Apr 17, 2011im writing a program for counting the cash in a till.i have most of it worked out through research on this site and others. im trying to code a text box that allows the user to enter any amount between 0 and 9999.99. I have everything working except restricting user from entering more than 2 digits after the decimal. I could leave it as is and the currency format that im using will automatically round the input to 2 decimal places but this creates a problem if the user accidentally enters an extra digit and the program rounds up. for example if the user intends to enter "23.34" but accidentally enters "23.345" the program will round up to "$23.35" which will cause a problem in the end calculations.here is the code. if someone could explain what i need and where that would be great.

If they click Change button a combo box is displayed that allows them to change what was originally in the textbox. The combobox is updated with whatever was in the textbox as shown below.This all works fine but the user can add something in the combo box that is not in the list which is bad.

Inputting Numbers Into A Textbox And Formating The Numbers?
Jul 30, 2009I 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.
VS 2010 - Ability To Restrict Rows By Certain Date Field
Dec 8, 2011I have a simple query that fills a datatable from an Access DB. There are about 1.7 million records returned, so I would expect it to take a little time. At first, the query was a very simple one, and it took a couple seconds to fill the datatable. However, I really wanted the ability to restrict the rows by a certain date field, which meant a single INNER JOIN to a different table. Having written this, I verified that it was correct by copying the SQL string into the query builder in Access. The query, in Access, took a couple seconds to complete. That was comparable to the time I was seeing before I added in the join.
However, in VB, the query isn't completing at all. After 60 seconds, I get a message about a ContextSwitchDeadlock stating that it hadn't been able to transition or pump messages in a long time. Frankly, since the exact code works fine when I remove the JOIN, this seems like it is either a deadlock internal to the Jet engine, or the error message is an artifact of a very long running query. My question is why a query (albeit a large one) is hanging in the VB program when the exact SQL runs in a couple seconds in the Access query designer, and when I remove the JOIN, the query runs in a couple seconds in VB?

View 19 RepliesOnly Numbers In The Textbox?
Oct 24, 2010I have a textbox where the user inputs the employee number, but it must only accept numbers.
I have coded some lines in the textbox's TextChanged event and almost have it. but when I adjust it to eliminate other characters it triggers itself (recursive). that is not a big problem since the second time does nothing but I dont like the unprofessional way its handled.
But the real problem is that I cant get it to stay "blank" when the user erases all my code always puts "0" on the texbox.
Another thing is that when a non-numeric key is pressed, after the code dismissis it, the cursor goes to the start of the textbox messing up the input.

For the form1, the view is 2 textbox and a 'To' button. when click on the 'To' button, it is direct to form2 which is the datagridview. After selecting the selected numbers, it will display the numbers on the form1 of the one of the textbox. but the problem is I want to abstract one by one of the numbers and append it on the other textbox of the form1.
