I just need to know how to create a temporary file for each line of a file when it is selected in a listbox, so that i can split it and assign each part to textboxes.
1) create temporary file from variable for each line of a current file (each line represents a contact, and temporary file's name is the contact's fullname(variable as string))
3) split the content of the fullname.dat file and assign each part to display in textboxes the only thing i got a problem with is creating the temporary file.
I want to create temporary text file because after I use the text file, I want to delete it. But I just create the text file and write into th text file and at the end of the process, I want to delete it. However, the system won't allow me to delete it as it being use my
Dim objWriter As New System.IO.StreamWriter("C:\Blind Holes.tmp") objWriter.WriteLine(lineP(1))
i am using visual studio 2005 and database sql server 2000. i want to read table of database and readed data insert in temporary table again update that inserted record.
Basically I've been using the VS2008 Express editions for the last few years. With the express editions (with the exception of C++), by default when you create a new project, the project files are all stored in a temporary directory. When you select "Save All" for the first time, VS would prompt for a project directory and then you could save the project into your regular project directory.This is behaviour I found exceedingly useful, as many times I create very quick, simple programs to do 1 thing for me before never needing them again.Once I close VS, it prompts me whether I want to save the project, I select "Discard" and everything's all good; my project directory doesn't get cluttered with useless directories for 1-time projects and everybody wins.
However, with VS2010 Ultimate I've noticed that the default behaviour has changed and all new projects are created directly into my Project directory (yes I'm aware I can change the directory when creating the project, but that's a needless waste of time). This has led me to reverting to express editions whenever I want to write a small program, which isn't too bad at home, but at work we only have VS2010 professional. Every time I create a simple project I have to remember to delete the directory later or face having a directory of "WindowsFormsApplication1000232131231".
I'm in an upper level industrial engineering class in which we're learning some entry level VB programming. We're working on building a program to solve the travelling salesmen problem (finding the shortest path through a collection of cities while visiting each only once) and I'm trying to add some 'fancy' to it so I can learn some more skills. The basic program is designed to load a bitmap file of a map into a picture box and a text file with the xy coordinates of any city positions. From there, the user can plot the cities with red squares, draw a random tour through the cities, or tour the cities by always visiting the nearest neighbor not yet visited. The modification I'm working on is a method of pointing out a specific city with a black square by entering the city's number (determined from the coordinate file) into a text box.
Private Sub TxtFindCity_textchanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TxtFindCity.TextChanged Dim ObjFindCity As Graphics = picShowMap.CreateGraphics Dim City As Integer
[Code]...
So far, the program works, but I want the black squares (but none of the other graphics) that are created to go away once the text box is cleared. As of now they just hang around on the screen until I refresh the entire image with a 'clear map' sub. Any suggestions on how to accomplish this?
I am wanting to pull data out a select table and wanting to use it locally as Read Only data I am stuck on how to write the data to the local Temporary table[code]...
Below is my code for DELETE button.

At the same time the list view must able show the total current balance from the deleted trnsaction.
I have a VB program that creates a temporay PDF file then opens Outlook and attaches the file. I create the file in hte application path (the location that the program is running from - normally C:Program FilesProgamName This works fine in XP as it appears there are no crazy permission issues. However in Wondows 7, the file does not appear. There are no errors, the file does not exist in that location.
I've changed the path to the root of C:, however this doesn't work either. I suspect it's something to do with W7 virtualisation, so the question is where can I create a file that I can then access again?
I was trying to avoid creating it on a share on a server, but it's looking like this is the only place to put it as there doesn't seem to be many places a user can write files to in Windows 7.
Surely there must be a location that users can access (without being administrators) to create files. Don't even get me started on the fun I have had with the registry in W7!
I've got some temporary files I've created in a folder suffixed with -tdf (stands for to delete file), I'm deleting this file later, but when I check the folder it exists in, it's still there. The code is pretty much this:

I have a problem with the temporary internet files. I know how to locate the folder and all the rest, but I'm going to see what second c 'is in the folder with Explorer I see dozens of files, but when I go to see through code, I see only two files, index.dat and desktop.ini. I thought that the index.dat file is a kind of file that contains the files that I see through explorer, but it seems too light, and still do not know how to copy the files it contains.
I have a program where by I want to copy a temporary (in coming file from an email attachement) and I want to paste this onto my form (listview control perhaps??)

I need to have some of my columns in an integer value not string.So from I can tell so far and I am extremely limited, if I use WriteXml this should write the schema and the data and the readxml will read the schema and the data, although I dont see the schema in my xml file that gets created from my oDS.WriteXml/if I use oDs.WriteSchema I can view the schema file that is created. Thats how I determined the schema is creating all string vlaues for each column..All the fields are of String value as was pointed out, so how do i create my own schema file? or rewrite the one that is created.[code]
I need a bit of advice. I am working on my project with the listbox. I know how to create a source to get the strings from the text file using ReadLine method, but I have no idea how to split the strings in the text file by on the third commas and ignore the other strings while select with the matched strings on the listbox for each row.Here it is an example listbox Here it is an example items on the listbox
random item 1 random item 2 random item 3 random item 4 random item 5
And here it is an example text file.
example strings one, any strings 1, any random strings 1, other strings 1, final end of strings 1 example strings two, any strings 2, any random strings 2, other strings 2, final end of strings 2 example strings three, any strings 3, any random strings 3, other strings 3, final end of strings 3 example strings four, any strings 4, any random strings 4, other strings 4, final end of strings 4 example strings five, any strings 5, any random strings 5, other strings 5, final end of strings 5
The listbox is display the list of an example items, so if I select the "random item 1" item on the listbox, it read the strings through in the text file on the first line to get the strings on the third commas in the same line which it is (any random strings 1) to split it while ignore the other strings (other strings 1, final end of strings 1) that come fourth and fifth commas. So, if I select the "random item 2" item on the listbox, it read the the strings through in the text file on the second line to get the strings on the third commas in the same line which it is (any random strings 2) to split it while ignore the other strings (other strings 2, final end of strings 2) that come fourth and fifth commas and so on...That is what I am trying to achieve by select the each listbox item to get the correct strings for each line in the text file that come on the third commas while to ignore the other strings.
i need to create an application(VB.net or VBA) which will convert text file contents into excel. u the contents fromt he text file have delimiters(special characters).The condition is while converting it should remove all the delimiters and paste teh content between two delimiters in to one cell.For Eg:
I am attempting to have my program select a file, create DataTables and then perform some other functions. I want to be able to open another file and re-do the same steps.The problem I am having is that I add columns to my Datatables and when I try and to open another file while one is already open I get a message that a column of xyz is already added how do I properly "clear my datatable" or perhaps that isnt even the correct approach? Here is the code I have that Opens a File

This was working at one time but after adding to my project I must have placed something in the wrong place inadvertantly or it has soemthing to do with adding columns,?
