• Windows Forms negative value of custom control property: strange behavior in designer

  I have a custom control which contains a custom version of the ProgressBar. This control accepts double minimum and maximum values which define the range of the custom ProgressBar. If I set, for example, a min val of -10 the Progressbar is correctly drawn and the code runs without problem. Then, if I reload the designer, the min value is changed to 10 (positive) in the designer window, but in the code it is still -10. If then I build and run the project it behaves correctly. Then, if I modify something in the designer window forcing to reload the form code, min value is set to 10, according to the value in the designer window. Why does this happen Is it a parsing problem I can't understand your reply. Wha ...Show All

• Software Development for Windows Vista Vista Certification Test Cases V1.2 Test Case 18

  Hi, question concerning ProductVersion-Property of installer package: is it necessary that this number must correspond with ProductVersion-Property of the executables or is it allowed that there are differences (My problem is, that we had used same Version-number for File- and Product-Version property of the executables whereas major number is the year of release (e.g. 2007). While validating msi package ICE24 error occurs). Concretly: can I set ProductVersion of msi to 7.1.0.0 and File/ProductVersion of MyApp.exe to 2007.1.0.0 We've been working with this group Keystone that has been real helpful with answering questions and keeping us updated on the certification program.

• Visual Studio Express Editions The Form1_Load event will not occur

  This is very disconcerting. Any new project will not show the main window. I noticed that the Form1_Load event is not happening even though the Form1_Load () sub is clearly specified as the handling procedure for the load event in the events section of the properties window for the Form1 form. Does anyone knows what is going on. I even did a side by side comparison of an older program, stripping it from everything and leaving only one form, called Form1 and a new project containing also one form called Form1 and made sure everything was equal in both instances of the IDE but still…the new project appears to run correctly but exits without every loading Form1 while the old one works as expected. I also uninstalled the net framework 3 ...Show All

• .NET Development Help with MS Access SQL Query

  Hi, i'm using an MS Access Database file and i need to fetch a certain amount of rows but "TOP" statement isn't enough because i want to show 50 results per page in my application, can someone tell me how can i fetch records between 50-100 i tried to use "LIMIT" statement from mysql ("Select * From SampleTable LIMIT 50,50") but that doesn't work on ms access.

• Visual C# While Loop Optimization

  I have a while loop that tests the value of (A*B > SomeNumber). This while loop is repeated at the very least several million times so code efficency is very importatant. A and B do not change while the loop is running. My question is would it be more efficent to first get the product of A and B and then test that variable against SomeNumber, or does it not matter Any other tips for optimization would be helpful too, thanks in advance.

• Software Development for Windows Vista Consistent set of components

  Please consider this as a plea for help - not a complaint I just downloaded and installed the newly released .NET 3.0 RC (Release Candidate) as well as the Update for Windows Communication Foundation (KB912817) which has likely nothing to do with WWF, so I am mentioning it here for the completeness sake. In addition, I installed the Visual Studio Extensions for Windows Workflow Foundation RC4, after the RC5 failed to install. Finally, I installed the Hands On Labs from http://wf.netfx3.com/files/folders/documentation/entry4919.aspx Then, I tried to re-create the Lab1 and found that everything behaves as it should, I was able to compile the application with no errors.
