View 6 RepliesForms :: DateTimePicker - Setting Minimum And Maximum Value
Dec 4, 2011I have a list box on my form with 2 value - "2010" & "2011". When I change the value in the listbox it should set the minimum and maximum value of 2 datetimepickers. Each time I try to change the value I get an error - for example if I change the listbox from 2011 to 2010 I get the error:
"Value of '31/03/2011 00:00:00' is not valid for 'MaxDate'. 'MaxDate' must be greater than or equal to MinDate. Parameter name: MaxDate"
If ListBox1.SelectedIndex = "0" Then
DateTimePicker1.MaxDate = #3/31/2011#
DateTimePicker1.MinDate = #4/1/2010#
DateTimePicker2.MaxDate = #3/31/2011#
DateTimePicker2.MinDate = #4/1/2010#
End If
If ListBox1.SelectedIndex = "1" Then
DateTimePicker1.MaxDate = #3/31/2012#
DateTimePicker1.MinDate = #4/1/2011#
DateTimePicker2.MaxDate = #3/31/2012#
DateTimePicker2.MinDate = #4/1/2011#
End If
Limit The User Input To Exactly 5 Characters?
Mar 11, 2011I have 200 dynamic textboxes.
I am trying to limit the user input to exactly 5 characters ( not more, not less ), and numeric only.
I have been trying this :
Private Function txtValid()
Dim str As String
For Each txt As TextBox In Panel1.Controls
[Code]....
But it always shows the last messagebox. Not all 200 textboxes will be filled in, so I suspect that it may have something to do with that, but I just need to stop the user from entering alphabetical characters, and the entered field must have a length of 5

View 2 RepliesForms :: Maximum Row Number In Multiline Textbox
Apr 21, 2010i am trying to put a maximum row number of lines in a multiline textbox. What i want is to achieve something like a console, with a maximum number of rows, with the top rows to dissappear and to keep always the last i.e. 500 rows. a note: for the textbox text i use the following algorithm
dim text
textbox.text = textbox.text & vbcrlf & text
the problem is that after a certain number of rows the program starts to get a little slow. So i guess if i put a limit to the rows i will fix this.

Forms :: Setting A Value To A Textbox In Another Form?
May 5, 2010I'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?

View 3 RepliesForms :: Setting Value Of A Textbox In A Webbrowser Control?
Sep 20, 2011I 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).

I believe I need a function to make this happen.
Asp.net - Setting Minimum And Maximum Date On Calendar?
Apr 19, 2012I've had a look around, once again and can't find how to set the minimum and maximum dates allowed to be selected on a calendar in ASP.net with VB.
I'm using Visual Studio 2010 and it's just a regular Calendar control at the moment...

Forms :: Resize Event - Setting Button In Textbox?
Apr 30, 2009So 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?
