IF Statement To Check If Textbox1 And Textbox2 Are Blank - Notify User That Must Insert A Value
Jan 22, 2010
I am practicing abit with For Loops. My code works fine which i am very happy about. I have now moved on to inserting an IF statement. I want the IF statement to check if my textbox1 and textbox2 are blank and if they are to notify the user that they must insert a value. I thought this would be quite easy to do however i think i was again ignorant to the coding! See below.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim answer As Integer
[CODE]...
I want to concentrate on the IF statement only as the For loop is working just as it should. When i run the program and leave both textboxes blank and hit the button i receive an error saying 'Conversion from string "" to type 'Integer' is not valid.'

I'm running some if statement but I have hit a brick wall with what I'm doing and trying to do. If textbox1 has a value then I run different coding to if textbox1 and textbox2 have a value - Textbox1 will always have a value. [Code] What I'm trying to do is add an additional statement if both Textbox1 and Textbox2 have text, then to run code 1 if the last four characters in textbox2 ends in .jpg else to run code 2. [Code]

Let's say that you have a texbox labeled TexBox2 and you don't want it to be seen when the program runs because TextBox1 pulls information from TextBox2 and it shows up inside of TextBox1. How would you go about doing this?

I have a login form that I made. The user enters a username in textbox1 and then enters a password in textbox2. The user then hits the submit button (button2) and from there it works beautifully. The problem is, I would also like the user to be able to hit the "enter" key after they fill out the password textbox (textbox2) and have it be like they pressed the submit button. When the user hits enter right now, the form hides.

I am basically trying to create a basic math calculator, the basic inputs are in TextBox format. I have made the basic calculator ok but would like to have a MsgBox pop up if TextBox1 is > TextBox2 these are both TextBoxes which have data entered in them. Hope this explanation makes a little sense. Below is my attempt at this!
Private Sub MsgBox_Load()
If (Val(TextBoxDPID.Text) > Val(TextBoxDPOD.Text)) = MsgBox("DPID can not be Higher then DPOD",

Here is an example of the .fil or CSV I am reading from. The numbers in this example are arbitrary and only serve as identification.
// A, B, C, D
000, 9.000, 9.000, 9.000, 9.000
0.000, 0.000, 0.000, 0.000
[code]....
I would like to display the values of 1.000 and 3.000 in Textbox1 and TextBox2.Next, I would like to multiply the values 1.000 and 3.000 with variables Y and Z to give products J and K.I would then like to display values J and K in TextBox3 and TextBox4.Finally, I would like to take the CSV file and replace 1.000 and 3.000 with values J and K, respectively, and save.

I'm stuck with how to copy all lines from textbox1 to textbox2, in 1 Hz. This sounds maybe odd, but my thinking was to do it in a timer set to trigger every 1000ms. textbox1 Line1 should be appended to textbox2 line1.....until theres no more lines. Of course a loop will do this, but right now I'm stuck. This will of course add all lines every time the timer ticks:

How can I get the sum all the values a user enters into TextBox1 to display that sum into TextBox2.The user is going to enter one value one by one. The user enters '1' into TextBox1, therefore, TextBox2 should display '1'.If the user than enters '2' into TextBox1, TextBox2 should display '3'.If the user enters '2' into TextBox1, TextBox2 should display '5'.And so on.TextBox2 should only display one value at a time, not one after another.I am using double because I need decimal places.I have a ListBox1 where it displays all the values entered by the user in rows one by one, but I prefer not to use the ListBox1 to get the sum of all the values entered in TextBox1 and to have TextBox2 show that sum. Because in that ListBox1, I have few other things in there, like Strings, which will not allow the sum of all the values entered in TextBox1 to be calculated and displayed in TextBox2.Not sure if this matters or not, but I thought it might.So only need TextBox2 to have all the values entered in TextBox1.If 1 was entered in TextBox1, TextBox2 shows 1.Then 2 is entered in TextBox1, TextBox2 will show 3.

I have two textboxes on separate ajax tab panels. I was trying to setup a javascript onkeyup attribute to set the value of textbox1 to textbox2 or vice versa depending on which they typed in. If the textboxes are not on the tab panels then it works just fine but I cannot get it to work when the two textboxes are on separate tab panels. Here is what works outside the tab panels.
Public Function AddOnkeyAttributesControl(ByVal ctrl1 As TextBox, ByVal ctrl2 As TextBox)
ctrl1.Attributes.Add("onkeyup", "javascript:form1." & ctrl2.ID & ".value=form1." & ctrl1.ID & ".value")
ctrl2.Attributes.Add("onkeyup", "javascript:form1." & ctrl1.ID & ".value=form1." & ctrl2.ID & ".value")
End Function I just call this function with the two I want to link as I said it works outside the ajax tab panels but not on the tab panels. i am sure it is something to do with the way that the tabs are rendered but i don't know where to start.

I've got a basic email application set up, and I'd like the "To" field (TextBox1) to be an autocomplete textbox.I'd also like the user to be able to edit what their contacts are, and so be able to add named to the autocomplete suggestions.I can get TextBox1's autocomplete suggestion to come from TextBox2's current Text - however this means I can only have one name as a suggested contact.Ideally, something like a list box would be ideal, so the user can add and remove names, and this list would then provide the source for the autocomplete.
