Error : An Unhandled Exception Of Type 'System.StackOverflowException' Occurred
Jul 13, 2009I am working on a multi-form code. For some reason, this randomly began happening just about the time I finished my code. The intial form loads just fine, but when I go to click on any of the selected buttons, the code crashes. and I get an unhandled exception of type 'System.stackoverflowexception' occured. Does anyone have any ideas? I have checked for any subs calling subs that call subs and I don't have anything of that nature. It is breaking at the point that is bolded and underlined.

An Unhandled Exception Of Type 'System.StackOverflowException' Occurred In Mscorlib.dll?
Apr 1, 2009I am Using Visual Studio 2008 Express edition (.NET Framework 3.5) ... I got this Error when Using A recursive Call To a Function .. I have 3 Background Workers Which Select Data From Database With Status =0 , Take The file Name And File Path Asssosiated With That record, and Then Copy it to other place and on successful completion update the status to 2 otherwise to 3 . and again searech for other record having Status 0 and so on ..
i made a method for selection of record from database every worker call this function . Now I have a check when dataset is filled i checked is there any row ? if yes then it do the rest of work otherwise agin call it self to search for the record...ECURSION.. In Case of records with status zero , It works Fine But in Case of no records Which have status zero it recursively calls itself For approx 1.5 mints and then throws The Exception That " System.StackOverflowException occured in mscorlib.dll at line "DataAdapter.Fill(Dataset,Table)" . I have no Idea what to do with this ..
Eventhough I have Encloesd It in Try...Catch Blocks but It didnt Cath It .. I serached The Internet and msdn social help for it and i found that it occurs most with infiniteloop or Infinite Recursive calls. i know it is due to my recursive call to the SelectData Function But i have no option without it?And One thing more that this project i mean the exe of this project is concurrently runs with another project Which add data to the databse about Filename Filepath and status =0 for Fresh entry..

System Keyboard Global Hook - Prevent Any Other (local) Interception?
Feb 20, 2010My final goal is that striking F12 prints the date (through SendKeys) in the application/window having currently the focus (Word, Excel, Outlook, whatever). I have consequently implemented a globak keyboard hook (system-wide), which is running well (source code below).
My concern is that I would like to prevent any other local treatment based on F12. For instance, striking F12 under Microsotft Word prints the date is the open document (which is fine!) but also launches the "Save as..." dialog box, since F12 is a local shortcut/keybinding under Word. (Actually, the date is printed within a field of a the "Save as..." dialog box). I want to avoid this.
In other words, my aim is to improve the "hook" below so that striking F12 does what I want (which is already the case) but nothing more. That is to say, I would like that, except my treatment, the system "forgets" that F12 was striken.

Bad VkCode In Low Level Keyboard Hook?
Feb 26, 2009I´m using the SetWindowsHookEx API to hook the keyboard, and it works, but when I get vkCode from the structKBDLLHOOKSTRUCT it gives me way too high numbers instead of the ASCII byte I expect to receive. Also, the numberchanges each time I press the same key, so obviously something is wrong. I´m on Windows XP 32 bits, VB 2008 Express, Net. Framework 3.5 SP2. This is the relevant code (condensed, will

Jan 23, 2010I'm using a textbox to define a hotkey, and I need to make the textbox receive key events and prevent the form from receiving them.The reason it's a problem is because Tab (and probably other keys) is a valid key, but the form uses that as a shortcut, so the textbox never receives the keypress.
View 5 RepliesHow To Set Global Keyboard Hook On Separate Thread
Apr 29, 2012After many searches i end up using this class for global keyboard hooking. Link: Global Hook post [code]My app is performing operations that take some seconds to complete (ftp upload small files on interval), and during this time the hook lovks the keyboard. This i dont want of course..I cant jump to Async FtpWebRequest right now because it needs many changes, so i thought that the solution would be to make the hoook live in another thread.A proposal is to move my time - consuming operations (upload) to another thread.Upon doing this i am facing other problems. Because the time consuming task (upload) is in a timer i would have to rewrite a big portion in order to synchronize the file->save with the file->upload and i dont mind the app locking for 3-4 secs. what i do mind is to loose the kayboard for 3-4 secs.
View 2 RepliesKeyboard Hook In Module Closes Immediately?
Apr 17, 2010i am trying to make a app that loads a keyboardhook from a module on startup,
but unless i load the keyhook from the form the app just closes immediately.
i uploaded the keyhook module, to test it just start a new project, add the module,
to test it loading from the form just put hookkeyboard in the form load,
but what im tyring to do is have the module load first, so set the start up object to sub main
what this is suppose to do right now is just send a msgbox on every keystroke, it works from the form load but fails when loading from module, unless i am always typing something.

View 4 RepliesLow-level Keyboard Hook Unhooks At High CPU Usage?
May 3, 2009I have a program that uses low-level keyboard hooks, because it's a program that needs to be able to catch keystrokes, even when holding down capslock or what so ever.
Anyway, I figured out (by making a sample program running at the same time on purpose consuming 95% CPU by making an infinite loop with nothing in it) that low-level keyboard hooks stops working if the CPU usage is that high, and you do a lot of typing what so ever.
