View 7 RepliesI have Visual Basics 2008 express and I tried to make a autotyper, so this is my
Button1: Timer1.Start
Timer1: Timer2.Start
Timer2: SendKeys.Send(Textbox.text)
Button2: Timer2.Stop
So it was my first try ever with VB and it kind of worked... Only 2 problems;
1. Button 2 doesn't really work, I have to click it really many times, then go to a different window, then click it really many times again, in the meantime it keeps on spamming
2. How do I make my autotyper press enter every single time after the textbox message was typed?
Is there also a way to make it so that there can only be numbers in a certain textbox?

Are there any possibilities on doing this with Visual Basic 2008 Express. Do I even need to create my own control? Is there something else I can do?

View 2 Repliesbest way to check if a textbox has only 4 numbers and isNumeric, for example i need to enter postcodes.I currently have:
If CDbl(txtPostcode.Text) <> 4 Or Not IsNumeric(txtPostcode) Then
MessageBox.Show("Postcode must be 4 Digits", "Error")
But the message box comes up regardless of whether there is 4 numbers, letters, or anything in the textbox. Its also used in the leave function of the textbox.
as seen in picture I have in "TextBox1" some numbers and I would like to have a detailed information on "TextBox2" (marked with red) when I pressed the "Process" button about them. In other words, I want the application to tell me how many numbers in total are inside "TextBox 1" and also to tell me if there are some duplicated numbers if it finds some of course?
View 1 RepliesName: RyDeR (RyDeR is what I typed in the Textbox) Age: 17 (17 is what I typed in the Textbox) But now I have another Textbox but I want that this textbox automatic changes with what I type in the first boxes. Example:
His name is 'RyDeR' He's '17' years old
.. Like this and if I type something else, it must change to in last textbox.

I have a simple question regarding the KeyPress event. I'm trying to make it to where my TextBox on my form can only accept numbers 0-9, backspace and '.' /without quotes. I've successfully got it to accept numbers 0-9, accept backspace, I'm just wondering - what line do I add so that it can accept periods as well?
Here's my

View 1 RepliesI am working on a "de-bugging" back-end sorta thingy for my program, and I have a "dll" that executes most of the work for the program. For the ease of tech-support, I plan on trying to impliment a hidden back-door into the engine that is password protected and activated by a key-press. What I want to do is:when the enter key is pressed, have the dll run the sub that is listed in the enter key, for example:
In the dll:
Public Sub msg(ByVal text as string)
MsgBox(text)

I just D/L VB express 8, and I'm trying to learn how to use it. what I'm trying to do is write some code that:takes a number into a text box (textbox1.text)do some simple calculations with that number when I press a button (button1)display the results in a second text box 9textbox2.textThe first problem I am having:The numbers are in the "milli" range, meaning to the power of negative three, so 10^-3 = 0.01 I do not want to enter 10^-3 or any other exponent into the textbox, I am simply entering in 10 because all my units will be in milli. I've tried using exponent and scientific notation but it doesn't calculate correctly. I've done a "work around" to get it to do what I want, but there has to be a simpler way to achieve the above results without. for example, the user enters 10 into the textbox, the button multiplies 10^-3 *30, as a crude example, and stroes that value (say, B=10^-3*30) and B is DIM B as Double.
Problem number two:Error checking. I need to validate that only numbers can be entered into the textbox, or else the program will display an error message (messagebox). I can achieve this to some degree with sample code from here and other places, but, some of the code does not take into account that some numbers have decimal places (I have foud code that does, and it does work), but if a users enters, say the letter "E", it crashes the program. If the user enters "10.3Z", it crashes the program. I cannot seem to code for the last case, a mixture of numbers and letters to get an error message box.
I've created a new datasource dtsLogin containing an ID, username and password. my problem is how can you check if the username & password typed in the textbox are the same as the one on the Access database? I thought maybe using a rowfilter but I'm not that good in ADO.net.

I created a DataSet using the DataSources wizard. I can display the rows of each Datatable one at a time. But in this case, I needed to add a new DataTable (newDT) using the Add New Table Adapter control(?) on the toolbox. newTable is derived by JOINing three different existing tables (or, dataTable) in my DataSet designer. The query works fine and returns all the data as expected. Trouble, if I try to display the rows of the newDT on textboxes, I get a NULLREFERENCE Exception.

I would like the autocomplete list of a textbox to be the words that the user has previously typed and saved. For example if they enter "dog", "cat" and "fish" I want the autocomplete suggests to show these three options. So far my Code only shows the last user input. I expect there is an easy solution as I am new to all this, but I can't seem to find it on my own.

View 14 Replieshow to count the lines in textbox1.text (with multiplelines). I don't need to count each character. I only need to count each line from top to bottom in textbox1.text (multiplelines) and I will use Label1 to display the numbers.
example:
1-pauljaones
2-tommyperrry
3-marktoms
4-Jonessmith
5-paulwhite
Obviously this is 5 lines and that's what I need to count.

View 1 RepliesI have a tab control application, each tab loads a particular user control and each of those user controls will then add other user controls that are used amongst other the user controls. For example, I have an "ucQuotes" page and an "ucInventory" page, when the specific tab is selected, the "uc****" user control is loaded on that page, and in the case of "ucQuotes" and "ucInventory" they both use a control called "ucPartNumber"; a user control consisting of a combobox, textbox, and button. I have no issues reusing the shared user controls, in this case. My problem arises with my "ucQuickPrice" control, as it is always present at the bottom of the tab control form (separate from the tabcontrol, but on the same form), and it too uses ucPartnumber.
Here's my issue, as I type into the ucPartnumber combobox, the text I type does not appear in the combobox, it appears in the textbox of the ucPartnumber control that is being used on the tabcontrol page. There are no shared instances of ucPartNumber, nor do I have this issue between typing on one tab page and the text showing on the user control of another tab page.I tried just creating the ucPartNumber controls on the ucQuickPrice control, not adding a new instance of ucPartnumber on the .Load event, and the issue persists.
The combobox(s) in question are bound programmatically with about 40,000 items, ".datasource = dataset.tablename" not to a bindingsource. Autocomplete is set to none, I added code to utilize tool tips and the basic combobox filtering functionality. Is this a bug, or is there something I'm neglecting? I'm about 95% complete with this application, and this just happened today. I made the decision, to just reuse the ucPartNumber control on the ucQuickPrice control (originallly it's size and orientation would not fit, but I added some coding to detect what parent is adding ucPartNumber and to change its appearance accordingly). Before, I made this change, I did not have this problem. And, in trying to go back to how I had things set up before the change, the problem will not go away. if the whole control within a control verbage I used is a bit confusing, let me know and I'll try to better explain what is happening. At this point, I'm going to close and reopen vbexpress, as when I started this ordeal, vb started acting weird and wanted me to save all my work, it usually does this before locking up.
I am deleting a row from a row that is currently selected on a datagridview.I am using a Typed dataset and my datagridview is bounded to a binding source.However, I think my technique is not the best, even though it works.
Dim drDelete() As DataRow
' Get the value of the PK from the currently selected row
Dim drv As DataRowView = CType(bsAddressBook.Current, DataRowView)
