You want to actually write a web browser ? That is, not use the web browser control ?

OK, will you support ActiveX controls, javascript, etc ? How many years do you have to do this, assuming you'll be alone ?

I have a multi-page tiff that's over 1meg. I get an 'out of memory' error trying to open it from the method 'fromfile' I have tried 'fromstream' and can't get past 'an invalid parameter used' when everything that I'm using is correct. My ultimate goal is to get a count of how many pages(images) are embedded in the image file so that I can tell how many images a java applet can expect in the file. This code works but craps out of certain files and I don't know why... Any help would be appreciated...
Dim oFile As New FileStream(sTiffFilePath, FileMode.Open, FileAccess.Read)
oImage = System.Drawing.Image.FromStream(oFile, True, True)
'exception -- invalid parameter used
or
oImage = Drawing.Image.FromFile(sTiffFilePath)
'exception -- out of memory
Dim oGuid As Guid = (oImage.FrameDimensionsList(0))
Dim oDimension As System.Drawing.Imaging.FrameDimension = New System.Drawing.Imaging.FrameDimension(oGuid)
iGetPageCount = oImage.GetFrameCount(oDimension)
oDimension = Nothing
oGuid = Nothing
oImage.Dispose()
oImage = Nothing

You'll have to check the compression used in the TIFF. GDI+ doesn't support JPEG compressed TIFF's.

HI,
I have a string eg. 000-000-000-000 and I want to replace the last "-" with an "_"
Can anyone help me to do this.
Thanks

hi,
String.Replace('-','_')
hope this works.
nitin...

Try using regular expressions like:
regex.Replace( yourString, "-", "_")
where regex is the regular expression and yourString is the string in question. Hope this sheds some light

Dim s As String = "000-000-000-000"
Dim i As Int16 = InStrRev(s, "-")
Mid(s, i, 1) = "_"
MsgBox(s)

Will the string always be the same length, as in 4 sets of characters seperated by 3 dashes?

Is this VB.NET ? If so, then you should use the string. methods, not the ones provided. But, any sort of replace method will replace them all. as someone suggested, if the format is always the same, you can use an index to replace the one character that's in the same place evry time.

Hi,
I'm not sure under which category I should ask this. But here goes:
I am trying to implement a search which will allow a user to search for Projects by the 'StartDate'. What they can do is search for Projects:
[Greater Than] date entered,
[Less Than] date entered,
[Equal To] date entered,
[Greater Than or Equal To] date entered,
[Less Than or Equal To] date entered.
I have a subroutine which passes the date inputted by the user to a method in a class file.
This method accept the input as String.
I would like to know how to proceed with determining how to tell the system to check if the input date is greater than, less than, etc..
I mean.. SQL can say 2 is greater than 1, but can it say 01/01/2006 is greater than 01/01/2005 ??? If not, do I need to do anything in VB.net?? Or even so, do I need to do anything special to the SQL Query ?
Please help. Thank you.

Wouldnt you also need a parameter to say how you want the dates compared? Greater than / Less than / ...
All relational databases support date comparisons, provided that you have defined the column as a date type.
|
|
|
|
|
Ah I see. So what you are telling me is that SQL Queries will understand that 01/01/2006 is GREATER THAN 01/01/2005.. even tho they are DATES and Numbers.
That's all I needed to know ... for now >=)
Thanks for the reply.

By an chance are you using a Timer somewheres that triggers the event every two minutes?

Hi,
I want to put together an application which allows the user to enter prices from their suppliers.
In a lot of cases, suppliers offer price breaks - so the more the customer buys, the cheaper the unit price will be for that item.
My question is two fold ....
1. Is the DataGrid the best method of recording prices "from" and "to"? I suspect it is, but if there is a better method, I'd be interested to hear.
2. If the DataGrid is the best method, how do I validate the entries to ensure that the user is filling the grid in correctly? For example, if the user enters a price for 1 to 10 units as being £1, but they accidentally enter a second price for 9 to 20 as £0.90 - how do I catch it?
Thanks in advance.
