Thanks, Werries A programmer's life is good... or is it?? Ek dink nie so nie! Re: Determine if Windows is shutting down The ANZAC6-Jul-07 15:30 The ANZAC 6-Jul-07 15:30  i believe windows executes a batch file to initialise shutdown sequence, perhaps you could use the filewatcher to monitor this file for changes, then if something happens with it, check if the shutdown process in is started through system.diagnostics.process.

How to display rich text contents from a database field into crystal report 8.5 Salman Sheikh6-Jul-07 5:38 Salman Sheikh 6-Jul-07 5:38  Hi everybody the situation is that an application contains many richtextbox objects and user enters rich text data in them which is stored into sql database (contants from rt1.rtf). Now my task is to display that data into a crystal report. when i drag this field (type of this field is text) onto the report it displays all rtf header information as well instead of formating the actual data Please give me any suggestion you have about it Regards Salman Sheikh Informix and VB.NET penguin50006-Jul-07 5:24 penguin5000 6-Jul-07 5:24  Hi, I've managed to connect to an Informix database to display the contents of a specific table in a DataGridView. What I am struggling with is getting the table and fields names from the database, and putting the information into a TreeView so that the user can select the table in the tree, and update the grid with that selected table - but I can't seem to get it to collect the schema information. Ideally, I'd like to have the first node on the tree as the database name, followed by nodes for the table name, and then nodes for the field names. Could anybody point me in the right direction? Use Radio Buttons Independently of one another RichardBerry6-Jul-07 4:54 RichardBerry 6-Jul-07 4:54  Hi I'm busy with an app that interfaces with the Parallel Port. I want to create a graphic sort of display on my form that looks similar to the actual layout of the DB-25 connector. I thought of using Radio Button to either display the input condition, or to toggle the condition of the outputs (Data Pins) Is there a way to make these buttons independent of each other (i.e. so that clicking one of them does not turn the others off) I though I may be able able to use something like e.handled in the 'Click Event', to prevent the others from tuning off when I click one of them, but no such luck. Basically I want to be able to set or clear any combination of these buttons for the output pins, and also control the appearance of them depending on the port's input conditions. Any other way I can do this? I could use panels, and toggle the pin and the color when clicked, but don't like the rectangles. Re: Use Radio Buttons Independently of one another Luc Pattyn6-Jul-07 5:09 Luc Pattyn 6-Jul-07 5:09  RadioButtons work together, unless you put them in different Containers; keeping them apart is the primary purpose of the GroupBox. Luc Pattyn [My Articles] [Forum Guidelines] Re: Use Radio Buttons Independently of one another RichardBerry6-Jul-07 5:13 RichardBerry 6-Jul-07 5:13  Hi Yep I get that, what I'm asking is: If I can do something to make them independent OR What else can I use that will look SIMILAR... Re: Use Radio Buttons Independently of one another Luc Pattyn6-Jul-07 5:22 Luc Pattyn 6-Jul-07 5:22  if you have two radiobuttons rb1 and rb2 both on panel0, you could create two more panels (panel1 and panel2), put rb1 on panel1, put rb2 on panel2, put both panel1 and panel2 on panel0, and arrange it such that it looks exactly as before. rb1 and rb2 now should word independently (you better have more RadioButtons then!) Luc Pattyn [My Articles] [Forum Guidelines] Re: Use Radio Buttons Independently of one another RichardBerry6-Jul-07 5:28 RichardBerry 6-Jul-07 5:28  Hi Luc That makes them independent... But you cannot toggle them anymore since there is now only one. Basically I want it to LOOK like a Radio Button, and FUNCTION like a check box Re: Use Radio Buttons Independently of one another MidwestLimey6-Jul-07 11:14 MidwestLimey 6-Jul-07 11:14  Set AutoCheck to false and implement a click handler to toggle the checked status. I'm largely language agnostic After a while they all bug me Re: Use Radio Buttons Independently of one another RichardBerry6-Jul-07 22:55 RichardBerry 6-Jul-07 22:55  Thank You SOOOOO Much!!!!!!! Everyone has offered lots of reasons why not to use Radio buttons, but no solution. AutoCheck to false does exactly what I want it to do Thanks again Re: Use Radio Buttons Independently of one another Guffa6-Jul-07 11:50 Guffa 6-Jul-07 11:50  It's generally a bad idea to make an interface look like it should work in one way, and make it actually work in a completely different way. You can for example use images to show the status. --- single minded; short sighted; long gone; Re: Use Radio Buttons Independently of one another Luc Pattyn6-Jul-07 15:36 Luc Pattyn 6-Jul-07 15:36  I agree; conventions exist for a reason.

That is the ONLY reason I wanted to use something like a radio button - I want something that looks NICE, and also looks like the pins on the connector that I can arrange in the same way as the DB-25 connector for the parallel port. As far as functionality, all I need is to be able to set the pin when the object is clicked, and I need to be able to toggle the colour to indicate the logic state of the pin I guess even 'circular panels' would be ok. Re: Use Radio Buttons Independently of one another The ANZAC7-Jul-07 2:12 The ANZAC 7-Jul-07 2:12  have you tried developing your own checkbox that overrieds the paint event and replaces it with your circular functionality, i think that's what you need to do.

Re: Launch myprogram with another at same time sathesh pandian6-Jul-07 5:04 sathesh pandian 6-Jul-07 5:04  hi, you can use process.start("notes.exe") All The Best Sathesh Pandian Re: Launch myprogram with another at same time Craster6-Jul-07 5:41 Craster 6-Jul-07 5:41  There's no way to hook into the launch of notes.exe to know that it has launched. You have two options: 1) Use a batch file to launch notes.exe that will also launch your app. 2) Have a boostrap app permanently running (at startup, or as a service) that scans the running processes, then launches your app when it sees notes.exe is running. Re: Launch myprogram with another at same time Bogdan Apostol8-Jul-07 2:58 Bogdan Apostol 8-Jul-07 2:58  Yes, there is a way. You may not like it though! You can patch notes.exe, such as to modify the entrypoint to a different location, which, obviously, launches your application and then forwards the execution to the original entrypoint of notes.exe! That's how some viruses work, isn't it?

System Watcher File Cory Kimble6-Jul-07 4:31 Cory Kimble 6-Jul-07 4:31  I want to watch a file and update a list with the data in the file. I want my program to call a method in another class to go out and get the data from the file. I place my method call in the OnChanged Sub routine. But, I get and error about Object reference not set to an instance of an object. I put in this code, but I still get the same error. Do you know what I am missing? Dim currentList As frminYardTrucks = CType(currentList, frminYardTrucks) currentList.updateList() Am I doing something wrong?
