I'm planning on using the Smart Device Framework 2.3 to use the signature control panel in a Windows Mobile 5 application using the compact framework 3.5.
The control has the option to save the signature as either a byte array of points, or as a bitmap. Now seeing as I want to store the signature in a sql compact database, I guess the byte array is going to be better. The trouble is, I'm not sure how to render that in a full WinForms application after I've transferred it back to the desktop.
I need to show the signature on a report, so it would need to be an image I could link/embed into the report.
I would like to implement into my program a version query of the executable and I figured the easiest way would be having a check on the date of the executable. So how can I check the creation date of the executable that is currently running (from the program itself that is)?In short - double click on .exe and it will tell the date of its creation

View 1 RepliesI have a program that outputs a file. I want the user to be able to just double-click the output file and launch the program, just like Word and Excel. In Word for instance, one doesn't necessarily have to open WORD then click on File--> Open and locate another Word doc. He can just go to the folder and open the Word doc. I want to implement the exact scenario in my program.
So far I have tried creating TextFile and added it to the Resources. On FormLoading, I simply I stream-read the Resouce file, but I can't write to the Resource on FormClosing, since the Resource is ReadOnly. Also, the Resource is built & compiled so I suppose you can't add anything to it at run time.How you lunch an output file without launching the Executable program that created it?
I have an executable that I was able to get working on all XP machines by registering all the .dll's associated with it.On Vista, however, I go through the exact same registration process but right when I open the executable it goes to a "WindowsApplication1 has stopped working" dialog. I registered the DLLs in the SysWOW64 folder. I also ran Dependency Walker which came up with IEFrame.dll as flagged, don't know if that is relevant though.
View 6 RepliesI have an application that has file extensions associated with it. The application has been deployed using ClickOnce. I have checked the associations table to confirm the entry is there and the association is to the 'ClickOnce Application Deployment Support Library'. When the application is triggered using a file with my extension, it does not pass the filename / directory in the CommandLine Arguments, instead you get the executable path of the application.
Which is under ..LocalSettingsApp"Random Strings"MyApp.exe
I have checked the Registry entry to confirm what the extension is set to open with and the application is dfshim.dll. Is there a way to overcome this, or is this just another limitation of ClickOnce deployment?

View 1 RepliesI have a txt file with a few settings that get loaded into the Program. These are put into an array. As the array holds different types (int, string, dates etc) its set to object type.
What i am trying to fingure out is how to check the date is a valid format, by returning a false value so i can have a msgbox pupup and say the date in the file is invalid. I cant use isdate() on the string from the file as even if the date format is correct its a string not a date type so i have to convert it first (which is the point it throws an error).
I need to check if a character is a valid Key (type) in VB.NET (I need to turn "K" into Keys.K, for example). I am currently doing this to convert it:
Keys.Parse(GetType(Keys), key, False)
I have an VB.NET application. This Application is permanently resident in memory and minimized to the tray area because we use it very often. The problem comes in when we VPN into a client's site. These VPN connections trash all other network connections to and from our machines.Then every time my VB.NET application refreshes its database, errors start occurring, because the machine has lost connectivity to the SQL server, however, these are not at the connection level, but only when the reader attempts to read.
I am checking for connection.open, but because of the SQL connection pooling, I just get a previous connection that was valid before the network was cut. Is there anyway to check if an actual SQL connection is valid, prior to re-issuing a connection from the pool?[code]...
After I send a post request to login to a site (using httpwebrequest), how do I check if the login is valid?
One way to do it is to read the whole html using
dim reader as new streamreader(response.getresponsestream) dim str as string = reader.readtoend and then check the html for any unique string (e.g. "log out"), to tell if the login is successful.
But reading the entire html is too long, so how do I shorten the process?
I tried
Dim str as string = response.getresponseheader("Set-Cookie")
But str is a blank string.
