• Windows Forms Help: Multiple forms vs MDI Application in VS 2005 express

  I'm a bit confused. I'd like to use different windows forms to show different views of a database. Would I use an MDI application, or many (main) forms in a "normal" windows application I assume that having many windows, means that one has to be displayed from another or from menu. Therefore many forms must be able to be open at the same time. Will that work The other benefit to MDI is that all of the other forms will be "within" the MDI parent. This allows the end user to minimize all app forms just by minimizing the MDI parent. ...Show All

• Visual Basic file rename in VB .net

  Hello I try to rename a file by file.copy(oldPathName, newPathName) then file.delete(oldPathName) File.copy works. But somehow, a message saying oldPathName is being used by another process, when it tries to delete the old file. Any idea why this happened and how to make it works. Thanks Quin Why not use the My.Computer.FileSystem.RenameFile Method to do the job rather than creating your own combination of copy and delete. There are more issues involved in recreating your own two step process such as timing, and fallback if failure occurs. I've found its almost always better to use whats available rather than trying to recreate the wheel. My.Computer.Filesystem.RenameFile htt ...Show All

• Software Development for Windows Vista How to communicate from Workflow Webservice to Console Workflow host?

  Hi, Newbie question ... I am trying to write a solution that has a console application hosting the workflow runtime, and exposes a webservice, which, when called, creates a new instance of a long-running workflow, to be added to the runtime running in the console app. (the webservice is running on the same machine as the console app) I have created and exposed the webservice without a problem. However, I don't understand how to get access to the workflow runtime running on the console in order to create the new instance for the new long-running workflow. I'm SURE it's a dumb question with a REALLY simple answer, but any advice would be gratefully received. Cheers folks. Once you have expo ...Show All

• Visual C++ Try This Code In VS2005

  Here is a very problem i came through while writing a very simple program in VS2005 Professional Edition. Try the following code: #include<iostream> using std::cout; int main(); { int i=0; cout<<(i+1)<<" "<<i++; return 0; } The expected output is:1 0 However,the output comes out to be: 2 0. When i tried the same code on dev-cpp compiler the output is as expected i.e 1 0.

• Windows Forms FileIOPermission on My.Application.Info.DIrectoryPath

  Hi all, As the title suggests, I am getting a System.Security.Permissions.FileIOPermission exception on this line of code: ... Dim path As String = My.Application.Info.DirectoryPath ... I am calling this line within the Form_Load event of a Windows form. Do any of you have any idea as to why this is happening Thanks, Stephen. It sounds like your application is running in a security zone where the FileIOPermission is in some way restricted which doesn't quite work for DirectoryPath. What zone is your app running in Any chance of increasing it ...Show All

• Visual C++ Memory leak

  I have a method that continuously reads 1MB of data from a hardware in a short period of time. I used a memoryStream data structure for this. In every call of this method, a memoryStream is created and used to read the data, and then it is closed and goes out of scope. These are my assumptions in this implementation: - The garbage collector will free the memory used for the memoryStream when its instance goes out of scope - The allocation for the memoryStream is done from the Large Heap objects, because of their 1MB size Therefore, I expected to see an increase in the memory for a short time until a gc collection of the 2nd generation occurs finally and the memory decreases. However, the result is different: ...Show All

• SQL Server Creating full-text indexes on a table in a publication

  I have a table that is in a one way transactional publication. I need to create a full-text catalog on this table and have that catalog exist on the subscriber as well. I understand simply creating a FTC for an object in a publication will not cause that FTC to be replicated to the subscribers. I have scripted out the command and tried to use sp_addscriptexec to push it to the subscriber. When I do this, I get the following error: Last 183 characters in 'sqlcmd' output buffer: Changed database context to 'database'. Msg 574, Level 16, State 1, Server SQLSERVER, Line 2 CREATE FULLTEXT CATALOG statement cannot be used inside a user transaction.
