Creating a Sudoku generator is OK, and it is a great thing, but do not try to solve them by using computers, use your brain.

i dislike solving programs and i solve sudokus by hand frequently.

I actually find the challenge of designing algorithms to solve such puzzles is much greater than doing it by hand, especially if you apply AI concepts and use tools such as Prolog.

I've made a small code for free drawing in a pictureBox. With that, i can draw when i click-n-hold left mouse-button, release the mouse and draw anothers (without myPenWidth). But if i define myPen with the myPenWidth(if no, it's always 1 by default), there always a error "OutOfMemory" to be made when "i release my first mousedown and mousemove, and mousedown again".
Why's it happens??
This is my code:
Private Sub PictureBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseDown<br />
If e.Button = MouseButtons.Left Then<br />
mousePath.StartFigure()<br />
End If<br />
End Sub<br />
<br />
Private Sub PictureBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseMove<br />
If e.Button = MouseButtons.Left Then<br />
PictureBox1.Image = myImg<br />
Dim g As Graphics = Graphics.FromImage(PictureBox1.Image)<br />
Dim myPen As Pen = New Pen(Color.Blue, myPenWidth) <br />
mousePath.AddLine(e.X, e.Y, e.X, e.Y)<br />
g.DrawPath(myPen, mousePath)<br />
End If<br />
<br />
End Sub
|
|
|
|
|
You're not Diposing your Pen and Graphics objects after you're done using them in your MouseMove event handler. If you skip this step, you'll quite easily run the system out of GDI resources and/or system handles, causing the "Out of Memory" Exception.
.
.
.
Dim g As Graphics = Graphics.FromImage(PictureBox1.Image)
Dim myPen As Pen = New Pen(Color.Blue, myPenWidth)
mousePath.AddLine(e.X, e.Y, e.X, e.Y)
g.DrawPath(myPen, mousePath)
myPen.Dispose()
g.Dispose()
.
.
But, since you'll using this method constantly, you might want to put creating/destroying the Pen objject outside the MouseMove handler. This way you won't be creating a new pen every time the mouse moves at least one pixel!

You can use mousePath.AddEllipse instead of mousePath.AddLine
Private mousePath As New System.Drawing.Drawing2D.GraphicsPath<br />
Dim myPenWidth As Integer = 12<br />
<br />
Private Sub PictureBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseDown<br />
If e.Button = Windows.Forms.MouseButtons.Left Then<br />
mousePath.StartFigure()<br />
End If<br />
End Sub<br />
<br />
Private Sub PictureBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseMove<br />
If e.Button = Windows.Forms.MouseButtons.Left Then<br />
Dim g As Graphics = Graphics.FromImage(PictureBox1.Image)<br />
Dim myPen As Pen = New Pen(Color.Blue, myPenWidth)<br />
PictureBox1.Image = myImage<br />
mousePath.AddEllipse(e.X, e.Y, myPenWidth, myPenWidth)<br />
g.DrawPath(myPen, mousePath)<br />
End If<br />
End Sub

You only need to start the figure the first time it is clicked as it is already started after this
This will remove the out of memory error but make it so that the next drawn line joins to the last one automatically which you'll have to look at
Private Sub PictureBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseDown
If e.Button = MouseButtons.Left Then
If MousePath.PointCount = 0 Then
MousePath.StartFigure()
End If
End If
End Sub

I need to have a user select an item from a combo box and I need to use that text. I have tried combobox.selecteditem, .selectedvalue, .selectedtext and none of these seem to work. Please help. Thanks in advance.
Also, the text originally comes from a database.
|
|
|
|
|
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged<br />
Dim myText As String<br />
myText = ComboBox1.SelectedItem.ToString<br />
End Sub

Hi Friend,
Sorry I don't know ur name.
First of all I would like to know which database u r using and whether u r retrieving data from the database or inserting the data into the database.
If u r firing a SQL query then I think this will b helpful to u :
strsql = "SELECT * FROM Emp WHERE Emp_Name='" & Combo1 & "'"
This query displays all the records from the table named 'Emp' according to the list item selected from the combobox named 'combo1'. 'strsql' is a string holding the query.
Success is not a Destination,
... But a Journey !!

Try restructuring the query...
select * From MultipleChoice AS MC<br />
JOIN MultipleChoiceAnswer AS MCA ON MC.multipleChoiceID = MCA.multipleChoiceID<br />
JOIN Level AS L<br />
ON MC.levelID = L.levelID<br />

Set FormBorderStyle property to None
Set the BackgroundImage property to the image you want to use
Now set the TransparencyKey property to the background color of the image.
Run you app
Note: When I tried to do this by using VB.Net 2003 it didn?t work. Solution to this problem is reseting the screen to use color values that are 24 bits or less. In Vb.Net 2005, it works fine.
If the background color of the image appears in your image too, you can see holes in your image, therefore, do not use a common color as the background color of the image.

i've also noticed that not all video cards will make the backgronud color transparent, so be aware that someone running your app could still see the original shape of the form

Hi Guys,
Well I'm totally stumped. I've got a bit of vbscript code that tries to find a particular process running on a machine (Windows NT). If the process exists I want the text ("I am running...") displayed. If it doesn't exist then I want the text ("I am not running") displayed.
Just some background on the OS. Its Win NT 4 service pack 6 and i reinstalled WMI Core 1.5
On win xp, win 2k and win 2k3 the script below works fine. However on windows nt where this will reside on it fails giving me an error 80041001 which I belive is a "Call failed" error.
Can anyone shed some light on why this would be happening on NT in particular? Thanks in advance

Dim strComputer, strProcess
strComputer = "."

& "{impersonationLevel=impersonate}! \\" _
& strComputer & "\root\cimv2")
Set colProcess = objWMIService.ExecQuery _
("Select * from Win32_Process")
For Each objProcess in colProcess
do while objProcess.name = "Someprocess.exe"
strProcess = objProcess.name
'objProcess.Name
'If objProcess.name = "Someprocess.exe" then
Response.Write ("I am running...")
'Else
'End If
Exit Do
Loop
Next
If strProcess = "" then
Response.Write ("I am NOT running")
End If
