I created a app using VS2008. It works fine in win xp but not in win 7.For example, I have code in one combobox leave method to load data into a datagridview, it failed to load. (blank).Do I need to do something in target pc which runs win 7?
View 5 RepliesI created a background thread that get's data and returns it to the main thread; this works. Now I want to be able to stop the SQL request from the main thread (probably on a button click). This is my test code for creating the thread (working):
[Code]....
How can I access the background thread to stop the query on demand? Do I need to set a flag on the main thread telling the background thread to stop running then have the background thread poll the main thread at intervals? I was trying to look for an example but I wasn't able to find a good one.
Right now i have a form in the VB where there are 2 combobox in it. user can choose from a range of products that comes together with some description and these are to be stored in a database table.. when i retrieve these data from another form in VB, i'm only able to retrieve the first product and it repeat e same product in my second textbox.
View 6 RepliesI have 2 datagrids. One to show Product information and another for Product purchase details entry. Both share the same dataset. The dataset (ds) is filled up with columns from 2 table
ProductMstrTbl : ProductID, ProductName..
ProductDetailsTbl: ProductID, PurchaseDate, Amt, BalanceQty..
DataSet(ds) : ProductID, ProductName, PurchaseDate, Amt, BalanceQty.
The problem is that: Showing from dataset or entering new records into the dataset is no problem, but am not able to save the modified dataset into DataBase. SqlCommandBuilder failed to generate the corresponding INSERT, UPDATE command as the dataset has multiple base tables.
I am looking for a free utility or way to protect my software by requiring a Product ID (Which will be created when a customer requests a paid license) to use the application after a demo version. Like most shareware apps.

View 12 RepliesI am a DCOM/Standalone Client-Server programmer who is now moving to eCommerce. I am building my first complete website for my wifes company and I have a design question for you gurus out there.
I looked at alternatives for shopping cart/product display and none of them meet my needs (e.g. ProStores). I wish to know which type of database you would use to have Many Products - Multiple Images per Product - possibly Multiple Vendors per product. I have begun a RDB using access as a prototype and I feel there was no faster method than inserting every product manually. Is there an alternative? And would you use a frame to display this data?
Would you store the images to the DB or a file reference on the host. I have begun with a file reference and truncated the path to only relate to where the file will reside on the host.

View 1 RepliesI am writing a program which detects a development board I designed which communicates with an FTDI chip. Right now my program scans any COM ports and generates a list, which the user will then choose from and connect with that device. The problem is that I want to isolate that list to only the devices which I designed. The FTDI has a unique manufacturer and device ID, but I only know how to access this data 'the old fashioned way' (i.e. through device manager).
What I would like to know how to do is determine the VID and PID of a COM port from VB, so I can dynamically get rid of any devices which do not meet the proper requirements and thus my list will only show the correct devices.

View 5 RepliesI'm looking to release an application for free with (unubtrusive) ad support, and the option to upgrade to a registered version to remove the ads. Basically we want to give the product away for free, but need some income to support costs.
What would be the best way to achieve that? I essentially just want the user to be able to type in a serial number, which is sent to a server, checked and presumably moved to a list of used serials, and then the product is activated and the ads removed.
What is the best/cheapest service to do that?
