise Edition 2003) is crippled. Can anyone confirm if this is so Thanks, Michael According to the Office Web site, that edition will work with VSTO (if it is an academic-license edition): http://www.microsoft.com/office/editions/howtobuy/compare.mspx What version of ...Show All

• Visual C# Creating a random number of linklabels inside a groupbox

• Software Development for Windows Vista RuleConditionDialog and intellisense

  Hello, in my custom designer I can insert/edit condition rules througth RuleConditionDialog. In order to see the dropped activities I set the TypeProvider with all referenced assemblies and the code compile unit of the current workflow (code beside). Unfortunately I don't see the current workflow components (typing "this.myWorkflow1.") even if the code compile unit contains all activities (fields) declarations. How can I solve the problem Thanks, Pierre Pierre , There was a similar issue with code separated workflows (XOML) and the workaround was to some how cause an application idle event to fire, which ca ...Show All

• Visual C++ How to compile C++ function to be used by C# ?

  I want to write a native C++ function that I can later access from C#. Please keep in mind I do not have much experience developing on windows, (mostly unix) and that my only windows compiler is VS2005. I tried creating a MFC DLL. I am able to access this from a C++ .net program, but not from a C# program using P/Invoke. It seems that a plain MFC DLL is not "good enough" for use with DllImport. Is this correct It seems that I have two options: 1) compile the C++ function as a COM DLL (not sure how to do this from VS2005 - I don't see an option for that). I see an option for an ActiveX DLL...I hope I don't need to do th ...Show All

• Windows Forms Making child controls of UserControl editable

  I have a UserControl subclass, CompanyInfo, with various controls (Labels and Textboxes) on it. When I'm designing this class, I can edit the controls, move them around etc., which is fine. However, when I build CompanyInfo into a DLL, then add it to the Toolbox and drop it onto a form in the Designer, I can no longer edit and move the various controls that CompanyInfo encapsulates. I have tried setting these controls to public access, but that hasn't helped. I'm using C# in VS .NET 2003. Is there any way to get these child controls to be editable when my subclass is placed on a form If you have ANY solution to this problem, I'd be ha ...Show All

• Software Development for Windows Vista Delay Activity and ASP.NET

  I have a workflow that contains two HandleExternalEvent activities and a Delay activity all within a Listen activity. Obviously, when the Listen activity is hit, the workflow instance goes into an idle state. My intent is that if either event is not raised to the workflow within the specified timespan on the delay, an alternate path should be taken. The workflow never comes out of idle after the elapsed delay has passed. When I fire an event to the same workflow, the workflow instance is deserialized from the persistence store and starts up at the appropriate HandleExternalEvent activity without any problem. The workflow instance is hoste ...Show All

• SQL Server SRS 2005 and SQL Server 2000

  Can I create a report using the VS 2005 that is installed with SQL Server 2005 that I can publish to SRS 2000 Failing that, can I convert my SRS 2000 to SRS 2005 and create reports with SRS 2005 that use SQL Server 2000 data sources You cannot publish 2005 reports to a 2000 server. You can create reports for SRS 2005 that use SQL Server 2000 as a data source though. You should be able to upgrade either at install time of SRS 2005 or via the Configuration Tool after you have installed (there is an option to convert an existing SRS 2000 catalog to a 2005 catalog). ...Show All
