• Visual C# StrongNameIdentityPermission

  I tried to protect my entire assembly by using StrongNameIdentityPermission at the assembly level using Request Minimum with the following code [assembly: StrongNameIdentityPermissionAttribute(SecurityAction.RequestMinimum,PublicKey = "002400....")] But this did not work even when both the assemblies had different strong names.Can anyone tell me where i have gone wrong.Thanks If the clients have full trust, the StrongNameIdentityPermission will not help.

• Visual Basic About Notify Icon with windows service

  Dear all, I am programming a windows service that will constantly run, and this application associated with a notify icon. I got a problem when I login and start this service menually, the notify icon displayed proerply. However, if the service is started automatically, the service will run in the background properly, however, if I login the windows this icon did not showed up in the system tray. I have tried search information on the Internet about the Notify Icon but no luck, I only got information that the tray will be destroyed once a user logoff, and recreated after logon.

• Visual Basic OTP: Redistribution of .OCX files

  We have an application in the field that is installed on a number of workstations at sixteen sites. The latest build now includes Flexigrid which was not in the original install set. Is there an easy (from a user perspective) way to include the OCX only as an update without re-installing the whole application Our users are Windows 2000 & XP based. Any thoughts OK - I gathered as much, from the fact that you're using an OCX, especially one for a grid. VB6 support has ended, and as such, VB6 questions are off topic here. You could try www.codeproject.com or www.vbcity.com ...Show All

• Visual Basic Printing an rtf file with printform

  Hi I love the idea of the printform, it was one of my favourites in the vb6 code. Although in vb6 it was possible to print a flexgrid (or even a textbox i think) which i used frequently. Is the same things possible with the printform, or would i have to make the controls the exact size of the window and then use the printform I would like to print an rft file and what would be the easy way of doing this Getting WYSIWYG results from a .Net Rich Text Box control. ...Show All

• SQL Server Data Flow Task empty after check in

  On my office PC I have a strange problem with Data Flow Tasks. When I check-in a package into Source Control (Team Foundation) I usually have some empty Data Flow Tasks in the packages...even if I haven't changed that Flow Task. This is really frustrating cause when running the package all goes well, but after a whil you notice that some tables are empty. Does anyone know what the problem is Pukmaster wrote: Well, first I thought it was just my system, but as we can see there are more having this problem. If everybody thinks this is a real issue and not some sort of configuring error than someone must open a issue (don't know the formal way to do this). But, thanks for all suggestion ...Show All

• SQL Server Seeking help demonstrating a simple drill down in Report Builder using Adventureworks

  Folks, I'm interested in demonstrating how ReportBuilder can let a user drill down through relationships, as it described here, where it suggests that a report of employees could have them click on department to see other employees in that department: http://msdn2.microsoft.com/en-us/library/aa337330.aspx Unfortunately, it only says that "the person who created the data souce" made the fields "interactive". It doesn't clarify how they are to do that. I realize there's an option to create a report and save it as a clickthrough from another, as described here: http://msdn2.microsoft.com/en-us/library/ms365324.aspx But I was hoping that instead something more straightforward may be possible in the report model design proce ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. SpriteBatch Vs Sprite : 0 - 1

  I have created my own TiledLayer class, converting my old code. I have noticed that the new SpriteBatch class is more slow than old Sprite class. Someone Knows why I use 16 x 16 tile in a 640x480 screen. With new class the render is very slow, while with the old one I have also to reduce the animations' speed. I would like to know this as well. I have created a tile based RPG and when I try and display a simple 50x50 grid of tiles, the game nearly brings my machine to a halt. I also noticed in the Spacewar demo when you shoot too much, the game will begin to lag horribly. This should not be happening, we should be able to get thousands of sprites on the screen before we even begin to notice anything ...Show All

• Visual Basic Compiler does not warn when assigning to readonly property (Restated, Microsoft responses so far inadequate)

  Dear Microsoft, I am afraid that the Microsoft respondents to my problem so far have missed the point! That is why I try it again in a new thread. My original problem statement was as follows: "compiler did not warn me even though, I was assigning a value to a public readonly property. Not only that, I have configured the project's compile settings to treat all warnings as errors. Option strict is on." Later, I provided following information in my replies in my first thread: I am using VB Express 2005. I am developing a solution with multiple dependent projects/modules/assemblies. The public readonly property is declared in one project, while I tried (erroneously) to assign a value to this property in a class contained i ...Show All

• Visual FoxPro Upsizing and VFP

  I currently have some software that was originally created in the dark ages of Fox, my task is to upsize (make it more marketable) and use Sql Server as the backend. The tables are all upsized roughly 580 of them (ugh!!). Out of that 580 most of them are look ups. Venturing back to the software, the original developer was either a hobbyist or someone who loved job security because there is little or no comments in spaghetti she wrote. Also she wrote her own procedure for handling data calls (this is good, at least at first glance for me since I think I can get it to connect to sql backend without to much work) except that I can't get it "DO" without errors on run, errors related to file locations that don't have files since they ...Show All

• SQL Server variables in data flow OLE DB

  I'm storing a sql command (could be an SP call or simple select) that I would like to pass into the "OLE DB Source" container in my data flow task. If I choose Data Access Mode: SQL Command from variable, I get an error saying there is a data source column with no name. I've fought SSIS pretty good up to this point. I realize you need to "initialize" variables & expressions in the control flow ahead of time if you want to access them in the data flow. But I was kind of hoping that all I would need to do in this case would be pass a SQL command into a variable and access that somehow in the data flow without jumping through any hoops. Is this possible This is a great forum btw, thanks, Phil ...Show All
