I have a function that is called getWinTemp, it is below, the point in this is to create a temp file in the directory and then stuff it full of calculations and then delete it when the code has finished with it, does this code do that in .net??
Public Sub cleanInput(infile As String, width As Integer)
tempfile = getWinTemp
Name infile$ As tempfile
Open tempfile For Input As #1

View 1 RepliesHow to get the file path of the Temp directory (% temp%)? I use Visual Basic 2010
View 1 RepliesAm trying to copy contents of file temp.fxl to temp.seq. I want them to look exactly them. I don't want to copy the file though. I use the following code
Dim fs As New FileStream("c:\fxlate\output\temp.fxl", FileMode.Open, FileAccess.Read)
Dim s As New StreamReader(fs)
[Code].....
With such simple code, the last line in temp.seq is truncated as attached and the size of the file is smaller than temp.fxl. See attached files. What do I need to do on the above code. Is VB.NET failing to write 1024 characters on one line.
How would I create a dir Inside %temp%? Then extract the file to it and Open a That folder. So far this is my code.

When I want to maintain code readability and keep things neat. I would create temp variables . Below is one of my functions that uses it. Is it a bad practice? I would create temp variables cost more memory ?

i know how to shell an existing batch file with shell, however, the code inside the batch i want to change depending on a certain variable,so is there a way i can write a textfile and save it as a .bat then run it, and delete it after, so the user does not really ever see the .bat file (so it seemingly looks like the program itself is running the commands)
View 4 Repliesi have a project that im working on & out of curiosity i went to the "clickonce" wizard were you publish your application for deployment (setup) after doing that it created a folder for publish & in my solution explorer it created a file project1_TemporaryKey.pfx
what is this .pfx file? after removing it from my application & closing the solution it started giving me errors & i was unable to re-run the application until i restored the file & added it to the solution.
I have program that on first run will run after installed will setup a server connection. The next times the program is run it will not execute this code to setup the server as it was done in the first run.
I can't use clickOnce IsFirstRun as the customer doesn't want that used for installation.I am using MSI to create the setup. I right click setup / view / Registry. I create a key value, example "HKEY_CURRENT_USERSoftwareReality", "App", "Installed"I set the property AlwaysCreate = false, and DeleteAtUninstall = true.
My big question I don't want to create the key value when the application is first installed. Only delete it when uninstalled.My code for checking for the key value:
Code:If (My.Computer.Registry.GetValue("HKEY_CURRENT_USERSoftwareReality", "App", Nothing) <> "Installed") Then 'The program is running for the first time so create key value My.Computer.Registry.SetValue("HKEY_CURRENT_USERSoftwareRealitySolutions", "CodeRed", "Installed") 'Setup server for the fist time Else 'The key exists so go no need to setup the server'Do something else End If
The key value deletes on the uninstalled - which is what i want it to do. However, it always creates the key value when installed. i don't want it to do this. It should only create the key value in the code.Can any tell me, when setting up the registry in the setup project, is there a way to stop it from creating the key value when the program is installed.
I have a case where the user or client attaches the document and the document is saved in the data base as byte stream.Now I need to get that binary data and convert it to the corresponding format and save the file in the temp folder in client system using VB.net and then I want to get the path where it was saved so that I can send it to the data base for sending DB email.

I am trying to create an MDB as a temp file to save some tables and query them. After creating, I can't delete it ... Even before it is actually used. The process cannot access the file because it is being used by another process.

View 3 RepliesRight now I upload a temp image file, delete the original, and then rename the temp to the original. Is there any way to rename without deleting first? I am doing this in a loop for a webcam program and when I delete the image, it shows a broken image if it is being veiwed right then. I wish I could allow it to overwrite when calling the rename. FYI, I have to upload a temp image first because if I upload the original, it will show as a broken image or partial at timed when being viewed.

View 4 RepliesI'm running Visual Studio 2010 on a terminal server, and have been, with relatively few problems, for some time. This morning I fired up my PC and over the UK's long weekend, the following issue seems to have developed.I've got a bunch of projects (but not all of my projects, and not all of the projects in a given solution) complaining that a particular file (which does not exist on the computer) cannot be opened, and so those projects will not compile anymore. Here's the error:
Error 31 Unable to open module file'C:Users[username]AppDataLocalTemp2.NETFramework,Version=v4.0.AssemblyAttributes.vb':
System Error &H80070003&
I could simply copy the file into that directory and be done with it, I'm pretty sure that will work,EDIT: Okay, now things have gotten to a whole new level of weird. I've rebooted the server, I get the same error message, only now the file it is asking for exists and can be opened in Visual Studio with no problems. another part of the IDE still insists that it's unable to open the module file.
EDIT 2: Can't delete the file because it claims to be open in another program, but I've logged off and logged on again, and there shouldn't be anything accessing it.
EDIT 3: Because there's a wall of comments below his answer, I'll mention here that Jared's suggestion to delete the SUO file for the solutions having the problem (not files specifically to do with any of the problem projects, strangely) was what solved this, eventually.
I am creating a program that allows a person to enter details about their farm, stock, and machinery in order to electronically keep track of all of the information. I have created the forms and done all the coding for the data entry, and now what I would like to do is allow the user to delete a single record from the .dat file. I am able to delete it from the LstBox (using a "Delete Entry" btn coded simply with
lstvehicles.Items.RemoveAt(lstvehicles.SelectedIndex)
(using the vehicles section for examples)), but I am unsure of how to delete it from the .dat file as well, to prevent it reloading upon data change / program reload. Also I would like to be able to have a reminder come up on the program start up that gives a reminder to (in the vehicles instance)when a vehicles rego is due, the date being associated to a date that is entered into the same lstbox data using a datetimepicker.

View 5 RepliesI have an OpenFileDialog. I want the program to copy the file that the user selects to my "temp" folder. If the user doesn't select any file, then it doesn't copy any thing. Here is my code:

System.IO.File.Copy(Form6.OpenFileDialog12.FileName, Temp & System.IO.Path.GetFileName(Form6.OpenFileDialog12.FileName))

I know that Deleting a specific line in a sequential text file is impossible but instead copy the needed lines and not copying the unneeded ones to an output file .. killing the old one and renaming the new one with the same.. I can't make this step...
That is my record file

Input #1, CustomerName, CustomerHomeAddress, CustomerBussAddress, CustomerTel1, CustomerMob1, CustomerID, DateRent, CarRegPin

I made a form that when you put your CustomerID in Text3 Box.. it access the records and make some calculations. now.. The customer will return the car.. Then his data should be deleted.. I want to know how to make that when I enter the CustomerID and press on the Command button .. It copies the other lines to a new output folder and doesn't copy these ... So it appears to be deleted using this way..
