• DanO84 generating random letters

  What is the code for generating random letters either uppercase or lowercase in VB.NET You can use the Random class for that. Here's an example: Dim rand As New Random Dim letter As String letter = ChrW(rand.Next(Asc("A"), Asc("Z") + 1)) The Random.Next method takes 2 parameters, minValue and maxValue. Since these parameters are integers you need to use Asc to get the code of characters A and Z. + 1 is needed because maxValue is exclusive and without + 1 the Z letter will never be generated. The return of Next is also an integer so you need to convert it to a letter using ChrW function. ...Show All

• paso string matching

  hi all i m working on string matching pattern. can any one suggest me that how can i make different pattern for string matching. gorla, This example looks for parts of a string surrounded by double quotes and replaces occurrences of / with within those parts. The rest of the string also contains / so you can see that the code doesn't replace those instances. When you click the Replace button, the program uses Regex.Matches to get a collection of matches for the pattern "[^"]*". This pattern matches a quote, followed by any number of non-quotes, followed by a quote. For each match, the code adds the part of the input string between this match and the previous one and then the matched text with the a ...Show All

• David N.4117 DeviceIOControl and SCSI_PASS_THROUGH_DIRECT

  Hi, I'm trying to get data from a SCSI Inquiry command in VB. I'm using DeviceIOControl with SCSI_PASS_THROUGH_DIRECT - the call goes through OK and DeviceIOControl returns 0, but I can't seem to get the expected data back - retBytes just contains 7 bytes of seemingly (but probably not) random data: (40, 4, 20, 0 , 40, 4, 20). Changing scsi.dataIn to 0 gets me 255 bytes of data, but not the data I should be getting. Any help would be greatly appreciated. Here's what I'm doing. offset as Byte is ignored for now, and fileHandle is a valid handle to \\.\F:.

• Frank2808 insert snippet with a shortcut key

It's so inconvenient for me to insert a code snippet every time according to the following steps: 1. right click on my VB codes 2. click the "Insert Snippet..." menu item from the context menu 3. find and select the folder of the snippet I would like to use 4. find the snippet I would like to use from the selected folder The above 4 steps is too long to me. What I want is a single shortcut key for each insertion action. I considered to record a macro for this. However, I found out that I could not pop up the context menu for the "Insert Snippet..." menu item once I have started marco recording. How can I insert my code snippet in a faster way ...Show All
