I have created a simple calculator in VB.net 2010 and whilst i have basic functions and calculations working correctly i cannot figure out how to use the numberpad as a means of input rather than by clicking on the buttons i have placed on the form for each digit.Is there a simple way of asigning a key on the keyboard to activate a click event of a button on my form?

View 10 RepliesTrying to imitate a Messagebox - in that, a sub will not continue until the user "deals with" the pop up.
For example, in a sub, I want a Form to pop up, and ask a user a question, and give them 3 options. I want to make it so the user must click an option, and then the sub that called it can carry on it's way.
I believe I need a function to make this happen.
i am working on my collage project in which i have an "sensor" which detects weights.specifications : (COM1,2400,N,8)I have added two components Timer and Serialport and set the values timer duration =1000 and added a button and textbox.when user clicks on the button timer1 gets started.and in timer1 i added th code which reads the input from serial.now the problem with the code. the input which i eceive is in ASCII formats(actually some of chars are in ascii format).This is the output i m getting :- 029990so i created a string variable which stores this value.
actually i want only number from that string
ex : 029990 ===> 029990
but i m unable to retrieve that.

I want to make a very small program where the user inputs a starting time and an ending time that is in "clock time (?)" and the program converts it to total minutes in one box and a decimal total in a second box. I have 4 textboxes, 2 are masked text boxes (military time) for input and two are not, for output and the math is coming out weird.
If I put a start time of 0925 and an end time of 1015, the results I'm expecting would be 50 total minutes and .83333 total as a decimal. I don't think I'm converting the textbox input correctly as I'm not getting anything near that. I am using a button to calculate and another to clear the boxes, just FYI. Also, I'm not sure what to do about any times that span the noon hour except to use an absolute value.
Public Function Time()
Dim StartTime As Double
Dim Endtime As Double
StartTime = txtStart.Text
Endtime = txtEnd.Text
txtDecimal.Text = (Endtime - StartTime) / 60
txtMinutes.Text = Endtime - StartTime
End Function
I am wanting to write an application which opens a delimited text file (either comma, pipe, colon, semi colon) and displays the file on the form. The same feature is in Excel when you import a data file. After selecting the file it shows the contents and you can choose the delimiter. Once the delimiter is chosen the data shown reflects this and updates to show the correctly formatted data.

Private Sub todayMonth_Validating(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles todayMonth.Validating
Dim tb As TextBox = DirectCast(sender, TextBox)
If Convert.ToInt32(tb.Text) >= 1 And Convert.ToInt32(tb.Text) <= 12 Then
tb.Tag = True

Actually, I wanted to validate the todayMonth textbox just to input number between 1 to 12. The problem comes out when I do this procedure : Lets say I input an interger 11 and it passes the validation and proceed to another textbox. Then I click back to the todayMonth textbox, it shows this error :
"Conversion from string "" to type 'Integer' is not valid."
I don't know why my value in the textbox is "null" or empty . I still saw the value 11 on the textbox.
I am creating a project with a maximized per-pixel alpha form. However, the normal input events (MouseDown, MouseWheel, KeyPress, etc) are never raised. I've been able to create some bare-bones functionality by overriding the WndProc method, but some things elude me. For example, I want to detect mouse wheel scrolling. When I check for the mouse wheel message, it works fine. Then I try to use the GetLParam function to get a MSLLMOUSESTRUCT with the scroll data. However, when I try to use it, I always get an error:"Attempted to read or write protected memory. This is often an indication that other memory is corrupt." What can I do?-Must Program! Error: Not enough time to program
View 1 RepliesI am creating a form in vb.net and i want its size to change the form as soon as the user inputs the desired number of items. In my form I have two combo boxes: one for number of items and the second is for the choices, then when the user choose 5 items 5 text boxes will appear and if the choice is 25 then 25 text boxes will appear. Is there any way that I can change the form based on the input and number of text boxes?

I have VS 2008 and am working in VB.Net forms.I have a webbrowser control where I am trying to control input fields that are dynamically created. If a text field has proper handles such as id and name tags there aren't any problems.For example, I am trying to work with twitter for posts. I know twitter has an API but I want to work with many similar systems and want to avoid the API as its case specific and I want to scale things within the VB.Net form. The login fields for twitter are easily handled, however
the posting field once your logged in is just a text area with a class. There is a tagname but I have been unable to post using the tagname element.

View 3 RepliesI'm developing a windows forms application using VB.NET. I'm currently working on DataReport (by Microsoft, not Crystal). Everything works fine when using DataSet as DataSource. But I have a question on how am I going to put data to my DataReport from a user input? Preferably when the user is on the act of printing(clicking the print button in the ReportViewer), a Form will pop-up and ask him for input. That input I'm talking about is random names of people, and we don't have to track their names so there's no reason to put it on the database.
Here's my simple setup:
MainForm.vb (Form)
MyReportViewer (ReportViewer)
MyReport.rdlc (DataReport)
[Code]....
If it is impossible to do it on the act of printing. Maybe on the MainForm_Load event or before the generation of report can do.
