View 4 RepliesI have some code that works fine when I need to delete some image files from a directory on my web server:
Dim ImageURL As String = dsImages.Tables(0).Rows(iImgRow).Item("ImageURL")
Dim physicalName = Server.MapPath(ImageURL)
oUpload.DeleteFileFromServer(physicalName, iAdid, iImgID)

Basically what I need to do is to insert into table Reservation a vehicleID, startDate and endDate.
I can do that fine but I'd like to validate it so that it cannot be inserted for that vehicleID if the current date is <= endDate as currently I can just keep adding to the Reservation table on the same vehicleID
This is just the simple insert SQL statement.
strInsert = String.Format("Insert into Reservation (VehicleID, startDate, enddate) VALUES ('{0}','{1}','{2}')", vID, now, now5)
I am a ASP Classic Programmer, professionally for a little over a year, I have developed some rather nice sites, including the one in my signature (Still a work in progress).
I have been forced to use ASP.NET (VB) for a FileUpload control, as it offers a self controlled way of creating Thumbnails, without the use of 3rd party controls, which is great, as my hosting server does not allow for 3rd party installs on their servers.
So.
The code below is what I have so far for connecting to the database and displaying a record is the "cookie" exist on the users computer.
Unfortunantly, this is not working, and to be honest with you, their is not a whole lot of resources available to show how to do this correctly.
So I am stuck with a lot of post and hoping that someone can actually assist me with this and tell me what I am doing wrong and maybe correct my code.
I am getting an error about the "Connection is closed"
If you want to re-write my code, I prefer something simple and basic, as the only thing that I am doing to checking rather the user is logged in, and if so, display a record from the database. I am NOT in the need for the DataGrid, so please do not suggest it, as I am only needing to check this one thing.
I would like to also add, that I have successfully contect to my database with the FileUpload control and save file names of the images uploaded, so I know that my connection string is done properly> But, for some reason the "SELECT" statement is causing a HUGE issue. (It was easier to insert, than to select, I am not use to that)

I have this code for my update checker. It loads a blank text file on my server containg the current version. I have it set to naviagte to this url then searches the web browser for the current version. If it cannot find it then there is a newer version, and a button becomes visible which lunches a webpage that has the current version. I would like it to loop my Check_for_update code until the webbrowser1.statustext = "Done" Below is the code i have but it doesnt work for some reason. Private Sub Update_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Question: How to pass the current user on the web page from the IIS server to the Reporting Services Server.I have seen this topic throughout the forums. However, the answers are always hard code the user in web.config - use a login window and pass those fields to the IReportServercredentials or create one user for everyone.
When the person who asks the question comes back and says that doesn't work there is not answer.Does anyone know how to do this? I have VS 2008 ( and 2010 ) I am sending the info to SSRS 2005 server.As anyone using SSRS knows that if the reports have parameters and udf behind the report to inspect who the user is, then you have to pass that user to the report.

I have been programming steady with vb.net for a year now and was all happy about using the List view and email etc from web sites. I even used a reportviewer to pdf to email attach, cool. Now I feel quite lost and realize I have not been using properties, etc. That is my background.
Multi-User Chat Program (Server & Client) with Main Server?
View 1 RepliesI made a simple TCP server (I've found the example on the web) in VB to receive data from about 40 TCP clients.The clients are not synchronized but sends data about every 18 minutes; the problem is sometimes several clients sends data at the same moment, so I can't receive data.I also made a second program that reads the data (server program writes data on a file, read from the second program) scheduled.
My question is this: I've seen on the web examples about Multithreaded Server Socket Program, so I suppose this could manage my 40 clients (but now the clients are syncronized and send data at the same time in client mode) or is better get data (I have a central client that asks data to all 40 devices in server mode)?
Second question: can I make a single program where I run both TCP client and TCP server at the same time?
I have to say, the search box in this forum is questionable. searched for this:My.Application.Info.Versionand got lots and lots of hits and not one post actually had those words.....Anyway, I want an About msgbox to popup with the publish version displayed.In my project properties, under the Publish tab, Visual Studio has the following:

We are thinking about changing our current database system, MS Access 2007 front end and MS SQL Server 2005 backend to using a higher level language such as Visual Basic .Net. I wonder if this is the BEST solution for data management? Currently, among others, we have two big database programs that handle more than two hundred users and it's crashed often. That's the reason we think about changing to something that can handle these database programs effectively preferably using MS technology such as .Net.

View 18 RepliesI am trying to create a program in Visual Basic which will measure the performance of the CPU with every core, one at a time. In this program, I decided to place a couple of text boxes that display the processor speed and the actual processor speed. I need to get the actual processor speed to update and I have tried doing this already using a timer set to tick every second. However, when I load the program it runs really slowly and prevents me form doing anything within the program, including trying to close it down, and all it does is updates the text box every second. I have looked in task manager to find out how much CPU the program is using and it shows that my program is using 0 - 3% CPU.
Here is the code currently use
Private Sub Timer3_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer3.Tick

View 1 RepliesI need some help in the creation of a program to generate a security code based on the current date.
