Create A Temporary File In Vb 2005?
Jan 21, 2010I 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))
2) listbox SelectedIndexChange = search fullname.dat (temporary file)
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.

View 3 RepliesCreate New Projects In Temporary Directory?
Jun 8, 2012Basically 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".

View 3 RepliesHow To Create ' Temporary' Graphics With Text Changed Event
Feb 27, 2011I'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?

C# - SELECT, Manipulate Data Temporary Using SQL SERVER
Aug 9, 2011The DB has a field "end date" and 1753/1/1 is supposed to be the value representing nothing, as we cannot assign null to datatime in sql server..
In reporting application the select querry used, gets the data including those 1753 date values. good
Problem 1753 date causes hell with report calculations. there are a lot of calculations in the report and changing the code to ignore 1753 will be a headache, so i was thinking Is there a way to tell sql server,
SELECT *
FROM TABLE BUT IN END_DATE
WHERE VALUE='1753/1/1 01:00:00.000' REPLACE WITH PARAMETER1
CRUDE EDIT (donot have access to debugger currently)
i cannot remember but i get an error like "nothing should be mapped on something" when i insert record with null date! THIS HAPPENS ONLY WHEN USING VB.NET in csharp it works fine. do you know why??
Manipulating Data From An Oracle Temporary Table
Sep 7, 2010I have a VB.Net application that populates an Oracle 11g global temporary table. I can see data in the temporary table by loading it into a grid and everything looks correct.However, when I call an Oracle stored procedure from VB.Net that would manipulate the data in this temporary table, the stored procedure reports that my temporary table is empty.I understood that data in an Oracle global temporary table should be visible to all sessions.

Creating A Temporary File In VB On Windows 7 PC?
Nov 15, 2010I 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!

View 1 RepliesJquery - Passing Client Data To Server To Create Excel Or CSV File?
Jan 9, 2012I'm creating a reporting web page as part of a standard VB.NET web application. The page is data driven, with jquery making calls to a web service local to the application to get values of elements that are dynamically created in the DOM. Ultimately these dynamic elements and their values are all wrapped up in a JSON object, so that part of the client side is fine.
Right now, I can pass that JSON object to a method in the web service which creates an SQL Data adapter from the values and queries a database. My ultimate goal is to have this client JSON data be used to query the database and construct an excel file to send back to the user, or failing that a CSV file.
It's my understanding (from working with PDF file generation) that this type of function can only be done on the server side of the web application, not even from the web service (i.e. I can't have the web service return an array of bytes and have JavaScript/jQuery present that as a file).
So, how do I go about this? Now I have my JSON object on the client side, where should I be sending it, how, and how do I go about returning my file?
I've read about either storing the JSON in a hidden field and having the server take the elements value and go from there, or using AJAX to send the JSON to the server just before a postback is made to fire off the server-side function to run the query and return the data.
I just need a little guidance, and a little help understanding where to use the hidden field, or what I am actually doing with the pre-postback AJAX call.
