I want to communicate with a Finger Print Machine but no SDK /APIS is provided by the client bcz vendor wants to sell SDK separately , its Pinging but how i can send and receive data without having any SDK or manual.
Is there any way that i can communicate with any machine and can send and receive thumb impressions without having any SDK or manual.
If so then is not it like developing a VIRUS/Trojan or something.

You need to speak to the manufacturer or distributor of the device.

You'll have to contact the manufacturer of the device for the SDK. There is no getting around this.
Also, where did you get this thing from? Every fingerprint scanner I've seen always came with a copy of it's SDK.

Actually the Manufacturer is selling SDK separately three times more then the Price of the Machine and client does not want to pay

Then client doesn't get their solution, now do they?
The manufacturer has you over a barrel. You can try a third party library, but you're not going to get the full functionality of the scanner. You can find some by Googling for "fingerprint sdk free[^]".

Hi everybody,
I'd like to make a little application to handle 3rd party gauges. These are basically C/C++ dlls, so it seems that I have to find out their entry points and members first. One major thing would be to simply show the bitmaps, which they provide for the GUI in the game (MSFS), inside my application.
Does anyone know a way how to do something like retrieving member and resource information from an unknown dll in VB.NET (or C#)?
Thank you
Michael

Thank you, I'll go google for these tools.

This seems to be a really cool tool for the initiated ... giving me what I asked for and showing me how far I am from "making a little application" with display support.
At least the dlls in question obviously don't expose any bitmaps, but only "ImportTable" and "Linkage" functions which both belong to a world of C-language and the 7 seals...
Thank you still!

Hi,
I have this table
Accessories table
(ID, description, date, ArmoryID, ProfileID)
with these records:
1 belt 05/01/2010 1 1
2 hoslter 05/02/2010 2 1
3 charger 05/03/2010 3 1
I need to take the most recent record for profile 1
to have as result: (3 charger 05/03/2010 2 1)
I tried a number of querries, can't seem to get the right answer.
Please guide me through it..
Thanks a lot..

Select count(*) from Accessories, the result is 3, then select * from Accessories where ID = result
|
|
|
|
|
Hi
thanks, but we will not know what the result is..
One profiler can have more than one accessories as of in history archive.
but to check to see if a profiler has an accessorie, it should load based on the most recent date since we can have more than one accessories entries for one profiler.
Hope a bit clearer now.
thanks a lot

SELECT * FROM Accessories ORDER BY date DESC; , then use the first returned record.
By the way, using "date" for a column name is a very bad idea, since it is a reserved word for a data type in most SQL dialects. I always use "order_date" or some other variation to make sure the SQL engine doesn't think you are using a reserved word. Sooner or later that problem will bite you.

Hi,
Thanks.
I have used a variation for date..again thaks for the info..
I thought of doing it this way..wasn't sure if it was the right approaoch..
thanks..
|
|
|
|
|
Instead of returning the entire ordered set, how about returning SELECT TOP 1 ... ORDER BY date DESC instead?
|
|
|
|
|
Yes, you're right. When I need to do that, I usually end up needing more info, so I usually just get the whole set, but if he really needs just 1 and only 1, selecting TOP 1 is the way to go.

Question: Is it possible to have two (or more) entries with the same date?
If so, then sorting on date descending and selecting first one (e.g. by using top) is not guaranteed to get you the most recent entry.
If the ID field is autogenerated then perhaps the max of that is a better candidate?

I have an MDI Application that I am developing using Visual Basic 2008
One of the forms that the application calls in inside a DLL. This works great
Imports articleSearch
Dim frm As New DocumentSearch("Broker", Me)
frm.MdiParent = Me
frm.Show()
My problem is that form spawn another form from the DLL depending on the user action i.e. documents to view.
For Each dgRow As DataGridViewRow In DataGridView1.SelectedRows
'MessageBox.Show(dgRow.Cells(3).Value)
Dim frm As New PDFViewer(Trim(dgRow.Cells(3).Value))
frm.MdiParent = _CallingApp
frm.Show()
Next
now if i use the frm.mdiparent = _CallingApp (where _callingApp is a reference to the form being called) then the form display is blank but if i omit that line it works as expected, but it is no longer a child window of the mdi app
any pointers?
Thanks

What do you mean with the 'form being called'?
I would either put a reference to the MDI form in a class and use that one.
Or just use me.parentform instead of _CallingApp

Sorry Tom,
In my App I have the main exe and a DLL.
In the DLL I have 2 forms a document search form and a PDF viewer.
each of these forms are called by the main App (MDI parent)
I can call the document search and that works ok, but then the user clicks on docs to view and click on the view selected button. But I want to get the PDF viewer as a page in the MDI Application, if I set the parent no document shows (just a blank screen). If i ignore the mdiparent setting it works as expected but the user gets 1 to many pdf's open.
My question is how can I get the PDF viewer screen to show up inside the MDI Application only.

To get it to open inside the mdi application you have to set the mdiparent of the form.
So either the _CallingApp reference is wrong (not a reference to the mdi parent form or something in your pdf viewer is going wrong when called into a mdi container.
