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.

Is it possible to convert string mycolor to Color variable as defined before?
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:

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.

I know that in WPF, FontSize = 1/96 of an inch (same as 1 pixel I think). Is the FontSize dimension the height, the width, or diagonal size of a character? I would guess it's the font height, but the Microsoft documentation doesn't really indicate what it is.
Also, is there an easy way to get the height and width of a font size?So it looks like the FontSize is the height, and the width can only be determined (without knowing the actual character) on monospaced fonts since proportional fonts have varying widths.
I've been trying to look for answers on how to do this, for days, but just couldn't find one. Maybe I don't know the keywords to look for. I hope someone can help me with this. Here's my problem. I'm trying to create a wordpad and I have two ComboBoxes (FontName & FontSize) and a RichTextBox. I'm trying to figure out how to get the FontName and FontSize of a SelectedText in the RichTextBox and be selected automatically in each ComboBoxes?
View 2 RepliesCan't seem to find a way to make the text appearing in Msgboxs to be enlarged.
Tooltips appear to be the same font.
I can't set the FontSize of the Text in a TextBlock, since the TextBox is in a Viewbox. Why?

I can set the FontSizes of all of the TextBlocks but not of the TextBlock which is in the Viewbox.
I have a single that might have a decimal place but might not. I have to put the digit before the decimal into the first 4 bytes and the digit after in the next 4 bytes.
So 1.1 would be 01-00-00-00-01-00-00-00
or 2.1 would be 02-00-00-00-01-00-00-00
or 1 would be 01-00-00-00-00-00-00-00
The digit before the decimal point is stored like an integer in bytes the same with the digit after the point. So 1.1 gets split into 1 and 1 and then stored as 2 DWORDS: 01000000 and 01000000
Follow-Up available: There's a follow-up with further details, see Convert MBF to IEEE.
I've got some legacy data which is still in use, reading the binary files is not the problem, the number format is. All floating point numbers are saved in MBF format (Single and Double). I've found a topic about that on the MSDN boards but that one only deals with Single values. I'd also would like to stay away from API-Calls as far as I can.
Edit: Just in case somebody needs it, here is the VB.NET Code (it's Option Strict compliant) I ended up with (feel free to convert it to C# and edit it in):
''' <summary>Converts a MBF Single to an IEEE Single</summary>
''' <param name="src">The MBF Single value</param>
''' <returns>The converted IEEE Single value</returns>

I have working code that will convert an xls to pdf, however, the code converts the whole workbook and I really just need to select a single sheet out of the workbook, but I can't figure out how to do it.The code I currently use is:
Dim fileName As String = "filepathfilename"
Dim xlsApp = New Microsoft.Office.Interop.Excel.Application
xlsApp.ScreenUpdating = False
[code]....
Where in the code do I need to specify the sheet in the workbook? Note that I will need to make it so that depending on an option fed into the app, the sheet will change, though I don't think that should make a difference, but I thought I'd mention it either way.

I have a vbscript which I would like to compile into a single .EXE file. It's my understanding that you can't do this with vbscript and that the available applications which supposedly do the conversion are actually just glorified self extracting zip files which dump the vbs to a temp folder and run the script - not what I want.I've no experience in VB.Net and very little in VBS so I'd appreciate it someone could look over the script and let me know what areas I need to change so I can investigate the correct syntax in VB.Net.what the script does just in case there might be an issue from the conversion. The script does several things in this order:starts by scanning a CSV file (which contains a list of peoples usernames, their department and full name) looking for the line that contains a username match to that of logged in users's logon name via expanding the environment variable %USERNAME%..Once found, it splits the entire row into an array..Sets a series of Environment variables at Process level using contents of the array as values..Does a basic time check and sets the result as environment variable as above..Checks to see which version of CAD application is installed on users machine and starts application with command switch to process configuration file during startup..I don't think its overly complex now that I understand the VBS code but in VB.Net, I don't know what lines will work and what won't. I've not installed Visual Studio Express yet but will do so shortly - I presume this program is suitable for converting my script? [code]

View 1 RepliesI have a function in VB.NET that runs a query from an MS SQL DB, puts the results into temporary variables, then updates an Oracle DB. My question is, if the string in the MS SQL contains a single quote ( ' ), how do I update the Oracle DB for something that has that single quote?

I am struggling a bit with a string conversion. My platform is VB in Visual Studio 2010, windows form application. What I have is a Single float that occupies four characters of a string. Where Chr(0) is the LSB of the single and Chr(3) is the MSB of the single. This string is loaded by a built in function that communicates to an external microcontroller via tcp/ip that I do not wish to modify. I am having trouble figuring out a way to get these chars from a string to a single data type. I dont need to convert the data, just move it. But I keep getting type errors and not sure how to handle it in VB.

I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.
