View 1 RepliesI 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.
View 1 RepliesThis is my first time working with VB, though I've been working with VBA for a couple years now to automate office routines at my work. At my last job, I saved about 3 hours a day with my automations, and at my current job, I'm shooting for about the same. The problem is, though I have a high affinity for computers and technology, I never studied to be a programmer, and so I really can only tweak code I find online, and then eventually build up enough of my own subroutines to accomplish the tasks at hand. This is why I'm posting here on this forum, I've reached my wits end for what I imagine is a relatively simple problem. This was initially written in VB 6, but I imported and converted it with Visual Studio 2008, and it runs fine. This demo code is set to populate a PDFwith some sample string text. What I want to do is to replace the string text with a reference to data in either an Access or SQL database - I prefer Access, but either will work. Here is a sample of the demo code I'm working with:
[code]...
On this last line, I want to replace the "1" sting text with a reference to a temporary 1-row table I'll be generating from an Access Query, with Field Names to match the Form Field names of the PDF, So I've setup an Access DB with the following configuration (in reference to the path, I'm using Vista x64):
[code]...
I have also imported this table as a dataset (my understanding is that the import into Visual Studio 2008 makes it a typed dataset?) so either referencing the access DB directly or the imported Dataset should work. I can also setup the Access DB as a SQL DB instead if it would make it easier. Now, if I was programming in VBA, I might do something like this:

View 6 RepliesI'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:
[Code]...
I've found a script on a microsoft site which should clear the temporary internet files folder:
Const TEMPORARY_INTERNET_FILES = &H20&Set objShell = CreateObject("Shell.Application")Set objFolder = objShell.Namespace(TEMPORARY_INTERNET_FILES)Set objFolderItem = objFolder.SelfstrPath = objFolderItem.Path & "*.*"Set objFSO = CreateObject("Scripting.FileSystemObject")objFSO.DeleteFile(strPath)
For some reason this script doesn't work for me. It get's the proper folder becauseI used Wscript.Echo objFolderItem.Path to print the path but the files are not deleted.
what a good code to delete my "Webbrowser1" cookies (not my IE7 cookies !) I would also like this program to delete the Webbrowser1 History & Temporary Files as well, but mainly the cookies. I would like for this program to either delete cookies by a simple click of a button or to set a timer that can erase the cookies every few minutes. Also, if it could show the current cookies before being deleted.

View 1 RepliesI 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.
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".

View 1 RepliesI'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?

View 7 RepliesI have looked through the entire internet (well that's what it feels like) to find this out.Tables - Authors and Titles add new title must be linked to an author, so I need to check that the author exists, if so, update the titles table with the user data from the textboxes. If the author does not exist, I need to insert the author first & last name into the author table, then the title info into the title table.this is in VB, using ASP.NET, and my database is a file, I'm not using SQL server, just Visual Studio 2008.

I'm trying to insert and update from a table in MSAccess I've declared everything: Connection, DataAdapter and Commands.I didn't use the Command Builder instead I supplied my own Queries.My problem is if I add three rows to my table all the three rows in my database have the same values from the first row. It seems like the parameters are stuck on the values from the first row. [code] I'm using a DataTable with my DataAdapter since I'm dealing with a single table.I'm filling the table with a parametrized query, and updating it with the same dataadapter.I'm adding rows to my datatable and manipulating the table through code. I know that my data is there and every row has it's own values, I can see them when I debug my program.
