• Windows Forms How can I line up labels with textboxes in a FlowLayoutPanel?

  You know how in the VS2005 you have those grid snap lines, which let you align labels with textboxes in the middle (the pink line) Well flow panel still dumps everything aligned at the topmost corner for each component, and all the labels looks wierd. I could adjust the top padding on each control, but it's a pain, is there an easier way This question is better suited for the Windows Forms forum. Please reserve the C# forum for questions specifically related to C# itself. I'm moving this post to the Windows Forms forum. Michael Taylor - 6/9/06 ...Show All

• Windows Forms Scroll problem .HorizontalScroll.Value = 0;

  Hey Guys, I am linking to scroll bars together by monitoring if one changes and then simply making the value of the other one the same as the one that changed. Why does this line not work Blah.HorizontalScroll.Value = 0; Setting it to 1, works but setting the value to 0 does nothing! NOTHING! Kris Problem 1/2 solved.... i was using this: private void dgvQueryResult_Scroll( object sender, ScrollEventArgs e) { this .flpFilters.HorizontalScroll.Value = this .dgvQueryResult.HorizontalScrollingOffset } Where the HorizontalScrollOffest is different to the current horizontal value. So i have created a ch ...Show All

• SQL Server Using Sql Express databases with Windows Forms applications

  Hello all, I would like my newly converted to .NET 2.0 Windows Forms application to use an Sql Express database instead of MSDE. Previously, development was done on the default SQL Server instance using the full SQL Server 7.0. When deployed, MSDE was used with a named instance. The connection string in the application settings needed to be modified as part of the deployment. Now I've converted to .NET 2.0 and to Sql Server 2005, and/or Sql Express. What I'd really like to do now is have a project within my solution that, when built, creates the database by running scripts, and deploys that database to the output directory of the exec ...Show All

• Windows Forms passing variables to form

  I made my textboxes on form1 public. I was able to access them through my form2, after I made a statement like form1 form2 = new form1();   Problem is, the text boxes are all empty on form2. Is this because I initiated a new form1 and therefore the textboxes are set back to their default as empty How can I access variables stored in form1 from form2 thanks. To have one form talk to another, pass the Form as an argument   In class Form2, write a method like   Public Method(Form myForm1) {             myForm1.TextB ...Show All

• .NET Development 407 Proxy Authentication Required

  Hi All, We currently have an old Win32 (unmanaged) app out there written in VB 6.0 . This is a shareware app that has been around for a couple of years and has been downloaded by a number of users all over the world. This application talks to a managed DLL (a proxy of sorts), which communicates with a Web service . In other words, the managed DLL is really a proxy for the VB client to communicate with the Web service. The Web service is running on our central server and requires SSL in order to communicate. The VB client talks to the .NET proxy, which in turn sends all the information to our server. Any response received from the s ...Show All

• SQL Server Bitwise operation in SELECT killing performance, *sometimes*?

  Hi there, We have a high volume SQL Server which gets into trouble at times, with one query blocking out others for 10-15 minutes. The query looks something like this: SELECT * FROM MyTable WHERE MyQueryColumn & 128 = 128 ORDER BY MySortColumn There is an index that exists containing MyQueryColumn.  MyTable has somewhere around 550,000 rows, around 50 of which might match this query at any particular time. Almost every time this query executes in under 1 second, and everybody is happy.  However, once every few weeks (or months, even), this thing takes a dogs age, blocking loads of other queries trying to hit MyTable. We did a s ...Show All

  Hello! A small hint please! What should I do in order to have a background thread to be able to set the text of a textbox Earlier the Invoke() method was the solution, but what now Best regards, Henrik Dahl You should be able to use textBox.getDispatcher().Invoke to cause code to execute on the UI thread. Is there some reason that is not adequate There are certainly issues with this solution, but that is what the WPF framework requires. ...Show All
