• Visual Basic Folderbrowserdialog ContextSwitchDeadlock

  I have had a problem resulting in ContextSwitchDeadlock and a consequent build up in memory use. The following is a snippet which results in the error when using a Folderbrowserdialog control. How can the ContextSwitchDeadlock be avoided Private Sub Button1_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click FolderBrowserDialog1.ShowDialog() Dim tstart As Double tstart = DateAndTime.Timer Do While DateAndTime.Timer < tstart + 70.0 TextBox1.Text = DateAndTime.Timer - tstart Refresh() Loop End Sub I may have missed the whole point of what you are talking about, but anyway, the following change ...Show All

• Visual C# Commandline arguments question

  I am starting a process after setting some command line arguments. Is there any way that I can see what actually executed on the command line along with all the arguments that were passed Is this information stored somewhere after the process is started The reason I'm asking is that I am using a companies command line FTP program and I keep getting told that I am using bad command line arguments. The arguments I'm passing are valid, but I want to check to make sure that is actually what is getting executed. Thanks in advance! I guess it doesnt like the catfood you give it, consider changing the brand ;-) .....guess at some level it also depends how the external app reacts. You are aware that ...Show All

• SQL Server XQuery modifying element names

  We recently made changes to our code that involve a XML data to be changed in the database. I would like to change this: <element>      <text>hello</text>      <text>good bye</text> </element> to: <element>      <number>hello</number>      <number>good bye</number> </element> Is this possible through XQuery   If not, is there any way to do this via SQL   Note: I cannot do a string replace as other valid nodes are called <text> .

• Visual Studio Express Editions DLL Help "VBExpress"

  hi Someone can help me with dll creation I want only know how to do this. Thanks Shady Well, I feel like I have egg on my face again. Playing with that code again, I see that I did not add provisions to handle if someone sets the public properties to an unusable value. (Such as if they set the value to 'nothing') The one 'nothing' 'catcher' I have in there is set up wrong. Anyway, I'll get back to the code again soon when I get a chance and debug it a little better. Meanwhile, it is a starting place to see how dlls are done. Try a real simple one first and start another post on how to reference it in a using program if need be. I am also a beginner in this area and the steps are not o ...Show All

• Visual C# Passing a class as a parameter - gets error message

  I'm trying to pass a pointer to a static class to another routine, we'll call it 'bind', such that it can access a member of the class by name; however, the compiler generates an error message that says "Error 4 'nBase.cBase' is a 'type' but is used like a 'variable' ". But I want to pass the class. I'm obviously missing something about how to cast it or how to otherwise make it acceptable to the compiler to be able to pass it. In particular, the Bind() routine I'm calling expects an instance of a Windows.form, and the 'Form1' name suffices here. But this is a static class I'm passing, but perhaps using the class name is the wrong thing to try to pass as a parameter. Any smart folks out there who can tell me how I can solve ...Show All

• Visual Studio Tools for Office Outlook 2007 Ribbon Observations/Questions

  i have developed a custom ribbon for a custom message class: "IPM.Contacts. MyCustomClass " i note that inside the GetCustomUI() method I can;t seem to trap whether the ID relates to a custom message class or note, as they both come out as "Microsoft.Outlook.Contact". So I am assigning my custom ribbon to both the standard outlook form and mythingie form at this point. Am I doing this bit right case "Microsoft.Outlook.Contact" : return Properties.

  I'm setting up a testing environment from scratch and most of the testing we do will be in the UI space. Consequently, I've chosen Mercury MFT (formerly QTP) for this but would also like to be able to use the Bug management in TFS without my testers having to go from application to application.

• SQL Server Use parameter in field list?

  Hi. Hi I have a problem with using parameter as a column in an sql. Is this possible Lets say I have a input value @field1 that I want to use as field in my sql.

Ex: DECLARE @sql VARCHAR(8000) @sql = 'SELECT ' & @field1 & ' AS somthing FROM table EXECUTE(@sql) Is there anyway to use a input parameter as a column name Reporting Services.
