rocess of converting a large VB6 program to Vb 2008...(Yes I am late, but that's my third try)I use the navigation keys to move in my program, but as soon I insert a ToolStrip, those Keys (Up, Down, ...) oesnt answer anymore, or very, very, very slowly.If the toolstrip is enabled=false, everything is Ok.I tried "Sub ToolStrip1_PreviewKeyDown" to no avail .
View 1 RepliesI have a group of textboxes for a tab editor. 6 vertcle, 25 horizonal. ( numeric guitar sheet music) I want to be able to navigate them with the arrow keys. If I number them in chronological order from the bottm left, the up arrow key would be "+1", down arrow key "-1", the left key "-6", & the right arrow key "+6". That way I can navigate any possible way on the array. My question is, "How do I do this in code?". ( I have never had a school coarse of any kind in programming-learning VB Express at home.)
View 11 RepliesI really want to make use of the toolstrip and databinding but these two technologies keep conflicting with each other. I think the root cause is something to with the fact that the toolstrip buttons don't recieve focus in the normal way.
I invite you to try the following:-
1. Create a form and put some text boxes a tool strip with a save button on it.
2. Write a query or sproc to get a datatable back and bind your text boxes to the field in the datatable.
3. In the code behind your Save ToolStripButton put some code that makes an arbitrary change to a field on the dataset (it doesn't matter whther this field is bound to a text box or not). eg:-
m_DataTable.Rows(0).Item("CommissionRatePerc") = "0.0000"
4. Put a breakpoint in the save and run the form.
5. Make some changes in the text boxes. Do not leave the last text box but rather click save while a text box whose contents you have edited still has focus.
6. When your code hits the breakpoint, query the value of the data table field that is bound to the text box you were editing when you clicked save - it will still contain the unedited value. Unless you do something about it that unedited value is going to get saved back to your DB.
We did get around this problem by explicetely setting the focus to another control on the form before saving. That worked most of the time because it prompts the text box to flush it's value back to the datatable (nb EndEdit does not work, although you'd have expected it to). However, and this is the reason I suggested you add a line of code that changed a value in the underlying datatable in step 3, if you change a value in code in this way before the value from the text box get's flushed back then it doesn't seem to matter what you do, the user's current edit is simply lost. They will still show in the text box, though, leading your user to believe that the change has been committed when it hasn't. Our final solution is that we never ever change a value in the adtaset in the code behind our toolstrip buttons. That's working but it's a pretty big restriction.
how i can make a button (UpdateBtn) in my toolstrip Act like a NotifyIcon so i can use the BalloonTip features i have looked on goggle all over and cant find a single thing about it (unless im looking for the wrong thing) im thinking it either cant be done or no one has bloged about it yet

View 22 Repliesin my program i have a timer, and every 5 sec (for example) i send a string by serial.i have to read every key pressed between each 5 sec and send a number that tells me what i am sending.what I've done is to send 1 as long as up key is pressed and send 8 as long as left key is pressed and send 9 as long as both are pressed.when i run my program, the first time i press up and left at the same time and i keep them pressed, the serial send me the first time 9 and then ignores the up key and send me 8 always.and sometimes send me 9 and after that always send me 1 and ignores the left key..the point is that vb ignores the first button i press even if i keep pressing it..what should i do to make vb.net takes two arrows keys at the same time?

View 3 RepliesI am making an Auto Typer and it was going all good until I came apon a mysterious problem. When sending the space key or enter key with "Send Keys. SendWait" they come up with their numerical equivalent, 32 and 13.For example, a user types "test" into the textbox, and clicks "{Text} {Space} {Text}" in the options menu. The user clicks start and the output is "Text32Text32Text".Is there any way to just send the keys and make them appear as if you typed them on a keyboard?
View 5 RepliesWell I am trying to make a 2 player game but both players can't move at once unless they tap the keys (can't hold the key down or the other person can't move). How would I fix this as well as being able to go diagonally.Would this work?:Declare a bool value for each keypress below the public class thingy. Then use keyup to turn the bool off and keydown makes it go on. Then for the first player and second player I check if they are on and if they are than go to that direction...I think I would need a timer for that part but I dunno...

I looked into RockXp but that's a third party software.

View 3 Repliesim trying to make a program that only listens to a few keys that the user presses, and if one of them is pressed, it carries out a specified command.for example, right now,i found a keylogger that could carry out my command, but id rather use something else if possible. right now, i have a timer running this:
For i = 1 To 255
result = 0
result = GetAsyncKeyState(i)[code]....
Then, in the textbox1_textchanged, i search for like if textbox1.text.contains("M") or something.problem with this, is im pretty sure its a keylogger, and i dont want to have to have that. also, it does not work in vista.
Found a solution! (should have researched more throughly!)

I usually use standard button and do the settings like causevalidation etc if required.
i decided to use toolstrip and inserted some buttons but end up that it doesn't do the validation for control and also doesn't call leave event of textbox control.
so my question is, anyway to use regular button functionality for toolstripbutton or there is a way to add regular button on toolstrip.
just wondering how i could give my auto typer hot keys, for example they press f1 to start the typer f2 to stop it.

How Do I Make Button.click Event Perform both the enter and period(del) keys on the numeric keypad? [Code] Case Keys.Enter and Case Keys.Separator do not work.
