My card program generates a text file AllCards.txt - I want to know when the first character in this file is identical to the 3rd, 5th, 7th, or 9th. In this case I would need A (1st char) checked against the 5 (3rd char), 5 (5th char), 7 (7th char) and 8 (9th char).

I want define where my application and user settings files will be located.I would also like to rename them.For example my project will have a number of folders located inside the application folder when deployed.One of those folders is labelled "Cfg" and i want my application settings files to be saved in there.This is including the user settings, i dont want to localize the user settings file as is done automatically (at least not at this stage).
View 3 RepliesI have a generic question regarding file paths and user interfaces. I am trying to build a user-interface to accommodate various file locations. I typically build interfaces which deal with files on drives. As such, I use a directory tree for this. I usually work with files on local drives. However if I wanted to ensure that all file locations were dealt with I would want to ensure that I was accommodating files in all drives (local, network, mappped etc.). I am assuming that the treeview would support all of these drive option.
However if the files are on a sharepoint site or in some other type of enterprise content system, then am I correct to assume that these file paths will be URLs? If so, then am I correct to assume that a directory tree is not the correct control to use for these locations? Should I be providing a textbox to the user and prompting them to enter this URL? Or is it better to have the URL loaded into a ListView or ListBox (i.e. "My Connections") and then provide these as options via a dropdown box. I am trying to picture a typical user interface. Is it a directory tree AND a text box/dropdown box.
As things are now, I need my program to store x number of file locations. My first approach was to use an array, however as i do now know how many files there will be, i am forced to use redim preserve. That is not very effective and I have therefore started using a StringCollection.
or is there some smart way to store these paths, that I have overlooked?
I am doing setup project in VS 2008. I used custom action to select file from local drives. On the button click of custom action form, I am launching Open file dialog as ofdGetNetPath.ShowDialog When I run the setup on Vista, and click the button to open the openFileDialog, it hanged, form becomes non responsive and I have to cancel the setup.
on debugging I got following error "Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your main function has STAThreadAttribute marked in it. This exception is only raised if a debugger is attached to the process."
so I used the following code:
Dim ofdThread As Thread ofdThread = New Thread(New ThreadStart(AddressOf ShowOpenFileDialog)) ofdThread.SetApartmentState(ApartmentState.STA) ofdThread.Start() Private Sub ShowOpenFileDialog() Me.ofdGetNetPath.ShowDialog() End Sub
now on button click, OpenFileDialog is shown but it is not showing Mapped drive or Network location... what should I need to do to show the mapped drive or network locations?
I am using this code to parse an html file for image locations:
Dim htmlDoc As String = IO.File.ReadAllText(path, System.Text.Encoding.Default)
Dim Regex As New System.Text.RegularExpressions.Regex("img.*srcs*=s*(?:""(?<1>[^""]*)""|(?<1>S+))")
[Code].....
How would I change the regex string so that it leaves off everthing from the img to the src=, so that I'm just left with what's in between the quotes? Note that sometimes there is stuff between "img" and "src=" and sometimes there is not.
I have a program that must copy a file to 3 locations, the local hard disk, a USB drive, and a network location. I have the file (about 70mb) loaded into a byte array. My quesion is, since I'm not actively modifying the byte array, can I impliment a form of multithreading where all 3 threads read the same byte array at the same time?

View 1 RepliesThis is the code I have in one button and I have 2 listboxes that will be filled with the info it gets.This code should compare 1 avi file to one jpg file and see if they have the same name. If YES then it will add the avi path to one listbox. If they don't have the same name OR the .jpg doesn't exists it will add avi path to another listbox.. But currently it is adding the avi name to both listboxes.

Working on a small program that saves a file path to a text file and then when run opens the text file reads the file path which will be the only line in the file. I believe I have traced my problem due to the character that would be in the text file when hitting enter to start a new line which I assume is "vbCrLf".

View 2 RepliesEssentially I am trying to replicate the Windows 7 (In-Windows) activation key TextBox form. The Form where it will auto capitalize letters, remove or deny all non alphanumeric characters except dashes every 5 characters that will be auto-input.I assume this can be done with a fairly complicated replacement Regular Expression but I cannot seem to create one to fit the needs.
This is an Example of what I have right now, but it creates an infinite loop as it removes all characters including dashes, than adds a dash, which changes the text and removes the dash again.
