I think you have answered the question yourself.

BTW: The original code looks very much like C, not C#.

BTW: I read everything (everything in latin alphabet), but I don't speak VB
so I will not provide VB statements.

These are errors, the list may be incomplete:

Cory Kimble wrote:
nextone = nextone << 8 And (&H7FFFS << n - 1)

1. n has not been assigned a value yet.
2. I don't get what you are trying to do; the C code was next=next<<8;
Together with 1. this probably explains all the zeroes you are getting.

Cory Kimble wrote:
For n = 8 To 0 Step -1

3. the loop must execute 8 times, not 9

Cory Kimble wrote:
If (nextone Xor crc) And &H8000

4. Does this compile ? the C code
if((next ^ crc) & 0x8000)
is shorthand for
if(((next ^ crc) & 0x8000)!=0)
I don't know whether VB accepts it without a zero-compare.
It is proof the original is not C#

That's it for now.
If you have to publish again, please do it again with original and yours, in
PRE tags, as you did; but then include the definition of crc variable, and
the calling code (initializing crc, looping over the data, etc).

Good luck!

I'm assuming you're form is maximized in the mdi form
if that is the case it's very difficult to remove the form icon

the only way I have found untill now is to set the controlbox property to false, downside you lose alle buttons (minimize,maximize,close) so you'll have to add those yourself

Why does my TabPage not show?

My form has a TabControl consisting of several TabPages, one of which is called processingTabPage. When the forms Load event fires I remove the processingTabPage for the TabControl's TabPages with :-

TabControl.TabPages.Remove(processingTabPage)

When a particular event occurs I add the tabPage back onto TabControl

TabControl.TabPages.Add(processingTabPage)

Then I would like the processingTabPage to show to the user automatically.

TabControl.TabPages(TabControl.TabPages.IndexOf(processingTabPage)).Show()

All works ok accept the showing of the TabPage to the user. Why?

I believe you want to set the TabControl.SelectedIndex or the TabControl.SelectedTab. If you are using .net 2.0 there is also a new method in the TabControl called SelectTab().

Hope that helps.

Obtaining Number Of Pages in Crystal Report

KeithF27-Jul-07 1:00

27-Jul-07 1:00

Hi Guys

Does anybody know how i can obtain the number of pages from a crystal report (version 8.5) using VB 6 before i call the print function. My current code is:

Dim rep As Report<br />
Set rep = CreateReport("Report.rpt")<br />
rep.PrintOut False

The PrintOut property supports optional properties to specify pages from and to. Basically i want to specify these before calling printout as only the first 200 pages are printing even though there is 500 pages in the report.

If i could get the number of pages i can call the printout method a few times passing it different page numbers each time.

Thanks in Advance
Keith

Selecting tabs on a tab control

Hello,

I am using a tab control with each tab created at run-time.

I am using the SelectedIndexChanged event so I can process some data that has been input on the selected tab. However, I need to know which tab the user has just left, so I can process some data that is needed before that tab loses focus.

The selectedIndexChanged event is good for finding the tab that has been selected, but not the one that has just lost focus.

I could proberly loop through all the tabs and find the one that has lost focus, but I am wondering if there is a better method.

Many thanks,

Steve

one possible way would be to store the selectedindex from the tab in a variable
then in the selectedindexchanged event you process your data and after that you set you're variable to the new selectedindex

If you are using .net 2.0 there is a deselected event where the sender being passed in is the tabcontrol and the selectedindex of that tabcontrol is the tabpage that is losing focus.

Hope that helps.

So I think the deselected event should work pretty good for you then. The SelectedIndex and SelectedTab should still be the previous TabPage.

Open an existing Excel (.xls) file & pull data from cells

Q1/
If this is the path to save an open Excel file running in the background

xlSheet.SaveAs("c:\My Path\tk" & Format (Me.MonthCalender1.SelectionStart, "yyyyMMdd") & ".xls")

How would I open a file using the MonthCalender1 (Change-Date) as the trigger to determine the name? e.g. "tk20070727.xls" ?

Q2/ Having opened the file (running invisable in the background), how can I pull the data from a cell to a variable?

Q3/ How do I close the invisable running .xls file in runtime?

There is no event if the phone is picked up... Whatever you have the phone connected to, I'm assuming it's a modem, has to be able to send a message to the PC. AFAIK, there is no modem out there that will tell you if the phone goes "off-hook".

To do that would involve some complex code, as you'd need to hook into the existing save as dialog, or just create your own copy of it.
