View 8 RepliesThe following code is designer generated:

What's the 8.0! mean?
i was asked to do a program which can find if a 2d point is inside a triangle or not, only the 3 points of the triangle were given. i planned to do this using the slopes of the 3 sides, then with y-y1=m(x-x1) using the other vertex and the point being checked see if the slope was the same sign and on the same side of the line. if this was true for all 3 then the point is inside the triangle the problem is i cant think of a logical expression for the if/then/else structure to show this anyone know what i should use or should i just go down a completely different route?
View 3 Repliesassuming i have an isoceles triangle, where i know the height + base width, how
can i calculate the width of that triangle at 1/3 of the distance from the point + 2/3 of the distance from the point?
i thought it'd be simply 1/3 base width + 2/3 base width, but my drawing is +/- a few pixels when i resize it?

I have a routine where I click on an image in picturebox1. When the user clicks I need picturebox 2 to show a section of the image in picturebox1 centered on the users click but zoomed in. I have the following function which is doing exactly what I want it to do (except properly zoom in.) I have been able to achieve something that appears to be a zoom but it no longer centers on the clicked point.

I'm looking at inherited code and I found this in a vb.net windows form:New System.Drawing.SizeF(6.0!, 13.0!)My question is, what is the significance of the ! (exclamation) operator here? Most of my searching for the exclamation operator ends up returning recordset format or the ! gets ignored in the search and I get hundreds of unrelated items.
View 4 RepliesIn my application I have bound a datagridview to a SQL2005 bindingsource.I really had to change a database field (more length allowed) and now de DGV displays red exclamation marks and states: 'Colomn 'password' exceeds the MaxLength limit'. (the 'password'-colomn isn't even displayed, but that's a sidenote).I tried different things but can't get rid of the exclamation marks. how I can manage this. I really don't want to create a new DGV, because there a lot of code and stuff involved.

View 8 RepliesIn a Windows XP Pro environment, my system uses a mainframe emulator in a window in which a scanning application is running. The data populating the mainframe app comes from various instruments, scales, barcode scanners, etc.. The data inputs are captured by a winwedge type RS232 data aquisition software.
When all the data is processed correctly, the mainframe application sends an "operation completed" message and creates an exclamation system event associated with a specific sound to inform the user.
My goal is to create a MS Access application that would use the Exclamation system event to validate writing the barcode that was just read to a database without further querying the mainframe, creating a local database. I only want to write the barcode when the mainframe application completed and therefore played the sound.

View 2 Replies1) the program has to display multiple lines, is there any possibility for me to add some sort of scroll bars to the msg box and fix its size to lets say (infinite horizontal because i limit the char of each line already)600vertical.And if theres more text than the textbox vertical to display scrollbars like a richtextbox? is such thing possible? if not
2) How could i create a form which interacts with the program exactly the same as a msgbox, by that i mean a way to not interact with any other form but the msgboxform untill the msgbox form is hidden. I do not want to disable the other forms or hide them, because a msgbox does not do that, a msgbox just doesnt let u interact with anything untill its pressed "OK" button, and if u try to interact with something else a beep happens and the msgbox flashes, is such thing doable?
3)How could i hide a msgbox and inputbox programatically? imagine the user is afk and doesnt press OK, with a timer tick i want to automatically erase the msgbox out of the way. Is such thing possible? if i need a form, it really is a musthave for me to someway pause the code of the other form the same way a msgbox does.
