So I am playing around with the resize event. My form is 500 wide, my button.left is at 100. If I use:
Dim int As Double
int = button1.Left / Me.Width ' this = 0.2
'resize event
'Button1.Left = (int * Me.Width)
TextBox1.Text = (int * Me.Width).ToString
The number in the texbox is correct - proportion wise, but it won't set the button1.Left to this number. I'm sure this is because int is a Double where .Left is an integer?
I have set up a Textbox Resize event, but when I execute the form, it doesn't allow me to change the textbox size. I'm not sure what code to show; this is a VB.Net book exercise that I'm running in VB 2005. [code] I have tried setting the Border to something beside 'Fixed'. All resize references I have found refer to Forms or tables. Is there a property that allows users to resize a textbox?

I want to resize the form size on button click event.
View 2 RepliesI am writing a program that programmatically generates buttons based on database information. The buttons CANNOT be more than 75,75 in size. The problem is, if the text is longer than 9 characters, it moves the rest on to a second line. How can I make the font size automatically adjust to have larger text if it can, and if not, have smaller text to fit on one line
View 1 RepliesI'm doing an application for a school to help them keep track of student attendance and because I'm rather new to VB 2008 .NET I'm sure I'm missing something simple.see the screen shot and attached sample application showing the problem I am having.
The screen shot shows 3 open forms. I'm not able to get the value from the 3rd open form into the Student ID textbox of the 2nd form even though my messagebox shows a value is really in there.The attached application has 3 forms similar to the production application I'm writing which also includes 3 forms. Could you look at the application and tell me what we are missing to get the textbox data in the 2nd form to show up?
I created so many listviews in my project, that im too lazy to add to each listview a resize event with percentages. Is there any other trick, who just scales the columns so as they are?
View 3 RepliesI'm starting work updating an UI for one of my company's applications and I'm running into a sticky issue. The parent control contains several panels, each of which can be turned on or off depending on user input.
The final panel in the user control contains another user control which gets resizes according to a toggle switch. Essentially, it "opens" up more information.
While the child control (ChildControl) is docked to Fill inside the parent control (ParentControl), when I add height to ChildControl I can't get ParentControl's height to get updated as well. Currently I'm handling the ChildControl.Layout event in ParentControl but I can't seem to reach that code. To resize ChildControl, I'm calling Me.Height += 200 in ChildControl.vb.
I am having one heck of an issue with a webbrowser control I am using. As part of my job, I am working on creating a tool to automate an older system that we still use. The part that is being automated is web-based, and the group running the automation does not have access to any automation tools like QTP. In order to give them something they can use, the idea was to build an application just for them. In this application, I have everything working perfectly, with the exception of the most important part: the entry of a policy number. The policy number goes into a textbox, and then the user presses a button. A part of the automation sequence involves the use of a timer.
If I manually navigate to the appropriate page and put the .SetAttribute statement in a button action on my form, it works perfectly fine. However, if I put the .SetAttribute statement anywhere that is being controlled by the timer ticking, it does not work.So, this works:
Private Sub btnTest_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTest.Click
Me.wbPrestige.Document.Window.Frames("WORKSPACE").Document.GetElementById("policynumber").SetAttribute("value", "1234567")
End Sub
but this does not:
Private Sub timerLoad_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles timerLoad.Tick
Select Case currentStatus
Case Status.wait_for_retrieving
[code]....
As a note, I do not have the Select statement in the Tick action; I have it in its own little sub. However, since it functions the same way no matter where it is, and to save space, I combined everything here. Also, at the time of the timer firing and setting things into motion to enter the policy number, the page is already fully loaded, so I don't think it is an issue with that, though I could be wrong.
It does not throw an error. The "1234567" above is passed in as a string, and doing a watch on it at run-time does show that the value is actually in there. It just seems like the .SetAttribute is not registering on the textbox. I have tried a few things ranging from "what-if" all the way to "that-is-so-dumb-it-just-might-work." Nothing seems to do the trick. I have tried sleeping everything for a few seconds just to see if there was an issue there. I have tried issuing the .SetAttribute command a few times in a row thinking it just wasn't taking the first time. Since setting .Focus() didn't seem to work for it, I even went so far as using SendKeys to move focus to the textbox on one attempt and API calls for mouse clicks (to click inside of the textbox) on another attempt. As a last crazy attempt, I had the Select statement doing a .PerformClick on btnTest (which works if I navigate to the page manually).
The only way I found to set the focus on a TextBox inside a TabPage is:
Private Sub Form1_Shown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shown
TextBox1.Focus()
End Sub
How do I code in vb.net that the text box can only accept 10 inputs from the user. User can only enter 10 strings.

On the KeyDown event of the textbox, i need to capture the character pressed and send it to a function which fires a sql query for this character.To get the character i am using Convert.ToChar(e.keycode).However Convert.Tochar converts the keycode to char according to its ASCII value , thus F4 gets converted to "s" as "s" has ASCII keycode of 115.Is there some other way to convert the keycode to character which won't make these wrong conversions as even if i restrict the functions keys there may be problem with other key conversion also.

View 3 RepliesI created a function that retrieves information on which checkboxes are checked. It returns an array which the information coupled to the checking of those checkboxes.

I have a validating event for a txtbox called txtname. If the user tries to leave txtname for another txt box without entering their name a messagebox comes up giving an error. I have an exit button which will when clicked ask you if you really want to leave then you can choose yes or no. I can't seem to figure out how to allow the user to click the exit button while leaving the txtname blank so it would bypass the error message and only bring up the exit prompt. Here's what I have coded for the validating event and the exit event.

What's the difference between the SizeChanged event and the Resize event?
View 4 RepliesFollowing on from my post yesterday (how to anchor buttons/controls to various sides of the current form when the form is resized) I have run into another problem. I am setting the width of my datagrid to be 80% of the form width on a 'form resize' event with 10% of the width at either side so it remains centred in whatever size window is available. This works fine. (mydatagrid.width = me.width/5*4)
I then decided to dynamically set the width of the 2 columns in the datagrid each to 50% of the width of the datagrid. Again, this sub is called in the 'form resize' event. This fails because the datagrid hasn't loaded the data from my sql database when the first 'resize' event is triggered. I did a bit of testing (by placing a simple msgbox statement into the resize event and the load event) and it seems the 'resize' event is triggered three times before the form's load event.
how do I stop the resize event triggering when the form loads (or at least make the load event trigger first).
OK, so my project is like this:The user selects a folder from their computer that holds a list of subfolders.

Here is the code that adds the checkboxes:
Dim iCol As Integer = 1
Dim objFolder As Object = Nothing
For j = 0 To rCount - 1 '0 to dynamic number of rows
