Forms :: Process MainWindowHandle - Simple GUI Form To Hide / Show / Minimize / Terminate / Force Terminate
Sep 11, 2011I have a simple GUI form to hide / show / minimize / terminate / force terminate Processes. i can do all well but for show and hide i need the MainWindowHandle to show or hide it
So here is hide process code:
Dim Proc As New Process = Process.GetProcessesById(List.SelectedRows(0).Cells(1))
Dim hwnd = Proc.MainWindowHandle
ShowWindow(hwnd,0)
If i try the same with show code:
Dim Proc As New Process = Process.GetProcessesById(List.SelectedRows(0).Cells(1))
Dim hwnd = Proc.MainWindowHandle
ShowWindow(hwnd,9)
The MainWindowHandle become 0 cuz its hidden is there is any other way to get the MainWindowHandle of Process ?

Terminate A Program Immediately From Try Catch?
Jan 19, 2010I am trying to end a program immediately when a critical exception is caught. But I am finding that code after my Try/Catch block is executing even though the code withing the Catch block is executing, and that Catch code is calling Me.Close.
I suspect it has something to do with background .net threads or something, but I have no clue how to deal with those kinds of issues. How can I stop the program as quickly as possible? If code after my Catch executes, it will (and does) throw lots of uncaught exceptions later. Currently, it is not feasible for me to try to catch all the other exceptions. I just want to report an error and end the program.In my form load routine, I create and set up a number of objects and arrays by calling various subroutines.The success of most of the subroutines depends on the sucess of three subs in particular, which are called early on. If one of those three fails, there will undoubtedly be a number of hard to trap exceptions later on in the load routine.

Quickly Detect USB Key?
Aug 18, 2010I want to develop an application using VB.Net to detect the arrival of USB Key once it's plugged into the USB port. I used a method by getting the list of all drives in the computer and then I check whether the type of the drive is "Removable Disk" and "Is ready" or not!. By using this method, I can figure out which drive is Removable drive. BUT I get confused with the FLOPPY Drive because it's also a type of Removable drive.

Encrypt Large Files Quickly?
Jun 24, 2009I am working on a application that stores videos, images and files. I would like to give the user the possibility to encrypt them. I am tying to use AES to encrypt them but the problem is that the decryption takes to long.I was hoping that the loading time from the hard disk of the encrypted file was far longer than the process of decryption of an image for example but i was wrong
So if i try to 1) load the image 2)decrypt it and 3)load it in a image control it takes 15 times more time that loading the original file not encrypted

VS 2010 How To Format String Quickly

[2008] Search Quickly In An Array?
Jan 14, 2009How can I perform a very fast search in an array, that finds a substring of an entry in the array? As an example, let's say that I have an array containing these objects (as strings):
[Code]...
What I then want to do, is to find any matches matching (as an example) the letter "S". I want it to display all the entries with the letter "S" in it. I don't want to use loops of any kind, and I prefer using things such as the array's inbuilt BinarySearch function. However, it seems like the BinarySearch function only compares from the beginning of each item. I'm using very large arrays. So a fast method is really needed.

View 5 RepliesCheck Folder For Modified File Quickly?
Oct 10, 2011I have a folder that can (hundreds currently) but upwards of 10's of thousands of files. I have a program that gets all file names, and sorts them based upon set criteria and displays them in a treeview. My issue is right now a few hundred files moves fairly quickly when getting files name (path.getfiles), sorting, and returning sorted list for further search and display. My concern is when the number of files starts to increase, alot of these functions will take exponentially longer to perform. Especially my organizing function.
Because my files are part numbers <PartNum><Rev><SubRev><ManuNum>.<extension> I first sort out all different Part numbers first making the list manageable (maximum of a few thousand). Then as you choose a part number to work with, it retrieves all files associated with that part number (maximum of a few hundred).
My concern is everytime I need to look for a file in anyone of those steps, I have to import all file names, search and return correct file path, and Im sure this will become slow as the number of files increase. I dont mind having it do it once then update the list as needed. So I was thinking import and sort all file names at load, and check every so often for and files that might have been modified recently and just update it's entry in the sorted list. But this means my program has to stop, and check all files for changed "modified" time, which too will be slow-ish.
How To Draw Readable Tiny Text Quickly
Jul 28, 2010In developing a flash-based memory manager, I need to be able to view large quantities of data. With my eyes and monitor resolution, I can read hand-drawn 3x5 letters on a 4x6 matrix without too much difficulty, but none of the system TrueType fonts render optimally at that size. I've tried writing code to draw font shapes to off-screen bitmaps, and then use DrawImage to copy those bitmaps to the screen, but I can't get good performance. This is for development, not production, so performance doesn't have to be absolutely optimal, but I don't want to spend too long waiting for screens of data to refresh.
What would be the best way of either making .net display a font which is pixel-perfect what I want, or else building a bitmap out of lots of little pieces quickly? I'm using vb.net, so I can't simply generate a bitmap as a byte array and pass that to the Bitmap constructor unless someone can show me how to convert an array into an IntPtr.
Multiple Forms - Quickly Opening All Tabs?
May 11, 2010I'm just having a small problem with tabpages. I have a program that have multiple forms (on startup they are all created and hidden, except for the one being viewed by the user). When the user open one particular form, I has a tab control with two pages. I also have a toolbar. when the user click a menu option, I call a method that assigns all my controls to a variable (to be used in an insert statement later).
Here's an example of that Sub:
Public Sub SetValues()
'page 1
DateCreated = Date.Now
DateEdited = Date.Now
DateCompleted = Me.DateTimePicker2.Text
[Code] .....
The problem is, the controls on the second page cant be "seen" (this is confirmed by placing a msgbox in the above sub, which comes up blank) until the user open the second tab, at least just once. Then its ok. I know I can just run a small method to quickly open all tabs, but is there a reason this is happening, and a better way to do this?
