I wouldn't bother; I'd just write the app normally and if something is missing it will throw an Exception. For instance, if my app tries to use the ACE engine to query an Access or Excel file, if ACE isn't present I get an Exception explaining this.

Avoid float; try Decimal or double 1) Avoid Convert; in this case use ToString, perhaps with a format parameter 2) Avoid TextBox for numeric values; use a NumericUpDown

Just try accessing whatever it is you need to access. Nothing else matters.

Well there are 2 crude ways to do it: (if you haven't written drivers for your connectivity interfaces ;P ) 1. Enumerate all the network interfaces (non-virtual) and disable them 2. Configure a non-existent proxy server (like 0.0.0.0 port 80) for time being. After you are done with your execution reset this dummy proxy. Ensure you can backup any existent proxy settings if any.

Hi, Sorry about the delay, but better late than never I guess ... hehehe... As mentioned by smags, there are several free and commercial barcode printing solutions. Another one that you might want to look at is the one that comes with tpsystools and is available here[^] Plus you get the added benefit of getting some really cool tools with it as well. I must admit that I have not used the barcode components that come with it, but I have implemented most of the utilities/classes that come with the package. And it's free!!! :) Cheers, Glen Vlotman "You cannot code for stupidity"

See the DriveInfo class to get information about drives on your system.  Then see the DriveType property that reveals the type of drive (fixed, removable, etc). /ravi My new year resolution: 2048 x 1536 Home | Articles | My .NET bits | Freeware ravib(at)ravib(dot)com

You mean you want to pass the information from one form to the next? You can do so by passing it through the constructor or via using a property. V.

I hope this will help: Form1 frm=new Form1(); frm.Show(); TextBox textBox=frm.Controls.Find("textBox1",false)[0] as TextBox; textBox.Text = "new text";

Agree 100%. Always use the full name.

And there are web services which you can use.

He did. It's your job as a programmer to understand the classes you're using. Read the documentation on the Process class and you'll probably end up learning a lot about the Process class instead of knowing just the single little use case that someone gives you in a code sample.

Hi, I know three ways to get some information on physical devices: 1. using the DriveInfo class 2. using WMI, have a look at the WMI classes Win32_DiskDrive, Win32_LogicalDiskToPartition, Win32_PhysicalMedia, Win32_CDROMDrive; which ones you want depends on the information you need. warning: not everything may be available to regular users under Vista/Win7 without going trough the UAC dialog. 3. using Win32 functions (from kernel32.dll), which requires P/Invoke. Here is an example prototype: /// /// Gets the drive type /// /// drive name (letter colon backslash) /// /// 0 (DRIVE\_UNKNOWN) The drive type cannot be determined. /// 1 (DRIVE\_NO\_ROOT\_DIR) The root path is invalid. (no volume is mounted at the path). /// 2 (DRIVE\_REMOVABLE) The disk can be removed from the drive. /// 3 (DRIVE\_FIXED) The disk cannot be removed from the drive. /// 4 (DRIVE\_REMOTE) The drive is a remote (network) drive. /// 5 (DRIVE\_CDROM) The drive is a CD-ROM drive. /// 6 (DRIVE\_RAMDISK) The drive is a RAM disk. /// \[DllImport("kernel32.dll")\] public static extern int GetDriveType(string rootPathName); For each of these, I refer to the MSDN documentation, Google, and some experimentation. :) Luc Pattyn [Forum Guidelines] [Why QA sucks] [My Articles] Nil Volentibus Arduum Please use <PRE> tags for code snippets, they preserve indentation, and improve readability.

We use RS232 to collect raw A to D data from products when they are being tested for FDA compliance. The form, the Comm, and the file I/O are all invoked using their own thread. There is a momentary pause as the screen refreshes each position of the form while being moved, and depending on the machine, we've had problems when a user either moves a form to another part of the screen or decides to surf the internet or play solitaire because the testing is so boring. It is simple matter of resources, especially of time. When a company spends in the tens of thousands of $$ for testing, it is best to mitigate any possibility of data corruption. This is mission critical stuff in the medical device industry. The intent of my post is that a person should not prevent a user from being able to use normal interface operations such and clicking a button with a mouse or moving a form. I gave an example where a programmer could be instructed to do a little user action prevention. It was broke, so I fixed it.

ok, let me explain more when u r typing a text, if press DownArrow while holding the Shift key, a block will be generated. BLOCK in text means a selected portion of text ok? after creating a block, if u press for example uparrow or home or..... that portion of text(BLOCK) will get unselected. i dont want this. i want that block still stay selected.
