I am currently having a headache on how to solve this problem that i am facing. here is the situation: I have a combobox and a list box on the main form. The combobox will get the data from the ms access database. In the database, i have the details of a person's IC, Name and DOB say for eg on one entry I have D215311523C,SHAWN,13/04/1987 So now, my combobox on form load will show the list of dates in the database to allow the user to search base on the date itself by clicking on the selected date. So when the user clicks on the particular date say 13/04/1987, people in the database whose birthday is 13/04/1987 will be shown on the listbox.Meaning to say if i have 3 entries whose dates are the same 13/04/1987, 3 entries will appear. If there is only two entry, then two results will be shown. But now, when i do a single click on the date, one result will be shown. That is correct. But the problem is when i click on the same date again, three of the same results will be shown on the list box. that is it will display : 13/04/1987 13/04/1987 13/04/1987 which is not the case. Then it will show more duplicates of the same results if i click more times on the same date which should not be the case.

View 2 RepliesI am encountering the following issue So i have a device that sends stuff at the serial port, i then parse it and put it into an array of bytes like that:
Dim HCI_Command_Rcvd_Byte() As Byte All good till here What i wanna do is make an array and put this result every time the serial port gives me a new result, for example:
[Code]...
Basically what i wanna do is let the port parse the messages, fill in the array with the result at an empty spot in this array and then i will have a separate thread that will look in into this array in each non empty space and after it looks into the non empty space it will use or discard the info and also mark this space as empty (after it checked)
If I run into a problem or if I find that I don't fully understand a section of code I go online and search for the information I need. Which is usually quite easy.Ive made a simple chat program using the TCPlistner and TCPclient that can be found on msdn.

I just read about DataSet in VB.NET, it uses disconnected concept. My question is: if my apps has "List All" button that query data from 1 table in the database, and that table has "very very very" many rows, so my DataSet will be filled with those data and eat up memory. Can I limit the data that being put to the DataSet from that query? But I want to be able to retrieve the next data from the same query if the user want to see it?
For example:
I have 1000 rows in my database, and i query all of them. But I just want 200 rows being inserted to my DataSet, but if the user want to see rows number 201 and so on, I want to be able to retrieve the next 200 rows, and so on. So it just like cutting those data into a group of 200 rows. Can I do this with the concept of "disconnected" of the DataSet?

I normally install my application in a directory in the c: drive as the software is only used within the company.There is some simple security; the program writes a 'bat' file that gets the volume serial number this then this is used to generate a licence file. Both of these files are written in the application directory.I'm giving the program to an external client and am going to install the program in the program files directory - but I find I cannot write a file to the Windows 7 program files directory.

View 1 RepliesI have an installer class that presents a form to the user. One of the functions of the form is to browse to a file using the open file dialog. This form functions fine when used in an application but hangs when calling OpenFileDialog.ShowDialog() during an installation on a Windows7 or Vista machine (Windows XP it works as expected). I get the same rusult when 'run as administrator' and with UAC off. I also get the same results when calling SaveFileDialog.ShowDialog() in the same context. The call doesn't throw an exception but causes the form to stop responding. Any suggestions on how to get this to work correctly?
View 6 RepliesI've been doing some more experiments and have summarized the query as below: I've created the simplest application. A project with a plain form, which writes text file within its application directory. Simple as that.Supposing this was my application which I want to distribute on the world web. I've created a basic installer for this using NSIS installer. The Installer installs my application in a folder created inside Program Files. The OS is Windows7 and UAC is enabled.Now I know many people have been facing difficulties in accessing files inside the Program Files folder. My app is simply creating a plain text file, nothing more, and within its own application directory. It is giving Access Denied error. But if I right-click on the EXE and run it as Administrator, then it works ok.The only solution thats available is not to write in the application folder, and write text file in some other folder which is not protected. My question is that other programs that are installed on my system are also doing it. I have a temperature monitoring software called SpeedFan on my system, it creates log files within its app directory. All other softwares create log files within their app directories, why cant I?I just have to make a small log file for my application and Win7+UAC is not letting me do it. I don't want to write the small file in any other folder. How are the other softwares accomplishing this ?
