Hi,
My Front end is VB.net 2008
I have a form. In this form, I have a menu control, this menu control has four buttons.
On clicking the first three buttons, open the window with Show() event.
and the fourth button open the screen with ShowDialog()
Now, One by one I am clicking the button , so finally i have now four windows of this application.(Three with Show() and one with ShowDialog())
Right?
Now I am minimizing all the windows with the help of Window + D Button.
After this, If I use the keyboard(Alt+ Tab) keys. This is opening the showDialog window on top because , Show dialog's TopMost = True.
Now I come back to my problem. That's why I cannot use the show/Showdialog overloaded menthod to pass the Me/form-id
Again, I use the keyboard(Alt+ Tab) keys, to minimized all windows. In the taskbar and Startmenu properties , I have selected the Group Similar Taskbar buttons
This resulted in the heap of my application windows, one on the other.
I hope you have understood this point. By doing this , same kind of windows lie one on the other.
Now i click on one of my application window , and If I click the window other then the Show Dialog opened Window, this is not bringing the show dialog window to topMost.
Note:- There is no parent child window requirement. That's why I can't use the Show/Show Dialog overloaded method to pass the Me/Form-id
This is the problem.
Please let me know if you still face any problem in understanding the question.

So far, i have gotten the hang of using VB 2008, and managed to read and write to one serial port. Now, I need to open two different ports simultaneously. One port needs to be read and write and the other just to read and trigger and event when it fills a statement. My questions are,
1. Can I open multiple ports by using the same method as oepning a single port?
2. When I receive data from the two ports, can I invoke two different receive events?
Much help would be appreciated on this. Thanks in advance.

Thanks for the quick reply.
I'll test it out some more before asking for more help on this. Hopefully, there won't be too much problems.

I am doing a hardware based project and planning to establish communication with the computer using Serial Port RS-232 using an interface IC MAX 232.
I am doing my project VB.Net 2008 and have no prior experence with the same. My computer doesnot posses a serial port so I am using USB to Serial convertor. My PC has COM3 port. Please can someone help me with the serial programming as MSDN was of no help. Also the binding navigator command is unable to calculate the maximum number of records present when the form is opened.

If you think that is the case, then you are using the wrong search term. I found loads of Serial/RS232 tutorials with VB on MSDN.
Try altering your search!

Hi,
You want the SerialPort class.

I meant MSDN was of no help because it confused me.
From where exactly should I start.
I have no experence in this issue and even a begginer in VB.Net.
Do i need to get some dll or I can directly start as shown in MSDN.
I am using Visual Studio 2008.
Thank You.

Hi,
if you are a beginner in .NET or in one of its languages, then a serial port application is not a good start. You should get well acquainted with the platform before you start tackling a serial communication, since that is, although not very complex, well hard to debug and get it right, since it takes some doing to figure out which end is or isn't doing what.
Once you know .NET and either C# or VB.NET you will need the SerialPort class. There are some good articles on CodeProject about serial communication.
The port being USB connected is rather irrelevant, assuming you install the driver that came with the USB-to-serial cable. The driver turns the port into a regular serial port, so it shows up
in all serial port enumerations, and most/all serial apps can use it, whether
HyperTerminal or some .NET based app using SerialPort class.
The app never is aware the USB-based serial port is connected in a different manner,
all the nasty details are hidden by Windows and the device drivers.

Give a solution for what? We're not going to do your work for you. You need to do the work, and when you hit an actual stumbling block, perhaps we can help.

The fact remains that you did not ask any specific questions, so it's not clear what answer you are expecting.
For reading the text file, you may want something like System.IO.File.ReadAllLines.
That gives you an array of strings. It should be easy to move through the array, and parse out each string to obtain the first 'column', although you didn't specify how they are delimited.
Then you'll need some ado.net to query the database, and again some System.IO.File related classes to write out to the text files.
You didn't provide much detail, so I can't provide anything more specific.

There are several ways to read and write the data to file. Search web and you will find lots of samples.

Honestly, 2 - 4 don't make sense to me. Maybe it's a lack of caffeine today on my part.
Post your code so we can see what you're attempting to do.

Try Crystal Reports. The Express Editions of Visual Studio don't come with the reporting goodies that the full versions do.

Thanks for the input. Do i need t get (buy) Crystal Reports?
I had tried using a report utility available in Sharp Develop 2.2, any idea what is that all about? I tried googeling for it did not get almost any thing on it...

I'm sure that this is just a typo;
cmd = New OleDbCommand("select ITEM_NBR,NPR_DC_NBR,NPR_NBR from E_Ensemb where ITEM_NBR =" + a, cn)
Are you getting an error? If not, does the query return results if you run it manually?
