Has anyone used a system wide hotkey and notice it no longer works? But the program is still running fine. When I run my program and it starts the hotkey, sometimes it will work fine all day, other times within 15 minutes I press the keys and the program does not react to it. I am using the keys Control-F2. Here is my

I am having issues with my program. It should update every time i click the button, but it runs through perfectly on the first click, after the first click it does nothing.This is a UDP Program, where the client sends a packet with a sequence number and payload which are separate items in the packet. The server receives the packet, reads the sequence number, and then sends back the next sequence number the client should send.The client then receives that from the server with the same payload.. And then should change its sequence number to the one it recieved, and send that to the server..The client works up to where the client updates to the sequence number it receives from the server.. But both show no effect on any clicks after.
Heres my Client

What I want to do is to make my application to SendMessage to another application. I can send message perfectly when i set keys.F1 or F2 etc in code but, I wonder, is it possible that user change this key in runtime? I was thinking about doing something like:
If combobox1.text = "F1" then
SendMessage(pHwid,WM_KEYDOWN, Keys.F1,0)
elseif combobox1.text = "F2" then
SendMessage(pHwid,WM_KEYDOWN, Keys.F2,0)
etc...
But I have 19 usable keys and alot of events with SendMessage function so code will be so big and there's possibility for slowing application. Is there anything that I can do, like...
Dim hKey as STRING? INTEGER? WHATEVER...
SendMessage(pHwid,WM_KEYDOWN, Keys.hKey,0)
?
this little program so a user can choose a hotkey and then set that hotkey with a sentence. The aproach I took to using the values in the combobox to set RegisterHotkey works, but I feel like there is a much simpler and less time consuming way. Basically It too about 700 lines of code to set up 10 comboboxesHow would I go about making a global hotkey with NO modifier such as alt or control.

i would like to ask if it is possible to change a hotkey to another hotkey in vb.net?.eg. when keys.k is pressed it will output as if keys.a is pressed..when I press k in a keyboard it will output letter a in any textarea etc.it will go on as long as the program continue running..
for the reason that i would like to create a program that will change a keystroke to another keystroke..anyone familiar with a dota hotkey/warkey?..its just like that..when I press alt+q it will output the num. 7 in the numlock
alt+q = 7 ; alt+w = 8
alt+a = 4 ; alt+s = 5
alt+z = 1 ; alt+x = 2
and so on..its just like that
This is in a RichTextBox. I'm making a string of sports stats and I need to have them aligned neatly in the RichTextBox. Here is an example: str = "12/24 (tab) 225 yards (tab) 2 TDs (tab) 2 INTs" When I use the vbTab constant in place of (tab) I run into problems as the size of the text in each column can be different which makes the tab not balance out correctly.

Been trying to figure out why my progress bars (one in the status bar when the main window is open and the other in a window by itself before the main window is shown) go up most of the way, then stop till the processing is done.I have refresh in there where the action takes place, and that made it work mostely.Basically I'm loading a file into a string, then while in a loop, I'm processing the file by lines. I have a function that retrieves a line, then it does a:
pbProgress.Value = pbProgress.Maximum - sWork.length
pbProgress.ProgressBar.Refresh()
StatusBar1.Refresh()

I'd like you filter some results in a grid, and i want the user to be able to type a value into a textbox, and then the grid will be filtered by that value. I don't need help with the grid or how to populate it. My question is in regards to the textbox; How can i tell when the user has stopped typing so i can automatically load the grid? I thought about doing a refresh automatically in the TextChanged event, but that seems silly since the user could still be typing more characters.

I�ve had success using the GET method to retrieve a series of web pages but my new challenge requires me to use a POST > GET combo. I can get it to work once just fine but no more. I get the feeling that something isn�t closing or completing properly. When I try to do the second GetRequestStream() I can see from my sniffer app that nothing is being sent so when the next command to stream the POST data to the request session it fails. I removed it all from the loop and simplified it as much as possible. Can someone tell me why it fails?
Also as a general question is my tack or reusing WebRequests viable? Or is there a �best practice� for looping a POST > GET combo? I�ve been assuming that since nothing in the WebRequest changes besides the post data I�m sending, even its length remains the same, that I should be able to re-use it.

I have a program that uses the mouse to find window captions. I made a test program that just does that and it works fine. I copied and pasted the code into my other program and it doesn't work. The mouse position changes, but it will only get the caption of a window if it is at the top of the screen. It seems that only the Mouse.X position is changing, but I put the MousePosition.X and Y in a label and they are both changing. Can anyone explain why this is happening?

When I run it, it works because I have MsgBox() in there (at the end of the script). As soon as I remove MsgBox() it stops working properly, why?
What it should do: When the program loads, it will call my sub, the sub will check to see if the two files exist, if they don't exist a folder dialog box is opened and you select the folder that they are in, it will then call it's self again and do the same thing. If the files do exist it should continue with the program.
The Problem is, that it only works the way I want when I have the MsgBox() function there otherwise it only works if you select the correct folder the first time the dialog pops up.
I've been working on a program that generates a batch file, then when you press a button, it executes that batch file. There are multiple batch files attached to each item in the list box.
[code]...
The only thing that it does when I press the button, is starts the batch file, then goes to function searchtitle, which executes the batch file again when it finds out it didn't work properly.The button text doesn't change, none of the items are being added to my first list box, and I can't do anything to the window after pressing the button. It constantly opens the batch file every 5 seconds or so.
I have an app that moves the mouse, and does a click on the screen however, it seems to work great on windows XP machines, and when i try it on my windows 7 box, the window dosent close, or do anything..
I typically will hit my "execute" button, that will minize the window, then i place my cursor where i want it to go, and hit space bar, and it should move my mouse up a few spaces, click, and move to the next.. But again, winXP it works fine, win7 dosent do anything.

View 2 RepliesI am running a website for a F1 racing game, where users can submit their laptimes and compete with each other for the fastest time.
I am now trying to have my website create an image of the top-5 users every... 5 minutes or something, and copy it to the webserver somewhere I can link to. This way the image under that link will update with the latest information every 5 minutes.
To layout the times (these also include the position (1 to 5), the username, the platform, the time of course, and some more details) I am using a DataGridView. I could take the long route and layout the specific 'columns' manually, but I thought using a grid was far easier. I simply set some properties of the grid to make it look nothing like a grid (basically hide the column and row headers and grid lines and give everything the same backcolor). Then I load the times into the grid, and take an image of it using the Control.DrawToBitmap method.
This works fine, but it returns the entire grid. This is a problem because I made the grid extremely large (5000x5000) so that it can always accommodate the times regardless of the length of the usernames. So, the image I get is 5000 pixels wide while it only contains data in the first 500 px orso.
I am currently using the GetRowDisplayRectangle and GetColumnDisplayRectangle methods to figure out the part of the grid that actually displays the times, and use that to cut the image down to the portion I need.
But here's a problem: these methods only return something when the grid is on a form that is currently being shown! I am already giving the grid a parent form (even though I am just creating it in memory and it doesn't need to be displayed anywhere) because otherwise the data wouldn't load, but I was never showing that form. Now it turns out I do need to show the form, very briefly, in order to figure out the area that I need to take a snapshot from.
Remember that this is all happening on a webserver, so I'm not absolutely sure if this is a problem. Is it ok for a webserver to have a form popping up and down every 5 minutes? Or will this cause problems? I honestly don't know but I don't think it's a good thing. Moreover, it also pops up on my own machine when I'm testing, and it's damn annoying.
So my question is basically twofold:
1. Maybe I should ask this in the ASP.NET forum, but is it a problem to show a form briefly every 5 minutes?
2. Is there any other way to get these Get...DisplayRectangle methods to work without having the grid on a physically visible form?

I am not stuck with the code side but rather what seems an issue when using VB and creating well verifying an Twitter Account. I have tried to explain as best as possible but please ask if you need more info
I am currently well on the way to finishing my Twitter Account Creator which also verifies and completes the profile fields but I have encountered a problem and for once not a problem relating to the code side of things at least I don't think it is.
At the moment for testing reasons I have 2 buttons one which creates the account and a second which verifies the account now I am using incognitomail.com (temp email provider) and have 2 web browsers running within my VB program. 1 is for Twitter and 1 is for Incognitomail.com I have no problems clicking and navigating to the verify link and then logging in to verify the Twitter Account but it never verifies and I cannot figure out why.
Say I put another text box and used it to navigate to url's on web browser 1 (twitter) and copied the verify link and put it in the text box it navigates I login and its the fine the account is verified but if I set VB to navigate (can't click because it opens in IE and not within the VB web browser) to the verify link it never verifies I have even tried making the text box fill and then navigate via that just as if a human was doing it but still no luck.
Does anyone have any idea as to why these Twitter Accounts are not verifying when the VB program performs the navigating to the verify link then login but if I do it myself i.e copy the verify link put it in the text box which navigates the web browser then it verifies fine?This is the one step standing in the way from my program being about to create and verify accounts and will not cost a fortune as this was a personal project to counter the lack of Twitter Creators which both work fully and are cheap.
I'm developing an application in vb.net. You drag any type of file onto the exe, and a window pops up with some options for the file, then it saves the file to a different location, works some SQL magic, etc. It works great for the most part. The only issue I've found is that if the path of the file contains any spaces, the application will crash immediately with the error window:[URl]..I'm using: Private filename as String = Command$ This is located right inside my form's class declaration, not within a sub/function.Without this line, my program runs fine (although useless, without accessing the file).I've also tried (I think this was it, I don't have the code with me at the moment): Private filename as String = Environment.CommandLine So, in vb.net, is there a way to drag a file onto an exe and use that path name, even if there are spaces in the path name?
