in An MDI form , i make a childform with textboxes. these textboxes are produced by the code, like this:
For i As Integer = 0 To number Step 1
Dim TextBox As New TextBox
ChildForm.Controls.Add(TextBox)
[Code]....
In another sub within the MDI class i want to read the data from the textboxes, but got an error that says txtBox1 is not a member of 'WindowsApplication1.Form1'.This is true because they do not exist yet. How can i handle this? I think it has something to do with "delegate and invoke", but this seems to be hard to understand.
Is there any way of making controls that aren't textboxes into readonly controls? Specifically I have a date time picker (but I have the problem occasionally with other controls), that I want to make ReadOnly as opposed to disabled so that the user can see clearly what is in the control but cannot edit it. Making a control like this disabled makes it hard to read and furthermore, gives the impression to the user that they are to ignore the field, which defeats the object.
I'm sure a suggestion will also be to stick the information into a text box, however there are other date time picker controls that CAN be edited in the same window, and it would make life a lot easier if the layout of each was exactly the same.
This works if I don't have an IfElse statement but even then it only shows 1 txtBox().I want 4 panels and 4 rows of textboxes in each one. with multiple txtbox()'s in each oneI'm just starting on it, but as usual I hit an error, see below. Also, how do I get this code in here without the double spacing problem?
Dim pnlbox(4)
As Panel
Dim txtBox(70)

View 4 RepliesMy goal is to take some form inputs and prompt the user to download a summary of everything once a certain button is clicked. I have no need for the file once it is downloaded and so I'd like to have a solution where the data is streamed directly to the user. My current solution doesn't even prompt the user for a download. Can anyone point out what I'm doing wrong?[code]....

I was looking for some better way of coding to populate all text boxes and make them visible once a button is clicked. I have a letter like format on a page with labels displaying address, name etc and it was recommended that on this page some of the information should be able to be edited. The idea I had was to keep the labels displaying the information but then when the edit details button is clicked the labels disappear, text boxes will appear and be populated with the same text as the label to allow the user to edit the details.
I seem to repeating lines of code but changing one thing each time on page load
Dim Sname As String = Request.QueryString("Name")
lblStuName.Text = Sname
tbStuName.Text = Sname
tbStuName.visible=false
[Code] .....
On edit button
tbStuName.visible=true
tbAddress.visible = true
etc..
On the save button
sqlStatement = "UPDATE StuTable SET Name = '" & lblStuName.Text & "', Address = '" & lblAddress.Text
My code seems very repetitive in many parts, I was looking for a better coding style to do this.
i have 3 textboxes on an asp.net page and i would like to send the text on all those textboxes as an email message body when a button is clicked. I want each text on each textbox to appear on a new line(this i can do), but i also want the lines to be bulleted.
Something like
Text on Textbox1
Text on Textbox2
Text on Textbox3

I am programming in VB 2010 and have a question. I have some code that currently only applies to one text box. As you will see, I have sub setup to handle multiple textbox events. My question being, Is there a way to take this code and apply it to all textboxes that are being handled?
VBCode:
Private Sub TextBoxes_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles fnameTxBx.TextChanged, _
lnameTxBx.TextChanged, streetTxBx.TextChanged, cityTxBx.TextChanged
Dim theText As String = fnameTxBx.Text

I'm trying to make a Doctor's program where the doctor has to enter the patients detail into several text boxes (Name, Age, Address...). So, after he has entered all the information, he would want to save it somehow so he could open up the information
again. How would i do that. I thought it could be saved in a database, or even in a text file.
I have a datagrid where the first column is for image button for expand purpose. The visibility of the image depends on some conditions row by row. I am trying to handle this in ItemDataBound event, and using e.item.cell(0).findcontrol("imageButton").visible = false. The first cell of this row therefore disappears even that the size is specified in the ItemStyle tag.
View 3 Repliesthere are two forms, form1 and form2. form1 has textboxes 10, the user can enter data in a specific number of textboxes: ie: 5 or 3, or etc.
then the user clicks a button, and based on the number of textboxes that he entered data on, form2 will load a number of texboxes: If the user filled 3 textboxes in form1, form2 will show 3 textboxes.
I need to have it so a user can select two numbers from some listboxes and then have those two numbered form's values switched.[code]...
