Control has an Invoke method that should be used when you need to update a control from a thread other than the one that created it. Use InvokeRequired to determine whether it is necessary to use Invoke. Charlie if(!curlies){ return; }

Hi Peter, This is generally a permissions issue. Make sure the ASPNET user has read and write rights to the folder containing your MDB. Hope that helps! Datagrid Girl

I must have asked in the wrong way: The real question is how can I serialize a treeview into a file so that I can retrieve its nodes any time. When I expand an item, I have to read in its childs from the file, when I collapse delete all items in this node because all subitems are saved in the file in question. Anyway thanks for the feedback. Bunburry

I have used a memory mapped file in a number of projects for interprocess communication where I managed data streams in both directions. I didn't make my point clear enough, I meant if you're using a Garbage Collector, the pointers move around, if you save the pointer to a file, you must explicitly lock the pointer, if not, the ponter is read but doesn't point to the right address.

RaGe, thankx for your reply. Example: a remote pressure sensor, which has an output current signal 4-20 mA (4mA refers to 0 pressure, 20 mA refers to maximum pressure, 10 barg). I have have to display the pressure as a function of time. 4-20mA is a 2-wire cable which I cannot connect to the serial port, as a result of which I will need an adapter which would convert a 2-wire current output of pressure sensor to an understandable signal for the serial port. I am interested in any kind of equipment which can directly be connected to the computer over serial port. Thankx Bunburry

Case solved. I will always remember to call if (pProgressDlg->CheckCancelButton) pProgressDlg->DestroyWindow(); in the loop of my worker thread. Thanks anyway for your help. Bunburry

Hi, Well, I recommend you to use ADO, it´s more or less "modern", quite easy to use, and quite powerful, but that´s only to work wit the data, to visualize it you have to use some ActiveX controls ( for example a free on it´s DbGrid that it´s shipped with VStudio). Here in Codeproject you can find a lot of help on that. An easier to use thing could be ODBC, but is more or less the same job... HTH Braulio

Well if you're looking into getting rid of it and you have a Win 9x system have you tried "fdisk"? Just thought I would my two cents :-) Sam C ---- Systems Manager Hospitality Marketing Associates

I can't tell from your code snippet, but the "Here comes the code that uses the interfaces" part probably uses all three interfaces. Thus all three QIs have to succeed before that code can work. And BTW it'll be easier to understand if you replace "!FAILED" with "SUCCEEDED" :) --Mike-- http://home.inreach.com/mdunn/ "The Earth is doomed." -- Rupert Giles :love: your :bob: with :vegemite: and :beer:
