Can anyone help me figure out how to get a security descriptor working with the CreateNamedPipe API function? At this moment I get Marshal error 1336 "The access control list (ACL) structure is invalid." with the CreateNamedPipe function. All of the other functions seem to be completing sucesfully and are returning proper handles.[code]

I have an app that allows the user to choose an image, at design time, either as a straight image, or from an image list.
All cool so far, except that this is not happening from the visual studio property browser, its happening from a property grid that is a part of a type editor.
My problem is, both the image picker (actually resource picker), and the imagelist type converter rely on some design-time services to get the job done. In the case of imagelist, its the IReferenceService and in the case of the resource picker its a service called _DTE.
In the first instance of an edit from the visual studio property browser, I could get a reference to these services but (1) how can I add them to the type descriptor context of my property grid?
It would be better, for future proofing, if I could just copy a reference to all of the services in the type descriptor context. (2) Where does the property browser get these services from in the first place?
ETA: I still don't know how to do it, but I now know it is possible.
(1) Sub-class control and add a property whose type is an array of buttons.
(2) Add it to a form.
(3) Select the new control on the design service and edit the new property in the property browser.
(4) The collection editor dialog pops-up
(5) Add a button
(6) Edit image and image list - the type editor and type converter, respectively, behave as they should.
ETA2: Ok, I'm getting warm. It looks like you do it through the Site property of the property grid. I can create a new site, and pass it the type descriptor context I have a reference to and then it should have all the service. I'll give it a go ...

I'm using fileopen() function to open the file, after doing all the works I'm using fileclose() to close the file. But when I access the file again it returns already the file is opened by another process.
Sample:
Dim intFile As Integer = FreeFile()
FileOpen(intFile, mstrFilename, OpenMode.Binary, OpenAccess.Read, OpenShare.LockWrite)
FileClose(intFile)
Loading another form increases the memory usage of the application and after closing is not combing back to normal? dispose function at formclosed event is not doing that
View 12 RepliesI have a form that displays a graph. From the appropriate toobar button click frmGraph.show is called and it works. But when I call it from the assigned F6 function key the graph hardly ever displays. Sometimes it does display properly, sometime it flickers a one time display of the graph then it's gone, but mostly the form just draws the background but no graph. In debugging this i discoverd that putting a message box just before the call to frmGraph.show the graph will display properly everytime after i click ok in the messagebox. Anyone know how to cure this or at least a workaround that doesn't involve displaying the messagebox? This is the code with the messagebox("here") just above the call.

Problem is I can only get this working with document.ready - so therefore not when the updatepanel is run.

I found the following example of how to print a root directory on the net
Code:
Sub Main()
Dim Current As String
Dim Root As String
Current = Directory.getCurrentDirectory()
Root = Directory.GetDirectoryRoot(Current)
Root = Directory.GetDirectoryRoot("")
Console.WriteLine("Current directory {0}", Current)
Console.WriteLine("Root directory {0}", Root)
End Sub
However it just causes the error "name directory not declared"

the problem lies with "SHDocVw.tagREADYSTATE.READYSTATE_COMPLETE" I an example of it on the net and it works in the sample app but not in mine. It won't compile because it says "Name ShDocvw is not declared" and i've searched through the example app and can't find it "declared" anywhere. I had a look at the designer generated code and found

what is a AxSHDocVw.AxWebBrowser? Now i've done some searching and found that apparently "SHDocVw.tagREADYSTATE.READYSTATE_COMPLETE" no longer works in 2005.

My Problem is, that I have some Buttons, Labels and TextBoxes I need to generate after the User told a number of Players. With the Code I'm using now only the last Player will have these Controls working, because they are moved - for example - from Player 1 to Player 3. how to create such a ControlArray The biggest Problem I have is, that these buttons have to have names like "1", "2", "3" and so on (or if it works somehow to read out the Index of a ControlArray the names will not be necessary).
This is the code I am using right now to generate the Controls, but as you see it won't work, because the properties will be changed when the For-Function restarts.What I need is a hint on how to get these Controls/Buttons into a Control-Array and then read out the Index-Number to use them in the Functions that are called.

I've reviewed the other posts regarding this subject. I'm using VB from Excel and the function keys are not working. I'm running Windows Vista Home Premium with Office Ultimate 2007 Looks like Excel is running VB 6.5So, this used to work for me...I've used the debugger quite a bit. When I try the solutions suggested Tools->Options->Keyboard (after checking check-box to show all settings) when I click on the box just below "Apply the following additional keyboard scheme" the only item in the list is default. There is no selection for VB 6 or anything else for that matter.

I am looping through all folders on the computer in a background worker. Starting with just the C: drive, the function works perfectly I've been tasked with adding recursiveness to this function to loop through all subfolders within each and every folder.
This is the working code without recursive. Startpath is set = "c:".
Private Sub BackgroundWorker1_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork
Dim fs As New FileSystemObject
Dim fsfolder As Folder
Dim subfolder As Folder

EDIT: I was doing some testing and threw in an if check to skip the C:$ folders. Working ok so far and noticed something really strange. It doesn't loop through all the folders in the C: drive. I think it will loop through only the first 2 folders. One is C:Boot so I skip that and the other is C:Dev-cpp. It won't loop through the Program Files, Program Files (x86), or Users.
