substring(startposition,length)
so when startingpointer is 135 and pointer is 145 you will get a string of 145 length
if you only want the 12 characters substract startingpointer from pointer before using it
hope this helps
If my help was helpfull let me know, if not let me know why.
The only way we learn is by making mistakes.

By default, a textbox's default MaxLength value is set to "32767" characters long.
Since the field type for the MaxLength property is Int32, the highest value that you could set it to would be "2147483647".
Hope this helps,
Mitch

Hi everybody
I have a collection of word document which has got lots of Embedded image object inside it.
now what i have to do is read each word document and save out each embedded images to my hard drive ?
how do i do this without using clipboard method ?
Using the following code :
Dim word_doc As Microsoft.Office.Interop.Word.Document
word_doc = word_app.Documents.Open(FileName:="E:\testing.doc", ConfirmConversions:=False, ReadOnly:=True, AddToRecentFiles:=False, Format:=Microsoft.Office.Interop.Word.WdOpenFormat.wdOpenFormatAuto)
' Delete InlineShapes.
With word_doc.InlineShapes
Do While .Count > 0
.Item(1).Delete()
Loop
End With
i can find any inline objects and delete it . but what i want is not to delete but to save out to the hard drive ?
Any idea ?
regards
suis

Hello,
Am developing a multi-threaded application.
I have a time consuming task that is to save all the data to xml. This takes time so I am doing it in a thread. However, when the thread is started, I would like to open up a new form rather than have the user wait for the save to finish, then open a new form.
However, the new form never opens until the work is completed and the UI is not responding.
In the output window i can see that the threads are existed everytime they go to the sub procedure to save the XML. I think that all the work has to be done in the thread procedure and cannot call other procedures, but not sure about this
Many thanks for your help.
<br />
'Form load event<br />
public sub FormLoad<br />
dim threadSaveXML as new System.Threading(Addressof SaveXML)<br />
threadSaveXML.Start()<br />
<br />
'Open the new form while the data is still currently being saved. Do not wait for the data to be saved first<br />
Dim objOrders as new frmOrders()<br />
objOrders.Show()<br />
<br />
'Hide the current form so the process can still take place in the background.<br />
me.hide()<br />
End Sub<br />
<br />
<br />
'Calls the sub procedures to save the actual data to xml.<br />
private sub SaveXML()<br />
SaveBeverages()<br />
SaveMainCourse()<br />
etc.....<br />
End Sub<br />
<br />
private sub SaveBeverages()<br />
'saves to xml<br />
end sub<br />
<br />
private sub SaveMainCourse()<br />
'Saves to xml<br />
end sub<br />

Try this code instead:
dim threadSaveXML as new System.Threading.Thread(New ThreadStart(Addressof SaveXML))
threadSaveXML.Start()
Hope it helps !

Sounds like your printer settings are wrong - the non printable margins incorrect?
|
|
|
|

Printers will return reports in slightly different formats even though they may be encoded to use A4.
This is just a fact of IT life.
The only way around this is:
.1)Ensure that the you have the correct drivers for the dot matrix.
.2)Design the report for the printer it is being printed on.
.3)Resign yourself to the fact there really is no way around this sort of problem other than tweaking the report layout in your code.
.4)Get rid of the dot matrix and replace it with a laser.
One of my reports produces barcodes on, standard sized, small labels.
Every time my client changes their laser printer I have to tweak the report by a few millimetres.
Good luck...
You always pass failure on the way to success.

Hey all, im reading a text file and displaying its output in a textbox. I am also making "Next" and "Previous" buttons so the user can go back and forth at will.
The text file looks like
aaa 333
bbb 444
ccc 555
ddd 888
ggg 111
The forward button works fine but I can't figure out a way to go back to a previous record. Any ideas on how this could be accomplished?

Hi, for lists that are line oriented (i.e. words don't suddenly wrap and move to another line)
you should consider a ListBox; it is much more flexible and efficient, and it knows how
to scroll every way you want.

put them in an array and work from i.
Dim Records() as string = file.readalllines("c:\example")
Dim CurrentRecord as Integer = 0
on forward:
if currentrecord < (records.length - 1) then
currentrecord +=1
me.displaytextbox.text = records(currentrecord)
end if
on backward:
if currentrecord >0 then
currentrecord -=1
me.displaytextbox.text = records(currentrecord)
end if

and some boundary checking would be advised too.

You people are vb gods, like seriously ... this thing works perfectly .. does the exact thing that I wanted ... but I'm a bit not satisfied ... why? I want to know how this is really working ... I don't understand how it works ... in the conditional statements, what is really being compared?
On forward:
if currentrecord < (records.length - 1) then ...
what does the current line number (currentrecord) have to do with the length of the record (record.length)?
Sorry if i'm annoying ..

ok so what i did was create the currentrecord variable to keep track of exactly that, the record that is currently open. But how does it find each record? Well...
Dim Records() as string = file.readalllines("c\example")
This line makes a new array of strings (without affecting the contents of the original file), if your not sure what that is, best to google it, but i will explain breify. An array creates an indexed list from a given source that can be quickly an easily accessed.
For Instance, when we did the above line, the array would be visually represented like this.
Records(0) = aaa 333<br />
Records(1) = bbb 444<br />
Records(2) = ccc 555<br />
Records(3) = ddd 888<br />
Records(4) = ggg 111
Notice how the indexing starts at zero. Therefore there is the last item in the list (the fifth) has an index of four.
The Records.length gives us the total amount of items in the list. So...because each item has an index of one less than the amount it is, the last item has the index (records.length - 1).
So. Say for instance our current record is 4 (ggg 111). When we use the line you asked about it will check if this is less than the final item, and will do the appropriate action. However because it is the final item it will do nothing, as trying to display one more than this would result in an IndexOutOfBoundsException meaning that there is no such item.
If you veiw the statement in full, you see that by the time we get to line 3, the current record integer is equal to 5, which won't work. If an item with the specified index does exist than this is what we call 'within bounds'.
1 if currentrecord < (records.length - 1) then<br />
2 currentrecord +=1<br />
3 me.displaytextbox.text = records(currentrecord)<br />
4 end if
The if statements are basically error prevention, they stop your program crashing when there is no data where you are asking for it.
