• Windows Forms sendKeys raised SecurityException

  I'm looking for a way to send the enter key to a textbox when I click on another button. I found that sendKeys seems to be my solution. However, I set the focus to the target textbox and called sendKeys in my button click event handler. It will raise an securityexception. Please advise. Thanks! SendKeys partially simulates what you ask. Seeing the UnmanagedCode exception is something the enter-key wouldn't generate. To resolve the issue, you must grant the assembly or code the appropriate permission. If this is not possible in your environment, there are alternative approaches. Another alternative might be to derive a TextBox and ...Show All

• Visual Basic Need FileSystemWatcher Advice

  I am creating a “sweep” app for my FTP server (local, in my office, app to live on same computer) that will watch for new folders being uploaded and then move them to a pre-designated location. I am including in this app, a timed comparison check on the new folder size to make sure that the folder is fully uploaded before moving it. I assumed I would have the FileSystemWatcher on the same timed event, but apparently (I think) it is not behaving correctly because it is being turned on and off with the timer. I changed the FileSystemWatcher to load with the form, and be running constantly, and checked my CPU usage with the “W ...Show All

• Smart Device Development VS2005 Compiler Bug?

  I have some source code that does DES, 3DES encryption decryption based on the algorithm. A lot of bit operations.

• Smart Device Development Visual C++ Express and *.ocx

  I need to create a "signature" .ocx file. RSView will link to an ActiveX .ocx to run on a WinCE 4.10 box, but has to set up the linking on XP. I expect it doesn't need a "matching" COM server, just a stub with the right "signature" to read a table or variables passed. Embedded C++ will create the .ocx for use, but I've not gotten one built for linking. Can Visual C++ Express do this dave Visual C++ express edition is meant only for desktop development. You can not create an application for devices. Are you creating OCX for for desktop ...Show All

• Visual C++ dialogs

  hello, i just started programming using this software and i was wondering if anyone could help me. given i have 2 dialogs. how do i add the 2nd dialog class as a variable to the first dialog class thanks! First, you need to #include the header for the second class in the cpp file of the second dialog.  Then you can just create instances as you would any other variable.  That's assuming you only want to create a variable within a function.  If you want a member variable, you need to put the #include in the header file for the first dialog.     ...Show All

• .NET Development Install .Net 2.0 runtime on web hotel?

  Hello all! Sorry if I'm posting this in the wrong category, but I didn't find a more apropriate one. I work for a small ISV / Hosting company.  We have a web hotel with 50+ .Net 1.1 webs running on a Win2000 Datacenter box.  I want to install the .Net 2.0 runtime on the server, but I was wondering about possible side effects.  Will all webs automatically start using the 2.0 runtime   Is there anything in the .Net 2.0 runtime that will break our applications Thanks in advance! You can have both of runtimes installed on the same machine, it should be no problem. Your webs will not aut ...Show All

• Visual C++ c++ compilation strategy

  Well .. this is probably not specific to C++ language. It is a more general question on the requirements of including headers, etc, and so sort of basic, of compilers. I have been looking at translation units and linking, etc. I learnt that there can't be duplicate identifiers in all of the translation units combined. If there are duplicates, it's a linking error. It can be avoided by using extern keyword for all the duplicate declarations of the identifier. Each .cpp file that is included in the project is compiled separately and so results in a compilation unit. The compiler requires that before the code is compiled, the identifier must ha ...Show All
