I have problem (that seems to be obvious since I am posting here). I have an application that fetches a 64 base string out of a database and converts it, successfully to an image.
Here is the code:
Dim strImage As String = myRow("itemIcon")
Dim readmem As MemoryStream = New MemoryStream(Convert.FromBase64String(strImage))
Dim myIcon As Bitmap = New Bitmap(readmem)
readmem.Close()
Every control seems to understands the data from myIcon as being a valid bitmap, but when I import the image to an imagelist there seems to be an unreported error (or something like that) and it just doesn't display the image.
Dim tempItem As item
For Each tempItem In mainArrayList
img2.Images.Add(tempItem.ItemID, tempItem.ItemIcon)
img3.Images.Add(tempItem.ItemID, tempItem.ItemIcon)
' img3.Images.Add(imagekey, bitmap)
Next
When I do, by example "me.backgroundimage = tempItem.ItemIcon " it displays quite nicely the image, but it just doenst work with an imagelist.
Anybody an idea?

Hi,
from a quick read I can see ImageList imposes some limitations on the images, such as a maximum size of 256*256. Your example me.backgroundimage = tempItem.ItemIcon suggests you might exceed that.

That seems not likely since the images are all 32px x 32px each. It would be a blow since the data from the imagelists are to be used in a listview.
Then I need to cut away the imagelists. Is there anyway I could apply the image to a listviewitem without the imagelist?

Never mind. I solved it. It had nothing to do with the imagelist.

Hi there,
I have an if statement where i would like to link a serail code e.g b3c to a text documenbt e.g serial.text
i have already tried everything but don't seem to be able to link the document with the if statment. I have looked all over google and i really do nned some help.
my if statement is currently
if txtserial.text = ......... then
my.forms.form2.show
please help me

what txtserial supposed to be? Is user supposed to enter some serial number?
And I see you are trying to compare that value and opening the Form2.
Now I really don't get this statement.

yeh the user enters a a serial number in txtserial and if this is correct then form 2 is shown.
serial.text checks the textserial to see if the number on the text box matches what is in the text document.
Hopefully that explains it a bit better.

Well, how is it not working? Does it just never show form 2? If that is the case then the serial is never matching the value from the file. Are you sure you are grabbing the value from the file properly? If so, perhaps it's a situation like having an extra space at the end, or the user typing in lower case instead of upper case. Perhaps you need something like this:
txtserial.Text.Trim.ToUpper = strValueFromFile.Trim.ToUpper

ummmm its just not finding the value from the file.
i could do a simple if statement that would display form2.
if statement =
if txtserial.text = "hi" then
my.forms.form2.text
i really don't know how to check a txt file
All i need is a simple piece of code that consists of checking a text box aggainst a txt file.
txtserial.Text.Trim.ToUpper = strValueFromFile.Trim.ToUpper 'how woulds i use this to link for example a text file for example serail.txt
thanks

How about something like this:
Dim strFilePath As String = "C:\Serial.txt"
Dim strSerial As String = String.Empty
If System.IO.File.Exists(strFilePath) Then
strSerial = System.IO.File.ReadAllText(strFilePath)
End If
If strSerial <> String.Empty AndAlso txtSerial.Text.Trim.ToUpper = strSerial.Trim.ToUpper Then
My.Forms.Form2.Show()
End If

do i put this code under a button?? Is this the only code i need?? Will this code read and find a code e.g DC3 if i have 250+ differnet codes

You can put this code in a button click event, if that is how you want your program to work. It's up to you. This code will read all of the text in a file and compare it to what the user typed into the textbox. I was operating under the assumption that the textfile would only have one serial in it. If you have serveral serials in the text file you'll have to separate the serials and compare each one in the file, searching for a match. And how to do that will depend upon how your text document is setup. I suggest you do some more research on the subject. You could start with some of these[^] articles.

Do what?
Unless you can find a way to phrase your question so that people can understand what the hell you are talking about no one can help you!

I know what MODI is and how it works, but you're question doesn't make any sense what-so-ever.
|
|
|
|

Try and explain the question again, but this time without using any technology-related words. Specify what it is that you try to achieve, what you're observing, and what the behaviour is that you're after.

how to find the coordinates of text marked in blue after the ocr process. And if i want to copy/save the same marked area as image in some other control like picture box then how can we do that.
If i am trying to copy the area marked in blue and exporting it thru MODI.IMiSelectableImage object but its giving error "Object or With block variable not set"
When Selecting the image one red rectagle comes then only it copies the same. So how we can make visible the selection through code.
Because i have tried after selecting it manually its working fine but i want to use the same through code.
Please Help....

Hi i have a program near enough already made in vb.net but want to add a serail key program. I made it last year but don't know some of the techniques in vb.net
here is the code used
Dim xSlash As String
Dim xFileNbr As Integer
Dim xFileName As String
Private Sub Command1_Click()
Dim hole As String
xSlash = IIf(Right$(App.Path, 1) = "\", "", "\")
xFileName = App.Path & xSlash & "cookies.txt"
xNbr = FreeFile + Rnd
Open xFileName For Input As #xNbr
Do Until EOF(xNbr)
Input #xNbr, hole
If Text1.Text = hole Then
Startnot.Value = vbUnchecked
Form3.Visible = True
Me.Visible = False
Else
Label1.Caption = ("Wrong CD Key")
'B36-678-A863-7CG8F'
-
End If
Loop
Close
End Sub
Private Sub Form_Load()
xSlash = IIf(Right$(App.Path, 1) = "\", "", "\")
xFileName = App.Path & xSlash & "cookies.txt"
SetAttr xFileName, vbHidden
Dim Dontshow As Long
Dontshow = GetSetting(App.EXEName, "Options", "Dont Show Me", 1)
If Dontshow = 1 Then
Unload Me
Form3.Show
Exit Sub
End If
Startnot.Value = vbChecked
End Sub
Private Sub Startnot_Click()
SaveSetting App.EXEName, "Options", "Dont Show Me", Startnot.Value
End Sub
Public Function backup()
Dim XfileW As String
xSlash = IIf(Right$(App.Path, 1) = "\", "", "\")
XfileW = App.Path & xSlash & "checkme.txt"
xNbr = FreeFile
Open XfileW For Output As #xNbr
If Text1.Text = hole Then
Print #xNbr, "1"
Close #xNo
End Function
if anybody could translate it, that would be very helpful as i have laoready pulled out a lot of hair!!!
Many thanks
Dan

first indent your code and repost it

There is nothing overly complicated with your original code. I would strongly suggest you spend the time converting it to vb.net yourself, which will help with the vb.net learning curve.
Remember Google is YOUR friend.
You will need to use the System.IO.File namespace and some of the methods of String for example AStringVar.Length and AStringVar.SubString
If you get really stuck, you can ask us help, but NOT to rewrite the whole code for you.
Gook luck.

Thanks Steve for the reply. Umm i haven't really used System.Io.file as well as the other two. Can you explain how to use them in relation to my code???
And the reason for posting the cdoe is that people usually ask to see the code.

Posting the code was the right thing to do. Failing to put it inside 'pre' tags, so that the formatting and colourization were retained, was where you upset people. Honestly, it is so difficult to read unformatted code that I usually just skip over those posts, which might be a good thing.
