• Smart Device Development Resource DLL still active

  Hi all, We made a .Net DLL that is the managed end of an unmanaged - managed bridge. There is nothing in the DLL besides the wrappers to the unmanaged function calls and the P/Invokes. When I terminate the program the managed DLL stays active. Any ideas on why it would stay in memory Do you have to terminate a managed DLL in some way Alex, Nope. Everything is a command-response call, no threads. I did notice that it's only when I am debugging and the debugger terminates in an abnormal fashion, like an uncaught exception. It does not seem to occur when I run the program outside of the debugger or the debugger terminates the app normally. ...Show All

  Hello I have just started to program and I am making a web browser for my school. I have the UI done it looks great for a novice I suppose!

• SQL Server how to save filename as columnname in Flat File Dest config

  I have created a SSIS pkg (datasource and flat file destination) I need to have the flatfile renamed after each exec to a column name that exists in the table I am running the pkg against. Where does the code get put to make this change after the file has been created Basically if I could run T-SQL after the file creation, I could make it work. thx.. Use an Execute SQL task to retrieve whatever you need (the full file name) into a variable, using a ResultSet of 'Single row' in the General node and mapping the output of the task to a variable in the 'Result Set' node. Then, rename the file using a File System Task to the variable retrieved in the Execute SQL Task. Do so by setting the IsDestinationPathVariable property ...Show All

• SQL Server Jump to URL: to open Word doc??

  I'd like to use the Jump to URL feature from within a report to jump to a Word doc. This seems to only be possible if the Word doc name is a single word i.e. "foobar.doc". If there are spaces the URL substitutes '+' between words. Is there some easy workaround Adding the Word docs to the project and attempting to open them as 'Link to Report' is not supported. The ability to store and browser-open Word docs as of a doc repository is a great feature of SSRS. ...Show All

  Hello, I'm using WPF to develop a wizard to guide users through a setup process. I'm trying to follow the vista guidelines. I came across a few postings on 'WINFX WIZARD FRAMEWORK'.

• Windows Forms DataGridView with a RichTextBox Column

  Can anyone point me in the right direction for declaring a RichTextBox column within a DataGridView... I know there are a few examples revolving around the Calander control... but... these examples all revolve around editable controls... the displayed control remains a TextBox until it is clicked... which is no good for me... as I want to display each cell as a RichTextBox. I assume my only option is to derive from DataGridViewCell and override Paint... but my c# is little weak and I'm struggling. In addition, I may be using a hammer to crack a nut... as all I want to do is to display text in a column which may have some words underlined... from my limited understanding of .net controls... I can only do partial underline with a R ...Show All
