I am attempting to send the PrintScreen key, obviously, which ought to work no matter the window it is focused on. How can I make this trigger the printscreen action like it normally would? This is in VB.net. I have googled this, and couldn't find any results that worked.
View 1 RepliesI am designing a program that will show a reminder form when the computer is shutting down. (The reminder is to go outside and get the Bluetooth gps aerial.) I have tried using the formclosing event, (triggered by windows shutting down) to flash the form up on the screen using windowstate = normal. (At loading, the form windowstate = minimised). This did not halt windows shut down and the form was only on the screen for a fraction of a second before windows shut down. Can I trap windows shutdown until the form btn_Yes has been selected?
I think this msdn library article is talking about this. [URL]
I have looked at the enumprocess api, but this is quite a bit outside my current knowledge level. From what I have read, enumprocess would be suitable as we all run the same program on our laptops and I could check for the change of state of that program. Eg. �OK, program A is closing, the computer must be about to shutdown, so flash up the reminder form.�

View 2 RepliesI have a main form that has a dynamically generated treeview and also a panel control. Depending on the selection made within the treeview the panel docks 1 of three diffrent usercontrols which are full sub forms(done for ease of modifing design of sub form rather than layering panels on top of panels).Upon button click withing usercontrol i wish to trigger event within main form.For example delete button wich then triggers to remove current selected node from treeview. code for 1 of three diffrent user controls
Dim ctrlQ As New QuoteUC(TrViewQuotation.SelectedNode)
PnlSubFormDock1.Controls.Add(ctrlQ)
Code for delete button for which i need to raise event.
If MsgBox("Are you sure you wish to delete this customer ?", vbYesNo, "Delete Record") = vbYes Then
Deletecustomer(n)
End If
i have to develop a software for motorola mc9090 that reads barcodes and rfids simultaneously, so i need to catch two different triggers: the one on the keyboard for barcodes and the other in the backside for rfids.the problem is that i didn't find any sample that illustrates how to set the trigger to read only barcodes, i found something on emdk 2.5 samples that shows how to set the trigger to read rfids but nothing for barcodes. So when i press any trigger the barcode reader is always enabled with rfids reader.Does exist a way to manage them with separated triggers?

i want to take a printscreen at my application when a msgbox it's in foreground..When the programs get into a catch block, i display a msgbox with the error to the user, and the user must click yes or no to send the info to the database..BUt to send the info to the database i need to take a printscreen to the error message with all info of what the user was doing in my program...
If i use a different thread to show the messagebox i only get the image of the messagebox, if i use the same thread i can't take the picture (if i can i don't know how).So i need some help to take a picture to the messagebox with my program in background and then wait for user response to the messagebox.
I found that code somewhere and I find it quite useful but I would like to find a way to make it work so it capture only the given window target. Maybe with a processID or Window Name. Even if that window is not active. I do not want to make that window active but want to get a screen capture like if I was doing Alt+PrintScreen on it.

View 8 RepliesMaybe there is a better way to do this. The jist of I want is to have SQL Server raise me 2 types of errors: a WARNING and an ERROR from a trigger when I update a table. If SQL server returns a WARNING the trigger should COMMIT but show the warning to the user (using .NET - preferably through a SQL Exception which is only raised if severity > 10) and if it is an ERROR the trigger should ROLLBACK and show the ERROR to the user (through a SQL Exception).My attempts (needless to say this isn't working) at this was to have a trigger like this:
ALTER TRIGGER [dbo].[TR_TRANSACTION_UPDATE]
ON [dbo].[tTRANSACTION]
FOR UPDATE

View 1 RepliesI have a CRM application that I would like to programatically post new records and updates to, based on values in other tables getting inserted or updated. Problem is because of how this CRM app was designed I cannot use straight SQL insert/update SQL commands. This is because the database has some proprietary account#/record ID generation algorithm, and also writes to a log table using some pretty cryptic looking values.
The only way to ensure the integrity of the data is to use a the COM based API they provide. How can I send calls to this API from SQL Server code, I'm guessing a CLR user defined function? Can anyone point me to such tutorial on the web?
The updates I am making MUST be in real time, that is why I need to use a trigger that calls this app's API.

Me.Tb_inventory_datesTableAdapter.Fill(Me.InventorySysDataSet.tb_inventory_dates)
Dim inventory_date As Date
inventory_date = Me.cboInventoryDate.Text

Upon clicking the editbutton will execute EditForm.ShowDialog()
And in my EditForm the record will be updated, after which will trigger ViewProductsInventory.btnSearch_Click( ViewProductsInventory.btnSearch, EventArgs.Empty)
And then the error "Conversion from string "" to type 'Date' is not valid" occurs.
I tried Msgbox(Me.cboInventoryDate.Text) and returns nothing. I'm assuming that my cboInventoryDate is not being populated at this time therefore when btnSearch_Click is triggered it receives nothing.
