.net - Select Something And Change The Text Of A TextBox -- #name? Error
Oct 21, 2010
For some sort of reason, which I can't seem to spot, this fails and I get a #Name? error. When I tried to do this, I use pretty much the same code in another place in my form; the only difference is the "cbo" and the names of my txt and alike.
[code]...
Can anyone spot my error? What I wish the code would do is when I Select something in my cboVarenummer, the TextBox txtVarenavn changes its text to what the sql statement returns.
while I am inserting the data through textbox of the selected item of the list box I want the when the user will input the data into textbox and then pressing the insert button the the selected item of list box (selected item only color change) color change white into blue or red.
I am building a vb.net application for a company. In my application, I have a form which has many textboxes. When user set focus on them, all the text in is selected. My problem is I don't want to write a code for each textbox because there many of them.
I'm using the code below to select the text within my textbox during the mousedown event. It works great when the HeaderChanged sub is not called. The problem is, the HeaderChanged sub will always be called on the textbox's focus event.If the user clicks the far right portion of the textbox the whole text value will be selected (like it should), but if the user clicks near the left side of the textbox only a portion of the text will be selected.
I cant seem to find any link or topic regarding my problem. I have 2 forms in a project, form one has labels and adjacent combobox while the other form (form 2)has textboxes with adjacent combobox. I am supposed to change the text property of the labels using textbox entry from form 2 and add/delete/change combobox contents in fom 1 using entries combobox at form 2.

For some reason i can't select text with the mouse in my application.Also my clients experience the same behaviour.I know it was possible to select a part of the textbox and it stayd selected. Now the selection dissappears and the cursor moves to the front.Only a doubleclick functions properly but selects a single word only.
I am using Visual Basic 2008 I am trying to capitalize words in a text box. I am using the following code (which, in case you don't recognize it, came from an example which I modified):
Public Sub FuncKeysModule(ByVal value As Keys) 'Check what function key is in a pressed state, and then perform the corresponding action. Select Case value
[code]....
In the application, I select a word in the textbox then hit F2. The text is pulled from the textbox, I manage to change the first letter to a capital letter BUT I cannot change the textbox.I already set the ReadOnly property of the textbox to False when I initialized the textbox. It looks like the Replace function does not work.
I am trying to bind a textbox to a binding source (using the IDE DataBindings Editor) and it works fine except for one thing: if I delete the text I get the subject error. What I want to happen is the datarecord field be updated to a dbnull value -- how do I get that to happen?
I am having a problem changing the text color of a textbox in vb I know that changing is like this

I have a read-only textbox named txtStartDate in which when the user clicks, a calendarextender will appear and the user can select a date.
Now I have another textbox, txtEndDate, which should automatically change whent the user changes the value in txtStartDate.
But the problem is, the TextChanged event will not work since no postback will occur. When I tried to set the autopostback property to true, I receive a jquery error so I decided no to go with it.
I am using this in my popup usercontrol. Is there a way in which I can trigger a postback so that I can get to change my txtEndDate when the value in txtStartDate changes or when the user clicks on the calendarextender?
I have Microsoft Visual Studio 2010 (not sure on the differences of each version) Ive googled and looked all over. I dont like asking people to code everything out for me, but ive spent too many hours trying to figure out how to solve something that seems so simple.

I'm building a small program and I have a numbers only textbox where its content need to be higher than 1. So what I have is a messagebox pop when the text change and its lower or equal to 0. What I'd like to do is have the text changed to what it was before the number was changed to <= 0.Here's what I have for the control:
Private Sub txtDelay_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtDelay.TextChanged If txtDelay.Text <= "0" Then MessageBox.Show("Delay must be atleast 1 millisecond.", "Delay Error") End If End Sub
I got a Sub which processes a code, and then it does whatever the code said. Example.
Code = "Black" -> Turns screen black. Code = "OFF" -> Turns off the PC. And so on.
If I call that Sub from Immediate console, It works perfectly. But if that Sub is called from an event, It does nothing, and usually throws an Exception. I read somewhere that I can fix this by using Threads, but I don't understand how that can help and make it work.
We have some code in the textCahanged event of a textbox. We only want to fire that code if the user types into the box, not if we change the text in the box programmatically. Can I detect what caused the text to change?
I have two drop down. SelCurrentManuf and selCurrentModel. I want the option in selCurrentModel to change depending on the option selected in selCurrentManuf. How do i do it?
This is how i am currently populating selCurrentModel
Public Sub PopulateCurrentModel() Dim mySelectQuery As String = "SELECT * FROM Model where ManufID = "+ selCurrentManuf.Text+";" Dim myConnection As New MySqlConnection(Session("localConn"))
[Code]...
but it only populates the first selected manuf, and doesnt change after
Private Sub selCurrentManuf_SelectedIndexChanged(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles selCurrentManuf.SelectedIndexChanged PopulateCurrentModel() End Sub
