• Windows Forms Modify ConnectionString

  Hi, I searched, but couldn't find an answer. Is it possible to modify a connection string at runtime This code throws an exception, not sure how to fix. string connectionString = this .txtConnectionString.Text; ConnectionStringSettingsCollection col = ConfigurationManager .ConnectionStrings; ConnectionStringSettings section = col[ "MyConnection" ]; section.ConnectionString = connectionString; The last line throws this: System.Configuration.ConfigurationErrorsException was unhandled Message="The configuration is read only." Is this something I can configure I have a requirement to allow certain users the ability to change the connections string, rather than forcing them to modify the app. ...Show All

• Smart Device Development write to file...CFile?

  Hi folks. Simple problem and I've searched a lot and just can't seem to get it to work: I need to write null delimited strings to a simple text file on a smart device. I've tried CFile and CStdioFile and can't get it to work (I think because I can't figure out a way to convert a CString to a const char *). I tried this but I get a bunch of weird boxes at the end of and before every line of text: CString thisString = "Hello there"; writeToFile = thisString + _T( "\r\n" ); csfWrite.SeekToEnd(); csfWrite.WriteString(writeToFile); I just read that apparently CStdioFile is not supported in smart device applications... Is that true Can someone please tell/show me a way to write to a text file Thanx in ...Show All

• SQL Server Newb question

  If I am using Ado.Net from a .Net Class library hosted outside SqlServer to do Sends and Receives do I have to use anything else other than queues The reason I am asking is because I already have an abstraction layer for a couple of our queueing systems and I was hoping to put SSB in there as well but the abstraction layers' primitive is the Queue not Conversation/Dialog/Service, etc. Thanks Costas Uncomment the begin dialog lines. Use the @service parameter as the to service in that statement. That will allow you to begin a dialog and send a message in your stored proc. This proc can be called from ADO.Net. ...Show All

• Visual Studio Express Editions Stream data revisited.

  Hello all, I would like to ask for some opinions on the best way to do something and possibly the solution. I am beginning to think that my "programming logic" is off when it comes to figuring out how to do something and I would like some advice on that as well. I will use my current project as a case for this. I need to stream data into an application, run calculations or manipulation queries against the data and output the data into a Data Grid View (eventually I will use C# to access Excel and create a custom report). My first idea was to stream the data into a list and from the list into a DataTable then to the Data Grid View. I was advised to stream it directly into the DataTable. Below I have pasted the code for the main form and th ...Show All

• SQL Server Document Map

  Problems with Document Map creating a side scroll to get to Up/Down Scroll for the Map itself. There are two scroll bars once you side scroll over in the map window. Anyone seen this or know how to fix Or Anyone know how to change any of the properties on the Document Map or map window Thanks!!!!! Hi, I wondered if you ever got a resolution on this. I have a similar problem that once I deploy the report the scroll bar for the document map does not let you scroll to the document map. It only allows you to scroll through what initially fits when the report is first displayed. Before it was deployed, when the report was previewed, the scrolling worked fine... it was only after it was deployed that I ...Show All

• Visual Studio Previewing a sample report at runtime?

  Hi there, I am writing a windows forms app (C#, VS.NET 2005) that includes a few reports. I want to be able to provide something similar to Microsoft Small Business Accounting which shows a 'sample' report as an image when the user clicks on different reports in a list. I considered exporting a copy of my report to HTML which I could then display in my app, but my report only has PDF, rtf, MS Word and Excel options for exporting. I also wondered if I could access the image preview generated when you check the 'save image preview' option for the crystal reports, but I cannot find any information on accessing this. Has anyone got any suggestions Many thanks in advance. James ...Show All
