• Visual C# How to change the height of MainMenu?

  I need a graphical mainmenu and am able to do it with OnDrawItem(). However, I also need the mainmenu to be higher so that the sub-menu will show at a lower position and not block my graphical mainmenu. Any experts can teach me how Another way is to do it with PictureBox + Context Menu. The problem is I fail to hide a Context Menu when mouse leaves the PictureBox because when the Context Menu is shown, I simply cannot detect the mouse coordination.  I've checked this page already: http://www.windowsforms.net/FAQs/default.aspx PageID=3&CategoryID=3&SubcategoryID=71&tabindex=3   Good to know tha you have done it.

• SQL Server Multiple selects on PArameter drop down

  I have a parameter dropdown as USERID. I want a functionality that the user can selct multiple userid's to show more than one record as output for comparison purpose. How can i achieve this multiple select (i.e cntrl+click) within parameter dropdown. Thanks, Kiran. In the report parameters window, check the 'Multi-value' box on your UserID parameter. In the available values section, you can type the possible values, or query the database to get the list. You will also need to take the multiple values into account on your data query, you'll need to use 'IN' instead of '=' on your where clause for UserID. This will show on the report as a drop down, where the user can check which values to ...Show All

• Visual C# error message: An object reference is required for the nonstatic field ....

  I am getting the error 'An object reference is required for the nonstatic field, method, or property ' when I attempt to run my client application. I am not sure what is wrong and the documentation on this error (#CS0120) in the VS.NET IDE is confusing to me. Does anyone know what I am doing wrong MY code is below. People is a collection class and myPeople is obviously an instance of it. Because the error appears to involve the client code and not the class library with the implementation of People, I did not include that code. I could if it would be helpful.

• SQL Server Reporting Services 2005 - export to CSV with no header

  I have a very simple table report. I need to be able to export it as a CSV, but I can not have the first line being the header. I need just the data and no header. Is there a way to do this I tried working with the Output tab on the tables properties, but I only seem to be able to include or exclude columns not the column headers. I look forward to you response. FredZilz Hello, To do this you need to set the DeviceInfo parameter "NoHeader" to True: http://msdn2.microsoft.com/en-us/library/ms155365.aspx -Chris ...Show All

• Visual Studio Team System BEST PRACTICES: Importing Common Libraries

  OK, This is something that has bugged me for a while. I'm hoping someone with a little insight might be able to solve this one for me. Let's say I have two solutions. One is a "common base framework" of often-used classes and utilities. The other is a current project I'm working on that uses this framework. Now here's the stickler. The common framework is on one TFS server, and the current project is on another server altogether. I want the current project to use the latest bits, but I don't want to copy the source and include it into my current project. Then I'll have two codebases to maintain. I wish there was some sort of "Partial Solutions" that TFS could incorporate that would allow me to pick and ch ...Show All

• Software Development for Windows Vista sdk sample - boot image problems

  Using the sdk sample app: "C:\Program Files\Microsoft SDKs\Windows\v1.0\samples\winbase\storage\optical\imapi2sample" I tried taking the image from a boot cd (known to work). Then extracting the boot image. Then burning the data from the disc (temporarily copied to the hard drive) along with the boot image to create a new boot cdr.

• Windows Forms Problem occured while applying the launch condition check

  I was able to add the launch condition but there's a small issue. I do not know if I am wrong or is it a .net issue or Mind Manager issue. I check for FILEEXISTS in the launch condition with Mindmanager.exe as file. The Min version value is set to 6.1.809.0. I have this version installed and this did not work. A kind of hack, I just changed the Min version value to 6.1.808.0 and it works. My problem is solved (unless there's a MindManager version 6.1.808.0). But thinking deeper,should not the min version should be checked I agree that this is not really intuitive. To detect the version match Windows Installer uses the same algorithm as for file overwriting. This means: if the existing version of the file is identical to the versi ...Show All
