.Net 2005 Ghost Text Box - Unable To Get It Working All The Time?
Feb 22, 2010
I've been trying to make up a Ghost Text Box, so that it shows some 'ghost' text when its contains nothing.
What i did was inherit from the normal textbox, and use OnPaint to show the ghost text, the User paint is switch on/off depending on if there is any text in the textbox.If i start (in the design) and add some text it all works as i expect at runtime, but the text does not get shown at design time (for some reason)
If i clear the text at design time, then it shows the ghosted text at design tim. At runtime the ghosted text is shown, but when you click in the box and hit a key, the key is shown in bold, which is odd as the font is not in bold.

I tried to create a ghost text using Labels over the Textboxes. I am using VB.Net2005. I accomplished this with this code:
Public Class frmDataEntry
Private Sub PhantomTextLastName()
If txtLastName.Text = "" Then
[Code].....
Is there any way to reduce this code, so that when I try to add another Textboxes I'll never have to retype a bunch of codes. I have basic knowledge n using Module and Class

I want to be able to type text in a search box (textbox1) and have the datagrid adjust at the same time. My datagridview is called DGEstudent and the data source is dataset2 and is pulling from the student table. As soon as I start typing in the textbox my datagrid just goes blank. Private Sub TextBox1_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.KeyUp
Dim dv As DataView = New DataView()
dv.Table = DataSet2.Student
dv.RowFilter = "First_Name like '" & TextBox1.Text & "%'"
DGEstudent.DataSource = dv

I have 5 errors that come up every time I run my project They are all "A first chance exception of type 'System.ArgumentException' occurred in System.Drawing.dll"
I have try catch blocks around every piece of code I have written, and it does not seem to catch them, so I opted to catch the appdomain.UnHandledException.
That does not seem to catch them either If I step through the code line by line (several hundred lines so I hold down f8) it does not make the error...
Only when I run full speed.
I can only figure that I am accessing something maybe before an object is completely drawn, however how in the heck would anyone suggest I go about finding it, and why will my global event handler not catch them?

I would like to be able to time a page load time in ASP.net (VBscript). Adding Trace="true" to the page directive is nice, but I need to actually time an event and store it in a variable.In ASP it was easy with the Timer object, but in .net I can't find anything on Google.

I recently moved my Application that was running off of Window XP and created in VS 2005 over to a box that's running Windows7.Now, when I try to debug, I can't edit. In the lower portion of the screen, it gives me this error: Cannot currently modify this text in the editor. It is read only.
Under Tools->Options->Debugging, Edit and Continue are already selected; so it's something else. Also, under project properties->compile I have it set to Cofiguration (Active Debug) and Platform (Active Any CPU).

I am reading a CSV file using OLEDB command in VB.Net
Everything is working fine. the only problem is that one of my columns has time value in a format "07:53.8"
When i read this value using dr.item(1), it reads the string into a date "01/25/2012".It gives me the same value in dr.item(0)
I am not able to read the correct value as shown in the CSV file.
following is the code
For I As Integer = 0 To 2
dr = dt.Rows(I)
MsgBox(dr.item(0))

Quote:
lblTotal.Text = Val(Form2.lblPizzaTotal.Text) + Val(Form3.lblDrinksTotal.Text)
The code above is what I am using to add the Value of Label 1 (Pizza Total) and Label 2 (Drinks Total), however it seems that in the final total it doesn't appear to add the value of Label 2.

I've got my program to run a set of code based between certain variables. The variables are:
RBM (Radiobutton for male gender)
RBF (Radiobutton for female gender)
Based on that, it runs a new sub which then does a select case based on ClassBox (Listbox) index.
Now here is what I don't get. When I run the code, it works flawlessly except on ONE of the case selects.
Here is what I've got for the codes:
[Code]...
If I select anything, it loads the correct directory. The error isn't the case selects, I put them in there in case I missed something. I ran debugger with breakpoints so I could see if the data was getting crossed wrong. When I select index 4 on the female sub it loads the correct directory and I set a breakpoint for "OFD1.InitialDirectory = Race" which Race showed the correct directory, but when the OFD1 came up, it's not the folder 91 (Index 4 in female), it goes to 80 (Index 7 in male) which isn't even a female option and it's not the same index in the male section either.

Just getting started in VB.NET. I would like to add X-number of text boxes at run time. And then be able to address them by their index or some sequential numerical value (like an array)
This is what I have so far:

When I turn this into a loop to create multiple toolboxes, how do I assign a name to the controls, or will all of them be named "MyTextBox" ? I'll increment their position so thats no problem.

I have a form from which I am visually representing data (from access database). I have set up a user log on a separate form (allows user to make comments as they scroll through the data and see any points of interest etc). The second form is linked via a textbox in terms of a common field in this case the field name is "Datetime".
What I want to do is be able to scroll through the data and make notes on the second form and add them to another table in the database. I have managed to do all the above but obviously loose focus of the second form when i scroll through the data on the first. Is there any way of being able to interact with both forms at the same time?
