Re: Vb.net apps require internet access to run? Emetz56430-Apr-07 22:47 Emetz564 30-Apr-07 22:47  Thanks for answering. Regarding question #1: The apps in question aren't using any network or internet related controls.Just your basic combination of buttons,text boxes, notifyicon, etc.I guess I'll try a network sniffer and see what they're doing. Regarding question #2: If the FSW is only watching the destination folder, shouldn't the file created event in the temp folder be ignored? Eric. Re: Vb.net apps require internet access to run?

Emetz564 wrote: If the FSW is only watching the destination folder, shouldn't the file created event in the temp folder be ignored? It is being ignored. The FSW only watches the target folder. When it starts, it enumerates the files and their Created and Modified DateTimes, along with other things. Every once in a while it makes another list and compares the two. When a new filename shows up or a file with the same name has a new Created time, it fires off the Create event. If a file disappears off the list, Deleted event. If a file has a new Modified DateTime, the Changed event. Now, Renamed is a bit different. The FSW CAN detect a renamed file, but, for some reason, not in all cases. It depends on what the application is doing that is modifying the files. Either the Renamed event is going to fire, or the Created event will fire, maybe along with the Deleted event. It probably has to do with a timing issue when the FSW scans the target folder(s).

I'm trying to write an application that detects a mouse click on a video (target acquisition), working with still pics (jpeg etc.) worked great but when I play a video (using MMcontrol) the clicks are not detected. I'm using VB6 (thats what the U offers) and directx9 (on XPsp2) Thanx in advance , have fun ya all. Re: detecting mouse click on a form playing a video Dave Kreskowiak30-Apr-07 10:09 Dave Kreskowiak 30-Apr-07 10:09  I haven't used the MMControl in, what, 8 years. But, IIRC, it doesn't give any Click events for the video window, just the control bar.

Re: detecting mouse click on a form playing a video Dave Kreskowiak5-May-07 3:42 Dave Kreskowiak 5-May-07 3:42  Well, I don't know if it's possible, because I just about never touch DirectX, but if you have the capability to tell DirectX which window to draw in, you can use a PictureBox control as the target window, then handle the Click event of the PictureBox.

The RichTextBox wasn't designed to be a colorizer. It'll work, but not good. THe problem is that the user is still modifying text while you code is trying to modify it too. That's not easy to control. Depending on the method you chose to do the coloring and put the RTF back into the RTB, you can be overwriting the changes the user is making to the text, while your colorizing it. Since we know nothing of your code, it's really impossible to say anything other that refer you to an article like this one[^]. Dave Kreskowiak Microsoft MVP Visual Developer - Visual Basic      2006, 2007 Special Datagrid sort Dayekh30-Apr-07 4:16 Dayekh 30-Apr-07 4:16  Hi, I have a list of records. Those records have a field called Progress. There are 4 Progresses. 'Pending', 'Work In Progress' and 'Completed'. If I sort by Progress in ASCENDING, then the order will be: Completed Pending Work In Progress If I sort by Progress in DESCENDING, then the order will be: Work In Progress Pending Completed I need PENDING to be at the top. So that all the records which are PENDING will be at the top and the rest can be sorted as normal. Any ideas how I can do this? Thank you. Re: Special Datagrid sort kubben30-Apr-07 4:35 kubben 30-Apr-07 4:35  Add a new column to the DataTable in memory and set the value based off the Progress column. That way you can set Pending = 1, work in progress = 2, completed = 3. Then in your code take the dataview and sort it. dim dv as DataView = dataTable.DefaultView dv.Sort = "NewSortColumn" Or you could just add a Sort column to your table in the database as well. Or you could move the Process column into its own table and just stored the processid in your table you are returning. Hope that helps. Ben Re: Special Datagrid sort Arun.Immanuel30-Apr-07 5:07 Arun.Immanuel 30-Apr-07 5:07  Or sort based on len(Progress) bcos it has the least length. Regards, Arun Kumar.A Re: Special Datagrid sort Dave Kreskowiak30-Apr-07 9:06 Dave Kreskowiak 30-Apr-07 9:06  That's a really bad idea. I'd fire you if you wrote code like that. What if the status enums change? How about localization changes in the text of the enums??

Anyway, thank U very much. Regards, Arun Kumar.A Re: Special Datagrid sort Dayekh1-May-07 2:18 Dayekh 1-May-07 2:18  Silly me .. I found the easiest and most reliable way of doing this.. Simply add another column in the Database called Progress Number. Pending will be 1, Work In Progress will be 2.. etc.. And then simply sort by "ProgressNumber" Thank you guys for the help. Printing windows form johnjsm30-Apr-07 4:03 johnjsm 30-Apr-07 4:03  Hi, I have a windows form and I want to print the contents of it. Is it possible to do this in vb.net Re: Printing windows form Duncan Edwards Jones30-Apr-07 4:28 Duncan Edwards Jones 30-Apr-07 4:28  It is. There is an article here[^] that gives one way to do it, and there is also an MS control that emulates the old VB6 "PrintForm" command in the Visual basic Power packs...

Can you help. Thanks Re: Printing windows form Duncan Edwards Jones30-Apr-07 11:27 Duncan Edwards Jones 30-Apr-07 11:27  It doesn't work with VB.Net 2003 because the code is written with VS 2005 and uses some of the newer language features such as generic collections. You could just use the compiled component if you have someone who has VS2005 to compile it up for you or move your code to VS2005? (The component is in the source code attached to the article) '--8<------------------------ Ex Datis: Duncan Jones Merrion Computing Ltd Re: Printing windows form sthotakura30-Apr-07 5:47 sthotakura 30-Apr-07 5:47  Check out the below link http://msdn2.microsoft.com/en-us/library/system.drawing.printing.printdocument.printpage(VS.71).aspx[^] Cheers, Suresh Recording a Phone Call S.Rajeshwar30-Apr-07 1:55 S.Rajeshwar 30-Apr-07 1:55  Hi all, I have written code in VB(Using MSCOMM Control) to Dial a phone Number through internal modem.The code is working fine i am able to make a phone call through Modem. But the problem is How to record a Phone Call. Can any one Help me to Record a phone Call Thanks & Regards S.Raju Re: Recording a Phone Call Ray Cassick30-Apr-07 4:21 Ray Cassick 30-Apr-07 4:21  Making the call was the easy part Recording the call is going to be harder. It depends on how you made the call really as to how you can get attached to the audio stream and if your modem even allows you to get it. Personally I like to keep modems for data communication and not voice. They were not really made for voice. Tapi is going to be a pain as it really does not work very well with managed code (no matter what anyone says) and the Unimodem TSP does not support full duplex audio.

Thanks & Regards S.Raju Re: Recording a Phone Call Ray Cassick30-Apr-07 20:07 Ray Cassick 30-Apr-07 20:07  As I said there is no really simple way to do it using Tapi and managed code but I am not even sure about what interface you are using? What kind of modem do you have? Is it a modem that has speaker phone functionality or just a plain modem? Personally I always point folks trying to do voice applications with modems to stop before they put to much work in and make the step to real telephony hardware that is built to do this stuff. Let me know if you are ready for that. Its not cheap but I can help out a bit with the programming aspect. My Blog[^] FFRF[^]
