I've got a basic email application set up, and I'd like the "To" field (TextBox1) to be an autocomplete textbox.I'd also like the user to be able to edit what their contacts are, and so be able to add named to the autocomplete suggestions.I can get TextBox1's autocomplete suggestion to come from TextBox2's current Text - however this means I can only have one name as a suggested contact.Ideally, something like a list box would be ideal, so the user can add and remove names, and this list would then provide the source for the autocomplete.

I have a ClickOnce application deployed to many workstations in my office. On it's first run it adds a registry key to the HKCU run group that adds itself with a "-minimize" argument. On each login the program starts and seeing the command line argument minimizes itself. However when a update is published the program does not update. If the program is run from its menu shortcut without arguments it runs fine. I then looked up how to update programmaticaly and put that code into my program to run at startup.
But my.application.isnetworkdeployed returns False when command line arguments are passed to the app and TRUE when run without command line arguments even though in both cases it is network deployed. Since my program starts up with command line arguments and stays minimized while the computer is on there is no reason for a user to close the program and reopen it through a menu item but as of right now that's the only way the program updates. Is this a bug or how ClickOnce is supposed to work?
Example: Create a new program. On the form add a textbox. In the Form load event put something like:
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
TextBox1.Text = My.Application.Info.DirectoryPath.ToString & "" & My.Application.Info.AssemblyName & ".exe"
MsgBox("Is my app network deployed?: " & My.Application.IsNetworkDeployed)
End Sub
Deploy the app. Start it with a menu item and it returns True. Start it with any command like argument (use the path from the box) and it returns false. Why? How is that possible? The app didn't magically become non network deployed because it was passed a command line argument.
any1 has any ideas on how to code a patch maker, (binary differential update) so when i run my patch maker, it output a program (*.exe) that will update files on another machine or local machine, assuming that old files to be updated to a new file having the same data in result;
and also the output patcher should be smaller in size (compressed)currently wad i could think of is a very very simple one but totally useless and not efficient and result large file size patch
1. where mine is read both file data
2. is both byte the same ?
3. [if not same ----> write down the marker value in outputfile1 and byte value in outputfile2]
3. [if same ----> do nothing]
4. read byte if available
5. (marker + 1)
the marker value is how many byte have been advanced so with resulting patcher will read those marker values to advance to the file address (which is the position number) and update accordingly to its byte value outputfile1 is marker values, outputfile2 is byte values corresponding to outputfile1 marker value to advance to the byte position

View 2 RepliesBackground: I am creating PDF with PrinceXML.I want to adjust the tracking on a paragraph in the PDF. So I select a unique piece of text, match it in the starting document, add a tracking attribute to the text, and re-create the PDF using PrinceXML.I have to delete the current PDF in order to create the revised PDF.When I was using the AxAcroPDF1 control in VB.NET all I needed to do was
1) If File.Exists(sPDFoutputName) Then File.Delete(sPDFoutputName)
Now I am trying to do the same thing but instead of using the AxAcroPDF control I am trying to do it with WebBrowser [Why am I doing this? Adobe places a burden on the developer to maintain a list of who has the program (Reader) to comply with US export law. This is an unacceptable requirement for the program.]
2)WebBrowser1.Navigate(sPDFoutputName + "#" + sPDFargument)
I want to jump to the same page that I was on so set the page to open in the sPDFarguement variable.Now when my program tries to delete as in #1 above I get error message that file is locked/in use.Question: How do I unload/close/unlock file in the webbrowser so I can delete it?The closest idea that I have found that almost works is to copy the xxxPDF to another file: displayPDF and only display the latter.With this I can delete and recreate a new xxxPDF. The problem again hits me when I try to delete the displayPDF. I have also tried to navigate to a dummyPDF but still displayPDF remains locked.
