Is it possible to convert a string into a control?
Dim Ctrl as string = "DataGridView"
Dim Index as integer = "1"
Dim g as DataGridView = DirectCast(Ctrl & Index, DataGridView)
and then access the properties of the Grid...
g.BackColor = Color.Red
g.Left = 3
etc.
I'm pretty sure it's possible but nothing I've tried works.

I have written a C++ code to modify a string, the code is:

I'm supposed to convert the string in one textbox to binary, and display it as binary, in another textbox. I can make this part work, but when I want to convert it from binary and back to text, it all goes bananas.Here's the code I'm using for the conversion:
Private Sub Button1_Click(ByVal sender As System.Object,
ByVal e As System.EventArgs
) Handles Button1.Click

I'm trying to convert an integer (0 to 255) into a 2-value hex string. For instance, if the integer was 255, the hex string would be "ff", if the integer was 15, the hex string would be "0f". The issue I'm having is trying to keep the leading 0. I've been able to overcome this by using an if statement to determine if the length is less than 2, in which I would concatenate a 0, but this is pretty inefficient I think. Here's my
Dim get_integer as Integer = TextBox1.Text Dim hex_value As String = Convert.ToString(get_integer, 16)
If hex_value.Length < 2 Then
hex_value = String.Concat(0, hex_value)
End If
how to improve this? I really would like to get away from using the if statement.
could anybody point me in the right direction in regards to the following problem? I have some data that has time and date in form of ordinary string. The format is always the same, for instance:

How can I convert it to time understood by computer and check if given time is in the past of in the future in comparsion to current time on my computer? I would also like to be able to tell how much difference there is between the time from my data file and the current time. For instance to say "this time was 3 hours and 20 mintues ago".
I have a combobox which I want to use to change the font-size of text, but I'm getting an error.
vb.net Dim xfont As New Font(font_cbo.Text, font_cbo_size.Text, FontStyle.Regular, GraphicsUnit.Point)
Conversion to Type Single is invalid So I tried to convert the string to Single, but with the same error. If I replace the "font_cbo_size.Text" to a number, it'll work fine.
Lets say I have a combo box that contains the values "alpha", "bravo", "charlie", etc.
When the user selects a value from the combo box, then that value will be written to a string variable, like...
Dim ComboSelection As String = combobox1.SelectedValue
Now, lets say I have a bunch of panels on my form, which have names corresponding to each combo box value. For example...
pnl_alpha
pnl_bravo
pnl_charlie
etc etc.
So what I would like to do is use the value of ComboSelection to access the appropriate panel (instead of using conditional statements or select case statements).
For example, whichever value the user selects from the combo box, I want to change the corresponding panel's background color to blue. So in the combo box's click event, I want to do something like this...
Dim ComboSelection As String = combobox1.SelectedValue
Dim PanelName As String = "pnl_" & ComboSelection
PanelName.BackColor = Color.Blue
Is it possible to do something like this? Again, I realize that I could easily use conditional statements to accomplish this task, but I am curious if it is possible to do it this way instead, as I would have many uses for this functionality.
I'm looking to put a few labels on a form but the text that they will display will not be static. Instead they should be dynamic as the values used will be either the value of a specific Environment variable or from a value stored in an array. These values will change depending on which user runs the application. How do I achieve this?
View 2 RepliesI'm writing a custom control and I want to add a "MessageText" property of type String:
<Browsable(True),
DefaultValue(""),
Category("CustomControls"),
[code]....
The MessageText property is a multiline text, and the user must be able to set the text using the designer. The problem is that the designer doesn't allow to enter a newline directly for a string property.I want the same behaviour as the system TextBox's Text property, where you can click on the down arrow and write lines in the small text-editor that appears:How do I do that?
I'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:
dec2bin
dec2oct
dec2hex
bin2dec
oct2dec
hex2dec
I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.

I'm working on a mass text replacer program because I'm sick of all the 10-day trial ones out there that aren't very good.The entire program is basically finished (All easy stuff), but now I need to code the actual replace/delete stuff, which I'm stuck on because apparently the way I originally intended to do it is not possible.
The way it works is you load a text file (.txt, .cfg, .ini, .doc, etc.) which opens a StreamReader which writes all the data into a listbox. Then you pick whether you want to replace or delete a string. If you select replace, then you enter the string to search for and in another textbox you enter the string to replace it with.
The way I originally intended to do this was like this:
If o1.Text = "Replace" Then 'The option
Replace(txtfile, str1, a1) 'txtfile is the data, str1 is the string to find and a1 is the replacement
End If
The problem is, I believe this method requires txtfile, str1 and a1 to be strings, but they're all 1-dimensional string arrays, which cannot be converted to strings, or at least I don't know how to convert them.
A friend told me one way I could do this is to open both a StreamReader and StreamWriter and do the replace/delete line by line as they are entered into the memory and write them to a temporary file which is then copied over the original. I can do this kind of, but I still don't know the proper way of doing the actual replace code because the string to find and the string to replace with are still 1-dimensional string arrays rather than strings.

Value of type 'System.Func(Of String, String)' cannot be converted to 'System.Converter(Of String, String)
