I am using vb.net framework 3.5. I want to lock input devices like keyboard and mouse from my application. Is their is anyway using sendkeys or any method to lock?
View 5 RepliesMy code behind is VB.NET. I use ASP.NET UpdatePanel like the following. However, after the post-back, it locks TextBox controls , I cannot type anything, except when I move the mouse over and click on the TextBox.
why it locked all TextBox controls after the post-back?
Here's why I use UpdatePanel:
During the post-back, after inserting data into DB, set all TextBox text property to String.Empty After the form is submitted, the Panel pStudent should be refresh , not the entire page and the TextBox txtId should be in focus again.
here's the mark-up of the ASP.NET page: [URL]
Basically,I had a button in my form1,when I click it,then form2 will be display...Now I would like to lock form2 until a button in form2 had been clicked,then only I can do anything in other forms...I means form2 must be closed before I can remain to form1.
View 1 RepliesI have my main form then a progress bar form that is shown when the program is running. I simply want to keep the progress bar form on top of the other form and make the other form so it can't be changed.
I've tried form2.showdialog, but that stops the code in the main form from running so it's no good.
form2.show(me) just keeps form2 ontop of form1
me.topmost in form2 does the same as the last thing
setting the form1.enabled = false isn't something I want to do since you can't even move the form when it's like that
So really I'm at a complete loss here
also how can I get the progress to start in the center of form1? There is a setting in the form properties but is doesn't seem to work.
after i set the windows form lock to yes and press f5 fordebug mode , i can still drag the form around the screen

[Code]...
The form is full screen, but I can shift the location. I do have a dual screen system. The application goes full screen on the left most screen. This does this inside the development environment and using the EXE. What am I missing? I thought Locked is suppose to prevent the form from moving.

I have a Dialog which I'm calling via Loading.Show()Can I lock the position and location to the parent form? In such a way so if the parent is minimised or moved, the child will stay centred to the parent?
I was using ShowDialog() but this obviously stops the parent from being accessible. This is being used to display a progress gif. (Child is 50% opacity)

View 2 RepliesI have a slight problem With an enumaration of child controls on a form. The following code will not get but about have the controls that are on the form. The controls show that the count is correct but when it goes through the loop it skips over some of the controls. If you run it through the enumeration two or three times it will get all the controls a few at a time. The solution uses two forms, one that has the controls and the other that labels are made and displayed on. The Tx is just a index to add a number to the label.name and rename the label. So each label is identified seperately. This works for all the the controls that are seen in the for each loop.

View 4 RepliesOk, so I'm writing a basic windows form application in VB.net as you do and need to be able to raise keyboard events based on data received from the serial port. I'm able to receive the characters that I want (lets say a lower case c) and display them. Its also easy enough for me to find the keycode. What I want to do though is tell windows that key "c" has been pressed. The application is paired to a bluetooth terminal, I wanted to have the experience of writing the code behind this myself rather than using another library although it seems I've failed already. How would I go about doing this?

I have created a virtual keyboard like the "Windows onscreen keyboard". So, I have used the method sendkeys.But if I click on the button, it doesn't write nothing.

View 10 RepliesInside a form, I would like to display a pdf file which is already available in my resources (template file "untitled"). In this pdf file, I have some fields which get their values from some texboxes in another form. My aim is, when the user triggers the button to call this form, it should insert the values inside the pdf file and display the output pdf inside the form.I have written the code to an extend but could not finish it myself after my many trials... Now here are the two things I cannot manage:I can use a directory to read the template pdf "untitled1.pdf". But my aim is to use the file inside my resources. can save the output file in a directory but this is not I want to do. I want to display the output pdf.
