• Visual Basic GAC'd dll does not work for an application.

  Hi, I have 2 windows forms applications which uses all the required functionality from a dll which is GAC'd. They both use the dll in the same exact way just different classes in the dll. I am installing the apps using the setup and deployment project msi created by visual studio (2003). The problem I am facing is that while the first app runs fine using the GAC'd dll the second app refuses to run (both the apps have the exact same dependencies). The second app only runs when the common dll is copied into the application folder. The error that I am getting when I try to run the app without the common dll in the folder is: MyApp.exe - Common Language Runtime Debugging Services Application has generated an exception that cou ...Show All

• .NET Development Timeout exception after the first request

  Hello, I've got a problem that is pretty difficult for me to nail down. I'm developing a C# WinForms application using Visual Studio 2005.  I have a form in the application that is acting as a feedback form.  It has a few text fields, and clicking on a button will submit the information to a web page for storing in a database.  The button is a "Next" button, which shows a label where I display some information about the connection and submission process.  Once that finishes, the user can hit "Back", fill out more feedback, and hit "Next" again to submit it a second time.  Or, they could have just closed the form and pressed the Feedback button to make it show again.  Regardless, however the second reques ...Show All

• Windows Forms Setting default values in bound controls on a form

  How do you set default values for bound fields in windows forms There are times when specifying the default value in the underlying dataset is insufficient. The fields are bound to a binding source which has an AddingNew event where you can do something like: e.NewObject = <something>. The something however needs something of the same type or else you get an error message of "Objects added to a BindingSource's list must all be of the same type". I assume this is a DataRowView except I don't don't know how to create one in this context. One way is to use code like this: DataRowView rowView = dsNorthwind.Customer.DefaultView[0] but this implies the row is already in the underlying dataset except it isn't becaus ...Show All

• SQL Server Basics of T-Sql and XQuery

  Pl let me know 1)the different between those two. 2)when to use and 3)anyone is Microsoft specific 4) for and open xml can be used only in xquery 1) XQuery is for querying XML fragments and T-SQL is a language that augments SQL for querying relational data. 2) You should use SQL for querying relation data and XQuery for querying XML within your applcation. 3) T-SQL has constructs that are SQL Server specific (i.e declaring a variable, while loops). The SQL part of the language has various Microsoft specific stuff, but we do try to align to the standard. 4) FOR XML and OPENXML are not part of XQuery. These were SQL Server 2000 technologies (still in 2005) used for composing and shredding xml to ...Show All

• Visual Studio Tools for Office VSTO Excel alternating row

  Hi, How can I change my ListObject rows in alternating color I already populated data into my ListObject but, I couldn't find out a way to change that in alternating color. Thanks, Myo Thanks, This DataBoundFormat method helps me out. I found out some formats that make my listObject in alternating color. But, for some cases, like if I want to change the color of some rows which value is under the required amount, this won't work. I try to use with this way : "lstTSearchResult.ListRows[3].Range.Interior.Color = 5" in sheet's activate event. But, it only works for the exact row. I can not change that '3' to a variable. Can you also help me out with this issue Thanks, Myo ...Show All
