View 5 RepliesI am developing a chat application using online connection to a mysql databbase. But i am facing a problem. After 10 minutes, MySQL closes all the chat connections because of the 600 seconds timeout (has been set by the host service i am using). I don't understand why is that happening cause every piece of my code which needs data from the database opens and closes the connection (i mean that it dosn't maintain the connection after the query's execution). If i .close() and .dispose() the connection, it still appears in mysql at sleep mode (it terminates only if i exit the program).
Dim MySQLCon as New MySQLConnection
Dim MySQLCom as New MySQLCom
Dim counter as Short

I have the following problem: I select a customer from a dropdownlist and then the gridview should load all items of all orders of that customer. I have the following query:
Dim allorders = From ord In db.Orders
Where ord.CustomerID = Convert.ToInt32(CustomerDropDownList.SelectedValue)
[CODE]..............
I also tried to modify the query as follows:
Dim orderitems = From oi In db.OrderItems
Where oi.OrderNumber = (From From ord In db.Orders

But this does not work. I just started using LINQ.

I'm creating an application software. It has many features, which is in the base version of the software. And people could buy my software (which will be enough for most of them since it had all the common features needed) and use it. But some of them might need additional features to this version.So, I can add new features to the base version of my product and provide them a custom or extended version.
But my question is, how can I effectively manage these versions of the software while updating (or upgrading with new features which are common to all of them)
[Code]...
In the above example F1, F2, F3, F4 & F5 are the features available common for all editions of my software.Whereas, A1, A2, A3 & A4 are the additional features added based on customer's request.
So, in another related post, i got the chat to send to a java server, cool.Now, it's a matter of sending it back to VB.on the server side of things, (in java), I am using the following

So far, I have always run applications within the IDE, using Debug Mode.If I publish an application will I have to add code to repaint Picture Box graphics?In the IDE, my Picture Box graphics never get disturbed by running some other application or minimizing my forms.
I have noticed some discussions which suggest that code is needed in the Paint Event Handler in order to redraw graphics which disappear due to minimizing the form or running another application which displays a window covering my application.
I want to be able to drag data from one DGV to another. When the drag is completed, I want the backcolor of the cell that the data was taken from to change to red. I will add a "trash" icon that will accept a drag and drop from the 2nd DGV to remove the data from its respective cell. Finally, when the cell is trashed, the corresponding cell from the first DGV will return to it's normal backcolor. My application is going to be used to schedule clients with employees for a home health care business. The reason I want all of this is so the user has a visual aid to show them that times have been used already to avoid double staffing. i also have to figure out how make all of this unique to each client when flipping through the DGV/binding source.

I've gone through about 16 hours and two packs of cigarettes trying to figure this out. First a little background. I was using 6.0 up until 2004 when I went to prison. I'm out now, and trying to relearn the trade, using VS 2005. I'm currently porting some 6.0 code from another project, SpyCast Webcam Studio, into VB 8.0. It's disheartening, to say the least. None of the old built-in subs/functions work anymore, so I have to scour the forums to relearn each and every function.The section I'm doing now takes a snapshot from the webcam (Video API --> PictureBox --> Save as Jpeg), then upens the file to upload it to the server via HTTP POST. I've been using this code in SpyCast for years with no trouble, but I spent many hours trying to piece together the right code to open the binary file to read its contents. I pieced together two methods I found around the forums, one using FileStream() though the code I found wasn't for binary files, even though it said it was, so that code doesn't really work. Method two uses Microsoft.VisualBasic.FileOpen() and works better.
Here's the kicker. By the time I run through the rest of the rigamarole of uploading the file, by the time I read it on the webserver, it's *slightly* corrupted. It's a valid Jpeg, no errors, but the picture looks like when I use to watch the Playboy Channel when I was a kid scrambled with weird colors and whatnot. [code] Each "chunk" is basically one "line" of the file. It looks like a single LineInput() return is the text between two carriage returns. Am I correct? I tested this with a flat text file, and it looks true. However, That one input line returns the text or data with the carriage returns *stripped*! ***?!? =( Fine, I have no problem adding my own vbCrLf to each LineInput(), if I were opening text. but this's binary. A character could be Chr(10) or Chr(13), both of which are removed from the original file contents.So I could very well need to use something other than LineInput(), but I haven't found any other examples on the web using this method.
[code]A customer can not exceed a debt load of 36% of their gross monthly income including house rent or a mortgage.[code]I basically know how to code this. I get the information from the user (income, rent, and other monthly payments) and then ask if they have good, ok, or bad credit (this will be the percentage part) and I know mostly what to do, but the hardest part is the actuall coding part, basically the calculations part, im always confused on what to do, my example shows basically what to do and I know how to get the users info, but how to program the calculations, is where im also stuck at My example is (the money for the income, rent, and other monthly payments the user entered already)
1. If there monthly Income is:$2,000.00
2. Monthly Home Rent/Mortgage:$500.00
3. Other Monthly Payments (alimony, child support, student loans):$100.00
4. Then there allowable Monthly Car Payment:( 36% of 2,000 (income) = 720)( now I subtract debts 720 - 500 (rent) - 100 (other) = 120) :$120.00
5. Display Maximum Car Value (interest rate based on credit):Present Value Function (16% per year (this is where I check one of the boxes for the credit, which in this case its an ok credit), 6 years (I have to keep it at 6 years), 120 (this is the allowable monthly car payment) per month)So basically PV((0.16 / 12), (6 * 12), 120) : $5532.03.

It's a basic Access database driven e-commerce site. I have a home page, a products page, an orders page, an order confirm page, a shopping cart page and a view current orders page. The site uses an Access database with three tables. A Customer table, with all of the customer details, (FirstName, LastName, EmailAdd, CardNo, CardEx, SortCode, DeliveryAdd, Postcode)A Products table, with all the product information, (ProductID, ProductName, Price, ProductType, Images, ProductDescription). And an Orders table which contains CustomerID and ProductID.I've managed to get the orders page to work, this leads to the order confirmation page which displays the details the customer just placed.Here is what I have in the order confirmation page load event so far. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
[code]...
This returns this error "Syntax error in FROM clause." I'm guessing my SQL code is wrong. I noticed when I placed the order in the order page it added an entry in the Access database where the generated CustomerID was 12 on the customers table and 4 in the orders table. Shouldn't these numbers be the same when they are generated?
So, I want to implement my own binary serialization. I'm looking for some examples to head me in the right direction.

View 9 RepliesI'm currently in the middle of attempting to create a query that will be used so that the application user will be able to search the a customers id number. I'm completely new to adding queries using the query builder so I've become slightly stuck on trying to get this to work corrently.
I have a database which is set up and in this case the table is called 'cid' which defines the customers id column in the database, this is a primary key and the column has a data type 'AutoNumber'. I've become stuck as I'm not sure what I would have to put into the filter to make this query work.

I have to calculate the maximum mortgage possible for a customer. If it is a single application, the customer can borrow up to three times their salary plus any savings and investments they may have.
If it is a joint application, the customer can borrow 3 times larger salary and 2 times the smallest, also borrowing against any savings and investments. In either case, the applicant is not allowed to borrow in excess of 90% of the purchase value of the property (including stamp duty and legal fees).
I have declared everything and done out the code, yet every time I calculate the max amount they can borrow, it comes up as 0. My code is below if anyone can spot problems.Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) _
