Hmmm that use the Imaging class
I have seen that used in medical applications I believe,
Maybe I will try a different approach. You would think that Microsoft would of made saving an image a whole lot easier wouln't you?

I am using the this sub and on the following line of code I get an error
pixColor = myBitmap.GetPixel(x, y)
the error states "An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in System.Drawing.dll
Additional information: Parameter must be positive and < Width."
Would anyone know why?
Private Sub my_capture(ctrl As Control, fileName As String)
Dim bounds As Rectangle = ctrl.Bounds
Dim pt As Point = ctrl.PointToScreen(bounds.Location)
Dim myBitmap As New Bitmap(bounds.Width, bounds.Height)
Dim BW_Bitmap As New Bitmap(bounds.Width, bounds.Height)
Dim x As Integer
Dim y As Integer
Dim pixColor As Color
Dim luma As Integer
Using m_g As Graphics = Graphics.FromImage(myBitmap)
m_g.CopyFromScreen(New Point(pt.X - ctrl.Location.X, pt.Y - ctrl.Location.Y), Point.Empty, bounds.Size)
m_g.Dispose()
End Using
For y = 0 To BW_Bitmap.Height
For x = 0 To BW_Bitmap.Width
pixColor = myBitmap.GetPixel(x, y)
luma = CInt(pixColor.R * 0.3 + pixColor.G * 0.59 + pixColor.B * 0.11)
BW_Bitmap.SetPixel(x, y, Color.FromArgb(luma, luma, luma))
Next
Next
BW_Bitmap.Save(fileName, ImageFormat.Png)
BW_Bitmap.Dispose()
myBitmap.Dispose()
End Sub

..from 0 to 640, is 641 steps, not 640. That's one more step than there is pixels, causing it to go out of range.

Considering you haven't told us anything about what you want to do and which flavor of VB you're using, it's pretty much impossible to tell you anything useful.

We have couple of projects (1 win forms and 1 web form) written in VB.Net. We would like to get those converted into C#. We would be using VS 2012 Professional for BUILD. I am already googling for such tools but would also like to take community's opinion/recommendation on any such highly recommended tools with highest precision/accuracy in converting code from VB.Net to C#. I am good with free and paid tools. Your pointers/suggestions will be highly appreciated.
Thanks in advance.

From what I've seen, most tools work well. But, if the project works, why are you converting it? It is is worthwhile, why not take the time to convert by hand?
The syntax isn't that different, and it is an opportunity to learn.

|

All our projects are written in C#. Hence wanted to convert these 2 apps to C#.

I have some code that moves data from an Access database into an Excel spreadsheet. I know that there are easier ways of doing this, but for my particular needs I have to have it moved this way.
The code goes through a query in Access and moves data into the spreadsheet with a loop. That part works just fine.
The problem is that I have to format the spreadsheet with this code. All of the different categories of data will be formatted differently. The piece I am looking at now is called "TheTO."
The code I have moves the data and then goes back and formats cells based on their content. It looks for the words in the cells to do this. The problem is that I will have to repeat this code for about 40 different phrases. That seems excessive to me. Also, if any of those phrases change at all, the code won't work.
I want to have the formatting happen during the loop. However, I don't know how to do that.
Here is the code. I am including one block of the code that is formatting the cells. There would be many, many more because the C.Value will be different every time.
TheTO = rs!to
oSheet.Cells(2, 1).Value = TheTO
TheSTOname = rs!STO
oSheet.Cells(3, 1).Value = TheSTOname
TheStaffName = rs!TeamName
oSheet.Cells(3, 2).Value = TheStaffName
theActDesc = rs!ActDesc
oSheet.Cells(3, 3).Value = theActDesc
rs.MoveNext
Do Until rs.EOF
If rs!to = TheTO Then
If rs!STO = TheSTOname Then
If TheStaffName = rs!TeamName Then
If theActDesc = rs!ActDesc Then
rs.MoveNext
Else
theRow = theRow + 1
oSheet.Cells(theRow, 3).Value = rs!ActDesc
rs.MoveNext
End If
Else
'theRow = theRow + 1
oSheet.Cells(theRow, 2).Value = rs!TeamName
TheStaffName = rs!TeamName
rs.MoveNext
End If
Else
theRow = theRow + 1
oSheet.Cells(theRow, 1).Value = rs!STO
TheSTOname = rs!STO
TheStaffName = ""
rs.MoveNext
End If
Else
theRow = theRow + 1
oSheet.Cells(theRow, 1).Value = rs!to
TheTO = rs!to
rs.MoveNext
End If
skip:
Loop
iNumCols = IIf(w > 0, w, iNumCols)
'Format the header row as bold
With oSheet.Range("a1").Resize(1, iNumCols)
.Font.Bold = True
'Size the columns
.Columns("A:A").ColumnWidth = 40
.Columns("B:B").ColumnWidth = 22
.Columns("C:C").ColumnWidth = 73.44
End With
oSheet.Range("A:A").NumberFormat = "dd-mmm-yy "
With oSheet.Range("A1:" & Chr(iNumCols + 64) & rs.RecordCount + 1)
For Each C In oSheet.Range("A1:" & Chr(iNumCols + 64) & rs.RecordCount + 1).Cells
If C.Value = "First TO" Then
With C
.Font.Name = "Arial"
.Font.Bold = True
.Font.Size = 12
.Interior.ColorIndex = 15
.Borders(xlEdgeTop).LineStyle = xlContinuous
.Borders(xlEdgeTop).Weight = xlThin
.Borders(xlEdgeTop).ColorIndex = xlAutomatic
.Borders(xlEdgeBottom).LineStyle = xlContinuous
.Borders(xlEdgeBottom).Weight = xlThin
.Borders(xlEdgeBottom).ColorIndex = xlAutomatic
.Borders(xlEdgeRight).LineStyle = xlContinuous
.Borders(xlEdgeRight).Weight = xlThin
.Borders(xlEdgeRight).ColorIndex = xlAutomatic
.Borders(xlEdgeLeft).LineStyle = xlContinuous
.Borders(xlEdgeLeft).Weight = xlThin
.Borders(xlEdgeLeft).ColorIndex = xlAutomatic
.Borders(xlInsideVertical).LineStyle = xlContinuous
.Borders(xlInsideVertical).Weight = xlThin
.Borders(xlInsideVertical).ColorIndex = xlAutomatic
.Borders(xlInsideHorizontal).LineStyle = xlContinuous
.Borders(xlInsideHorizontal).Weight = xlThin
.Borders(xlInsideHorizontal).ColorIndex = xlAutomatic
End With
End If
Next C
Thank you, in advance, for any help you can give me!!!!! (I am very new to coding!!)

You don't need to loop through the Access data to copy it to Excel line by line - Excel has a CopyFromRecordset method[^] which can be used to transfer it in one go.

The loop is so that the items are listed correctly and do not repeat like they do in the query in Access. I don't know any way to make it look the way it needs to look without the loop.
Any ideas on the formatting?

Hi all,
I have been working on a script to do what the subject line says but I'm really not getting anywhere. I feel as though I'm almost there, but I just can't figure out the last part.
My script is as follows:
Option Explicit
Dim strProjectsFolder, strProjectNumber, strCostingsPath, strProjectsLTDGroup
strProjectsFolder = "\\ac1fpcov01.za.if.atcsg.net\Business\Delegation IT\Projects\"
strProjectNumber = InputBox("Please enter the new Project Number", "Project Number")
strCostingsPath = strProjectsFolder & strProjectNumber & "\02. Costing"
strProjectsLTDGroup = "AC1-LS-Finance SSC"
SetPermissions
Function SetPermissions()
Dim intRunError, objShell, objFSO
Set objShell = CreateObject("Wscript.Shell")
Set objFSO = CreateObject("Scripting.FileSystemObject")
If objFSO.FolderExists(strCostingsPath) Then
WScript.Echo "You're changing the permissions on " & strCostingsPath
intRunError = objShell.Run ("%COMSPEC% /c Echo Y| ICACLS.EXE " & strCostingsPath & " /inheritance:d /remove:g AC1-LS-Finance SSC:(OI)(CI) ", 2, True)
If intRunError <> 0 Then
Wscript.Echo "Error removing inheritance from " & strCostingsPath
End If
Else
WScript.Echo "Error: Project Folder " & strProjectNumber & " does not exist."
End If
End Function
WScript.Quit
I've REMd some lines to simplify while I debug, so I'm currently focusing on the removal of inheritance. I figured if I got that bit right I could move onto the removal of permissions, either in a second IF statement or in the same command line.
But basically, what the script is doing is:
1. Ask the user for the Project number (e.g. P33333)
2. Set variables for the file / folder location based on the project folder on the server
3. Check that the project folder exists, and show a message with the subfolder on which the permissions are being changed.
4. Run the ICACLS command with the /inheritance /T switch to disable inheritance on the project subfolder and all subfolders and files.
5. I've included inRunError to capture any errors, and added another IF statement to show which part of the script is showing the error (only the inheritance section is active at the moment).
6. Finally, an Error trap in case the project folder was entered incorrectly.
Run the script, and all I get is the inRunError that the inheritance command isn't working.
I've taken the exact same command and entered it into a bat file and it works perfectly fine. But in a script it fails every time. I've tried taking all the variables out and working with a skeleton script and still nothing.
So it leads me to believe that I'm either trying to do something with the command that isn't possible, or vbscript just doesn't like me.
Any help would be greatly appreciated.
Thanks
Chris
PS. I should also add, clearly the folder is on a network location. My user account does already have full control permissions over the folder.
It is also an AD security group that I am changing the permissions of in the second part of the script, again it works as-is in a bat file, but not in the script.

I see you are feeding the stdin of the command-line using the echo command. Two things I would try;
- Try feeding stdin by feeding it from a textfile; one can write stdout to file by routing it (e.g., dir /s >folders.txt), but one can also route stdin. (format <input.txt).
<li>Instead of executing the command with its switches, generate a single batch-file that holds that command as a text, execute it, and delete it.

Quote: I have a project that requires more than 1 Barcode reader in the same pc How to know where the shot had come from the barcode reader., please help me sample coding in vb.net
|
|
|
|
|
This will only be possible if you have an SDK for the sepicific type of barcode reader, and the barcode reader works via that SDK only (i.e. does not emulate a keyboard). You have to read the documentation for the barcode reader.
|
|
|
|
|
|
Some barcode readers are very basic, all they do is fill in whatever control has focus. Meaning, whatever textbox has focus when you scan the barcode it will just dump the string right into the textbox. No logic or complexity to it. So, it will all depend on the barcode reader you have.
There are only 10 types of people in the world, those who understand binary and those who don't.

Please I'm using vb.net 2013 and I have a textbox named txtRecipients
Now i want to check for the following:
1. The phone no. should always start with 233 followed by any digit other than zero like: 233201245685
2. Multiple phone numbers should be separated by a comma, like 233201245685, and the comma replaced automatically before the start of another phone number in the same format. So if two phone numbers are entered they should be like this:
233201245685,233547345696
I did something like this in the leave event. Is there any better way to do this as the comma is not getting replaced at a specific position. I used both the remove and replaced functions, but that did not work. Thanks in advance
<pre lang="vb">
Dim str1 As String = Mid(Me.txtRecipients.Text, 1, 1)
Dim str2 As String = Mid(Me.txtRecipients.Text, 2, 1)
Dim str3 As String = Mid(Me.txtRecipients.Text, 3, 1)
Dim str4 As String = Mid(Me.txtRecipients.Text, 4, 1)
Dim str13 As String = Mid(Me.txtRecipients.Text, 13, 1)
If str1.Trim <> 2 Then
Me.txtRecipients.Focus()
MsgBox(The first digit must be 2)
Exit Sub
End If
If str2.Trim <> 3 Then
Me.txtRecipients.Focus()
MsgBox(The second digit must be 3)
Exit Sub
End If
If str3.Trim <> 3 Then
Me.txtRecipients.Focus()
MsgBox(The third digit must be 3)
Exit Sub
End If
If str4 = 0 Then
Me.txtRecipients.Text.Replace(0, String.Empty)
Me.txtRecipients.Focus()
MsgBox(Phone No. must not start with 0. Format e.g. 233243404804)
Exit Sub
End If
If str13 <> "," Then
' Me.txtRecipients.Text.Replace(str13, ",")
Me.txtRecipients.Focus()
MsgBox(Phone No. must not start with 0. Format e.g. 233243404804)
Exit Sub
End If
</pre>

I will use first a split on the comma(Me.txtRecipients.Text.split(",") and walk throu the array. Check the first tree chars in 1 time. string.substring()
check the others with like (string like "233#####")

I have this
textbox that users enter their names, but
I realized that they enter their names by entering so many spaces. I used the
replace function but it does not work well. Is there anyway to prevent this at
keypress, when the user tries to press the space bar more than once? Thank you,
all.

Member 11078565 wrote: I used the

What does that mean? Did you use it correctly?
yourString = yourString.Replace(" ", " ")
or with Regular Expressions:
yourString = System.Text.RegularExpressions.Regex.Replace(yourString,"\\s+"," ")
|
|
|
|

Trap the keydown/up event, inspect the current and previous characters in the string, if they are both a space then deal with it in the event.

I am making a little app and I am stuck. I have a multilined textbox and I would like a button to take the text and reverse the line order. So if the text was numbered each line as 1->9, pressing the button will reorder the lines so they are 9->1.
