I'm still new in VB.net development environment, i've few of the question may need the advice from you guys to see whether i'm in the right track for the development as below condition:Basically my program wrote from this logics:
Condition:
2 log files available in C drive that is C:/BSKYB/Prod.txt
and C:/BSKYB_CWE/many of log files in .txt format
Program Flow:
Step 1: The program will read the last sentence Hexa number from the file "Prod.txt"
Step 2: Once the program detecting the keyword like example "abcde" it will go to another folder which is descript in C:/BSKYB_CWE to look at which text files contains the keyword "abcde"
Step 3: this step will capture the whole line the text info like example 1111 abcde
if in this case, once the abcde detected what is the command i should apply to capture the key word 1111 ?
This is the problem i have encounter right now, i doesn't know how is actually can apply the right method to read the whole text line once the key word is detected
Public Class Form1
' Const ConstBSKYB = "C:BSKYB_CWE.txt "
'Const ConstBSKYBP = "C:BSKYBProd.txt"[code].....
I would like to be able to open up notepad/word/etc and type in a keyword/password and have my program use that text.
The idea behind this is for our CMS application. Want to be able to capture the customer numbers as they are put in and have my program pull all the customer products etc. I am currently able to capture the keyboard text just not how to filter it as it is being typed.
I want to search a text file (*.txt extension) for a certain keyword or a part of it. And then let the found item be displayed in a listbox or something else. Now the more difficult part, how can I display the word in front of that found word ?
Example: I search for VBFORUMS in a file called test.txt I find this: VBFORUMS but in front of that is this: IDS_IDS_TXT_008912VBFORUMS
How can I then display the IDS_IDS_TXT_008912 on a label ?
I am working with an image tagger system. I am done reading the file's properties. Then when I go to code for keywords.. an error exist saying that Retrieving the COM class factory for component with CLSID {58968145-CF05-4341-995F-2EE093F6ABA3} failed due to the following error: 80040154.

Visual Basic has a function that allows a video from a webcam to be saved as .AVI file which inherently is too large for data transfer over the internet. I would like to know if there is a function that allows the video to be saved as a .WMV, or a .FLV file so its smaller and allowed to be transfered over the net. Here is a snippet of the code i am using
I have written a code from which using a web camera one can record a video and save it onto the HDD but now according to a client requirement he needs to play that video and capture still images from the video and save it onto a picture box's and here is where i am having issues.
1)when i use windows media player to play the recorded video i don how to capture the image from the video by triggering an event
2) also i need to know if i can play the video on picturebox tool(i tried using the winmm.lib and Mci but it din work out for me)
I am trying to capture URLs in HTML file which appears like
<a[string]href[space(s) or nothing]=[space(s) or nothing]["][url]["][string]>
I found this code but it does not work well.
Imports System.Text.RegularExpressions Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim rx As New Regex("[<]a[s][wW]*[href=](?<word>S*)[sWw]*[>]", _ RegexOptions.Compiled Or RegexOptions.IgnoreCase) Dim text As String = "<a href=http:// name=as>" Dim matches As MatchCollection = rx.Matches(text) For Each m As Match In matches MsgBox(m.Groups("word").Value) Next End Sub End Class
I am trying to update some local access databases from a web database. When I am accessing the web page, I want the user to select a folder on the local hard drive where the DB's reside that will be updated by the program. I actually have been using the File Upload control to do this as it has allowed me to check the file extensions on the local DB's their file size and other misc. items. [code]...
Does anyone know how to capture (Record) the Windows desktop and save it as a '.avi' or '.mpg' file. This functionality can be done using screen capture / presentation programs like SnagIT:[URL]..I have found many examples showing how to capture from a webcam using the 'avicap32.dll' DLL file but these dont help with this problem.
If you are asking why i dont just use SnagIT its because the interface is overly complex and building my own version would allow me to intergrate it into my existing programs.
So I am hacking together an app which listens to traffic using SharpPcap library, it reconstructs the packets from sessions using the code from TpcRcon.
Listening and reconstructing part work on their own . What I want is on each packet arrival main window gets an event so it can display the packet , and when session is reconstructed display a complete packet (I am interested in HTTP ones) . -That is where it breaks with weird symptoms: for example right now it does not stop on invoking stop listening method - the sharppcap library function hangs there forever waiting on this line of code : m_pcapThreadEvent.WaitOne();//wait for the 'stopped' signal from thread
I also had it not working and crashing in sharppcap function because I had omitted one parameter in form delegate- which makes no sense, because form delegate does not deal with packet capture at all and only reacts on "New Packet" event from my "Listener" class (which is only there to notify main form)
My app starts as module main instancing class "Listener". MainForm has it registered as friend with event and handles even "New Packet"
Main Form: Private Sub uiListenStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btListenStart.Click aLogger.AddMessage("Started Listening")
How can i capture my console real time output and store the information in a log file?
i know that i can write in the file when i write in the console window, there's got to be a better way... how can i capture the console's output stream?
I found that Console.OpenStandardOutput is a stream, but i can't read from it
Dim r As New StreamReader(Console.OpenStandardOutput) MsgBox(r.ReadToEnd) r.Close() r = Nothing
Dim VideoSize As Size = New Size(My.Computer.Screen.Bounds.Width, My.Computer.Screen.Bounds.Height) Dim PIC As New Bitmap(My.Computer.Screen.Bounds.Width, My.Computer.Screen.Bounds.Height) Dim image As System.Drawing.Graphics = System.Drawing.Graphics.FromImage(PIC)

How do I include the cursor with this and save all the screenshots as one video file?instead of saving as 1000 pics?
Protected Sub Menu1_MenuItemClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.MenuEventArgs) Handles Menu1.MenuItemClick End Sub
In VB.net, we have the Handles keyword, I'm wondering if C# has anything comparable. Or do you have to manually wire all the methods to each control's event (in ASP.NET especially)?
Possible Duplicate:Default value for generics k so while translating some code from c# to vb, i came across the default keyword, and I'm simply replacing it to nothing.
In my current project everyone names variables and methods after what they are and what they do. This is good for quickly understanding the code, but with a lot of long varible names comes some headaches, such as when copying a dataset to an entity/object. So, while you understand the code, the readability still takes a blow.
veryLongVariableName.Id = datasetVeryLongVariableName.Id veryLongVariablename.Something = datasetVeryLongVariableName.Something etc.
Using VB.NET's With keyword can help.
With veryLongVariableName .Id = datasetVeryLongVariableName.Id .Something = datasetVeryLongVariableName.Something End With
Now, my question, is there any way of using With, or something similar, but for several variables at the same time? Something like:
With veryLongVariableName As a, datasetVeryLongVariableName as b a.Id = b.Id a.Something = b.Something End With
I'm all for descriptive naming conventions, but they do tend to clutter things. Especially in VB!
I m trying to create a software in vb.net for some genealogists to trace their ancestors History, the users will search for the document in 3 ways
1. reference number from a combo box. 2. By the title of the document. 3. by inserting a keyword from the documents abstract..
i have already loaded the picture. i hav put all in one note pad my reference no., on next line i put my abstract and on the third line i put my path where the document is located.in coding i put all in different array.... making the program read all one by one line wise.i want to make search thru the keyword... means wen user inserts a key word in the textbox the program read all my abstract and then in a drop down it should display the documents that match the keyword.
Its work well in windows 7 but when i run project in windows xp its says i must use New keyword but when i use New its gives error at regkey.GetValueNames and RegistryKey = Registry.LocalMachine and regBaseKey.OpenSubKey("SOFTWAREMyApp", FalseImports Microsoft.Win32[code]...
I have to serialize/deserialize a class into a JSON string/and return. The JSON Strinig must contain the "error" string (like: {error:"something strange occoured", id:23, result:"xxxxx"}), which specifies the occoured error.
I use the Call keyword when calling subs in VB/VBA. I know it's optional, but is it better to use it or leave it off? I've always thought it was more explicit, but maybe it's just noise. Also, I read this on another forum: Using the Call keyword is faster because it knows that it is not going to return any values, so it doesn't need to set up any stackspace to make room for the return value.
First off let me say that I am essentially new to VB.NET, i.e; still learning. Also, I hope that this is the right place to post this question. In a Project I have a Class module defined as:
Public Class Def Public Id As String Public Meaning As String
I have to inherit some legacy code in company, which is written in Visual Basic.NET 7.0 (Visual Studio.NET 2002). I don't have much experiences in VB.NET, and this line of code gets me in trouble:
Public Class Global : Inherits System.Web.HttpApplication
Visual Studio gave this error: Error 31Keyword is not valid as an identifier.C:Documents and SettingsAdministratorDesktopPOManWebApplication1Global.asax.vb414C:...POMan
But when I want to use it in the Function, it gives error ("..are not valid within..."). Are there any keyword to make this in the Function or there aren't? [Code]
I generally use to organize codes below lines;#Region "Comments.."#End RegionBut when I want to use it in the Function, it gives error ("..are not valid within...").
