A string question

Can any body tell me how I would trim ‘TestAirplane’ out of the string below?

C:\Targets\TestAirplane\TestAirplane_WebDoc\TestAirplane_HDS\01 Fuse

The only constants are the slashes “\” and the word “Targets”

I know that I want to find “Targets\” and trim it and everything to the left and then find the next slash”\” and trim it and everything to the right...just can’t figure out how to do it.

Thanks
Brad

You could use the String.Split command, but thats only if you know for sure that the desired String in the returned array is the 2nd last element.

Dim path as String = "C:\Targets\TestAirplane\TestAirplane_WebDoc\TestAirplane_HDS\01 Fuse"<br />
<br />
Dim s as String()<br />
<br />
s = path.Split(chr(92))<br />
<br />
return s(s.Length-2)

OR

if you place in a FileInfo object you can call the FileInfo.Directory.Parent method which will return the local directory of where the file is located.

Dim f as new FileInfo("C:\Targets\TestAirplane\TestAirplane_WebDoc\TestAirplane_HDS\01 Fuse")<br />
<br />
'should return TestAirplane_HDS<br />
return f.Directory.Parent.ToString

That works good but I don't understand what (chr(92)) is doing. Specifically, what is the 92 for?

Thanks

Thats the ASCII key code for \
For more info at those key codes, you can check ASCII Character Codes[^].

BTW, if you want to be really fancy, you can use the IO.Path.DirectorySeparatorChar instead... Wink | ;)

Hope this could help you! Cool | :cool:

I'd suggest that chr(92) is a complete hack. I certainly wouldn't use it.

With the \ in quotes. \ is used to escape things, so you probably need to do Split('\\') instead of Split('\').

Oh ok, is that also in VB? I thought that escaping with \ was only in C, C++ and C#.
I never had any problems with it...

I dunno, but I can't imagine why else someone would use chr(92) or whatever it was.

How do you put a control character in a string in VB then ?

Well, i think that is the only flaw in VB Wink | ;)

Instead of "Blablabla\nSome more bla", you have to do "Blablabla" & vbNewLine & "Some more bla"
Also, \t = vbTab, \" = "" and \x92 = Chr(92)
A lot more typing... Frown | :(

Cheers!

i cant remember if \ is a control character in VB but certaintly in VB6 i used to use the chr(92) format quite a lot. For one project i needed to build a VBScript string containing SQL and i found using the character ref was pretty much the only way when creating a string with ' " combinations. Dont think its as much of a problem in VB.Net but i havent really tried.

Split is probably the easiest way to do this, as has been said, but a regular expression could also be used if you wanted to.

Not sure exactly what you are after; here are several possibilities:
Where s = "C:\Targets\TestAirplane\TestAirplane_WebDoc\TestAirplane_HDS\01 Fuse"

s.Substring(0, s.IndexOf("Targets\") + 8)
Returns "C:\Targets\"

s.Substring(s.IndexOf("Targets\") + 8, s.Length - s.IndexOf("Targets\") - 8)
Returns "TestAirplane\TestAirplane_WebDoc\TestAirplane_HDS\01 Fuse"

s.Substring(s.IndexOf("Targets\") + 8, s.IndexOf("\"c, s.IndexOf("Targets\") + 8) - s.IndexOf("Targets\") - 8)
Returns "TestAirplane"

Is there a way to get the selectedvalue (or selectedtext or selecteditem) from a databound combobox into a string variable? I keep getting cast from datarowview to type string not valid.

Give one of these a try:

ComboBox.SelectedValue.ToString

OR

ComboBox.SelectedItem.ToString

The error is in result of a query

'field_names is a string
'field_number is the underlying value

commandtext = "Select field_number,field_names From field_info where field_number = " & cbfieldEdit6.SelectedValue.ToString

cbfieldedit6.text works, but I need the underlying value

I think I will have to do it in a round about way...

commandtext = "Select field_number,field_names From field_info where field_names = " & cbfieldEdit6.text

and then use a datareader to get the value I need.

field1 = dr.getvalue(0)

oops... modified query

commandtext = "Select field_number,field_names From field_info where field_names = '" & cbfieldEdit6.text & "'"

This person ran into a similar problem when casting to an Integer. Perhaps this is your problem?
