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

How would one create a temporary copy of an image to use, and then dispose of it once finished? System.IO.File.Felete returns an error, stating that the file is still in use. How would I make the file delete-able? [code]As you can see, Ghostscript creates an image in a temporary location, then sets it into the pbPreview PictureBox.

I'm almost ascertain there's a better way to do this but for right now I'll go with this. This is using WinForms, NOT on a webpage.
In Visual Basic 2010, I would like to create a form that uses a datagrid view pulling rows from a temporary table made at run time. When the "Submit" button of that form is clicked, the rows from the temporary table will be copied into the regular table. (This is being done as there is no ID# available until AFTER the form is submitted. The ID# is needed because the rows made in the temporary, as well as the entire form, will be associated with THAT number.)
how can I dynamically create a temporary table in MSAccess OR how can I use a datagrid without associating it with a table?

I created an application that when a user logs onto their Windows account, a Form is displayed outlining the current Computer Usage policy set by the insitution and gives the user two options either Agree or Dis-Agree. The two options are in the form of buttons, with events that depending on what the user clicked, will create a log text file at a specified location, with enteries of Date,Time,CurrentUser, and if they agreed or disagreed. If they agreed the application after creating/amending the file will then terminate, otherwise it will update the file and then force Windows to logoff the current user.
Now I made a shortcut of the .exe of the application and placed it in the startup for all users, and yes the application loads at startup for all the users following the procedures mentioned above. The problem I am facing is, that if the current user logs off, or is forced to log off, and another user logs onto Windows, goes through the whole ordeal mentioned above, the application is denied access to the logfile that was created under the previous user, and thus crashes.
So my question is, how can I created a text file using vb 2008 application, that is accessible by multiple Windows users. I have even tried changing the location of the created file to the shared folder, but the end result is the same.

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))
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.

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 want to make a program that is similar to Windows Explorer. It will have a button that when you click it it opens a FolderBrowserDialog and it will have an area that displays the contents of the selected folder. I want to have a label that displays the current folder path (i.e. 'USERDocuments...') and I also would like a feature to search all files on the computer.Also, is it possible that when I click on a file in the contents of the selected folder it displays its information (i.e. Name, Size, etc.)? And can I also make it so that if you double click on another folder in the current folder's display it opens that folder? And can I have a button to go up one directory?

I have written a program in Visual Basic 10 and all is well. I have published it and have been burning the result to a cd and installed it on various computers, however it is the click once app, which has been fine till now. What I need to do now is to have the program install the .exe file and associated files (non click once app) to a specific drive on a computer or network computer. I have searched the net for instructions on how to initiate the windows installer and have failed. is there a program that you can select the source files then point to the installation folder tell it to go and an installation package gets made that I can burn to disk.

I'm writing an application that I want to keep status text always on the taskbar. Some programs like Windows Media player create a toolbar that can be added to the taskbar. Is there a way to do this in VB.NET, and if so how ... ?
I can create a notifyicon, and although it can be used to display notifications I need the text information to always be displayed... I could have used different icons to show a change in status in the notifytray but I really need text to display the status.

I'm trying to create a windows user control project that has a textbox placed on it.I want the textbox to fill the user control window.I've built the control and added it to another project, but it isn't behaving the way I want it too.When I drag and drop the control from the toolbox onto a windows form and try to resize it, because the textbox.multiline property has been set to True, the Textbox resizes horizontaly and not vertically (just like normal textboxes do) however the underlying user control window resizes which is undisireable. How can I get the user control window to stop doing this.

In our application, we have a number of Windows Services (more than 30) that must run behind the scenes to process data at given times throughout the day. I was attempting to create a BaseService class that I could inherit from that would log to our database when the service started or stopped as well as some other common functionality. However, I ran into a show stopper in trying to create BaseService as MustInherit as we have a number of MustOverride properties. The issue lies in:
<MTAThread()> Shared Sub Main()
Our code is all in VB (as you can probably tell). Given that it is a Shared method, I cannot have it be overriden (i.e. make it MustOverride). Without this method, the code will not compile, however it will not really work in the base class. The code in this method is:
Dim ServicesToRun() As System.ServiceProcess.ServiceBase
ServicesToRun = New System.ServiceProcess.ServiceBase() {New BaseService}
System.ServiceProcess.ServiceBase.Run(ServicesToRun)
The BaseService (the name of my base class) cannot be created because it is specified as MustInherit. And therein lies my problem. I cannot create this in the Base Class and cannot override it in the inheriting classes.

Creating a pdf document using Itext is quite simple if your application is a web application because you can find samples to help you out all over the web. Creating a pdf document for a windows application on the other hand is not so easy. I cannot find a single sample online anywhere.so far this is what I have:
Private Sub PrintDefaultReport()
'Declare PDF document
Dim doc As New Document(PageSize.A4, 40, 40, 0, 35)
Dim MemStream As New MemoryStream
[code]....
What is the above equivalent for a windows application?

I'm wondering how I would go about creating a program that once installed was a windows toolbar. What I'm trying to do is similar to the clipboard, but I want to customize it to my own style. I work in a data entry job and many of the bills we enter have similar information that I'd like to be able to enter without repeated typing. I'd like the toolbar to be docked to the top of the screen, and have several buttons on it. Clicking a button, while having a focus in my data entry program, would paste the button's text (or the full text of what the button caption represented) into the selected field. Alternately, if focus between multiple applications is too difficult to try, then clicking the button would highlight the text and copy it to the windows clipboard, so I could then click back into my data entry program and hit ctrl-v. I dont need help on the program itself...just on how to make it as a windows toolbar, if possible.
