See subject of positing for question.
1) I recall seeing a really cool option in VB.NET using LINQ to match using "LIKE%'
2) I know regular expressions will work and I suspect that will result in the shortest code and probably won't be too hard to read for such a simple test.
Here's what I did.
Private Shared Function FileNameIsOk(ByVal fileName As String) As Boolean
For Position As Integer = 0 To fileName.Length - 1
Dim Character As String = fileName.Substring(Position, 1).ToUpper
Dim AsciiCharacter As Integer = Asc(Character)
Select Case True

Quick query...I'm trying to scan a long string and return any values that occur between the tags <FileName> and </FileName> I've got a bit of code here to use regular expressions to return the position of the occurunces of both substrings..Just wanted to find out if there is any way to scan for both substrings within one loop (as im currently doing 2, one for the first substring and one for the 2nd) so I can use something along these lines:
ringlist = Mid(XMLRESP, (startloc + 1), (endloc - 1))
MsgBox(ringlist)
to msg box the value between the substrings...either that or another approach to return the value between the 2 substrings (it can be of variable length)
Dim patternstart As String = "<FileName>"
Dim patternend As String = "</FileName>"
Dim matchesstart As MatchCollection = Regex.Matches(XMLRESP, patternstart)

In VB.net I've got the following line that removes all non-alphanumeric chars from a string:
return Regex.Replace(build, "[W]", "")
I now need to extend this to remove non-alphanumeric chars that aren't [] or _. I've changed the line to:
return Regex.Replace(build, "[W[]_]", "")
However I'm pretty sure that this says
replace non-word or [ or ] or _
how do I negate the tests for the [] and _ chars so that it says
replace non-word and not [ and not ] and not _
Some examples:
"[Foo Bar_123456]" => "[FooBar_123456]"
"[Foo Bar_123-456*]" => "[FooBar_123456]"

The issue is in the last line. ID_Part is an Int64 data type filters(0) is a string so the system returns a "Can't perform 'Like' operation on System.Int64 and System.String" error message.As you can see I tried converting the data type, but that failed since it is encased in String.Format()- it's going to be a string no matter what, I suppose.It's almost 1:00 a.m. so I'm not firing on all cylinders.
How would I do that? Sample code is below that demonstrated that the file I opened contained the full path and file name.
I want to extract just the path and serialize that to the user.config file as a UserSetting value. Then next time the user opens the dialog box, it uses that saved path string to go immediately to the location previously used.

I have a Listview on my form with different files. I can selet a file en open it with the proces start method. To open the file i use the OpenFileDialog method and select the filename. This work very good. With the code below.
My question is if there is a method to get the selected file without using the OpenFileDialog Box. So when i dubbelclick the selected file the proces will start with open the selected file. Something like:
proc.StartInfo.FileName = Me.SelectedCell.FileName
instead of proc.StartInfo.FileName = Me.OpenFileDialog1.FileName
PS) May be i can preduce the Filename using the OpenFileDialog method on the background.

View 2 RepliesI have an application that has a list of string that needs to be search in a database table field to select rows with the same name and retrive the values of one particular fields that contains the file name with extention for that string. With this new generated text file, I pass the filename with the extension and search the folders that are listed in a txt file. All of this works fine.
Now I need a more simple version of this application, without using the database to get the filename with extension. Instead, read the text file with input strings, search in the folders listed in another text file(to know the location of the folders to search for the string). If any file that matches with the string in the text file, I need to copy those files to another folder.

is there any way to attach a sql mdf by filename but actually make the database name something else?
the problem i'm having is that my connection string attaches the database just fine, but it gives the database a name of it's full path on the hard drive when i pull it up in SSMSE. ie. "c:program filesmy programmy database.mdf" is shown as the name when i do a sqlcmd and issue a select name from sys.databases
the snag is being hit due to the fact that i'm trying to do a "bcp in" and because a: there are spaces in the database name, and b: there's the .mdf extension also added to the database name that when i run my bcp in command it errors out, even if i use the -q option of bcp.
if i start SSMSE and right click the database and rename it, bcp works great - so my question is, how do i correctly format my connection string to attach to c:program filesmy programmy database.mdf, yet have it attach the database as "mydatabase" for use in bcp statements?
i've been to connectionstrings.com and they only cover the standard connection strings
in summary - i want to attach an mdf file programmatically and specify the name that ssmse see's it as....

I'm stuck at making an vacationplanner. For example: an employee can request a day off which request is send to an access database. After which the request has to be approved (or declined) by a supervisor. The supervisor logs in and goes to a overview form to see outstanding and approved request. I use a Datagridview to display the name of the employees at the Y-axis and the corresponding days in the selected month in the X-axis. Then I loop through the access database to fill the specific cells with an grey image on specific days for part-time employees.
After this I loop through a seperate accessdatabase to retrieve the outstanding and approved requests and fill the corresponding cells with an image. Example: yellow image for outstanding and green for approved requests.
dgvBezetting.Item(dag, rij).Value = Image.FromFile(Application.StartupPath() & "/uren/grijs.jpg")
Now I get to the part where I'm kind of stuck.
In the mentioned datagridview the supervisor can see the already approved requests. But, when an employee suddenly changed or canceled the already approved day off, the supervisor must be able to delete the request. I can find out with hitTest on which cell the supervisor has clicked and from there check the database for request entries, but this will consume a lot of database transaction when the supervisor keeps clicking on cells witch no data in it.
What I preferably want.....
I actually want to check if the clicked cell contains an image or not and from there on continue with an connetion to the database or not. But, I can't figure out how to retrieve the imagename or if there is an image used or not... I only get the result 'System.Drawing.Image', 'System.Drawing.Bitmap' or 'Image', nothing referencing to the imagefilename..
