I'm using code from here - [URL]. And I'm getting the old
A call to PInvoke function 'EliteSwitch!EliteSwitch.MouseHook::CallNextHookEx' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.
Error on this line
Return CallNextHookEx(MouseHook, nCode, wParam, lParam)
I've tried changing variable types but I can't get it.
The GetAsyncKeyState Api does'nt recognizes the mouse wheel rotation, I see.Is there way to control the mouse wheel rotation (always, not only when the pointer is over a form of mine) with a simple API, without to Hook the mouse?
This was the code and this is the thread HERE Ok its working and everything but when i want to perform something when click is noticed it says i cant cross-threads
I have a app that updates an Access Database via a datagrid view. I'm updating two column of type Single. The code works perfectely when the regional settings are default US-EN.For computers running in germany an update to the backend database throw a datatype mismatch error. I change the decimal separator on the computer with 'German' for region settings from Comma (,) to (.) period and everything works fine.I add thread culture to US-ENG at the startup of the application. Now the error disappears but then 2.5 is now stored as 25 in the access database.
I add these lines at the beginning of the application soon after the designer code
System.Threading.Thread.CurrentThread.CurrentCulture = New System.Globalization.CultureInfo("en-US") System.Threading.Thread.CurrentThread.CurrentUICulture = New System.Globalization.CultureInfo("en-US")
This is a MDI app and this code is in the container window...
I am currently trying to develop a chat application which will work on a LAN, however encountering problems with with adding a user through the registration form, always getting the result :: "Datatype mismatch in criteria expression" I've tried checking and cross-checking the datatypes used in both the database(its a .mdb database,, created in Microsoft Access)this is the code i am using:
dim con as new oledbconnection dim cmd as new oledbcommand Public Sub UserReg()
[code]....
everything is done,, such as opening the connection and defining teh data reader, etc as you can see from teh code(which was derived from another question but i made edits to suit my use for it)I also have problems with checking wether a user is online. obviously i will be referring to the table to do that using something like
cmd = new oledbdatacommand("SELECT * FROM Users where isOnline = "Yes") dim sdr as oledbdatareader = cmd.execute reader
whence it will show a list of all the currently "Online users" but i do not how how to quite refer to it?
I want to hook low level Mouse hook in vb, and after that I want to save the X-axis, Y-axis and clicks(Right/Left) into database for later use or automation..But I don't understand that how should I save the X-axis, Y-axis and clicks into a MS SQL databse and later retrieve them?
I have a form that is displayed, not by ShowDialog, but by setting its visible property to true. This is so it behaves like a dropdown.The form installs a mouse hook, using SetWindowsHookEx(WH_MOUSE, ...).
I detect if the mouse is clicked outside of the dropdown and if so, return 1 in my HookProc method and close the dropdown.The strange thing is, if I click outside of my drop down on to a textbox, the textbox still receives the mouse click, after my dropdown closes, even though it's been handled by my HookProc method.It gets stranger... If I click on a label or button, they do not receive the mouse click, as expected, after the drop down closes!
Using VB 2010, is it possible to capture all mouse clicks and determine what was clicked?We're trying to develop a small utility that will pop up context based menus to fill in application forms and common strings for terminal sessions.Basically, whenever I middle click I want my app to determine if the window was an occurance of PuTTY. If so, check the titlebar for certain strings and send keystrokes to that window based on the titlebar text.If VB 2010 can't do this, what should I be looking for? Will VB6 apps do the job? Will they work on a Windows 7 PC?
I have a form, that acts like a drop-down, that I display non-modal. I attach a mouse hook to the form to determine when the mouse is clicked out of it, so that I know to close it - by setting Visible = False.
Because I want the HookProc to handle the last click, I can't dispose the Hook or my Dropdown until I'm sure that my event handler has returned to the HookProc.[code]...
I need to write an application that can validate wether or not a proper process was followed based on information that was entered into another .NET appliction. Basically, I need to be able to intercept a mouse click on a button in another application so that instead of submitting the data it triggers my validation code then cancel the action if need be.
We do not have the code to the other application. I have everything I need perform the validation. The only thing I don't know how to do is intercept the mouse click on the button control of the other application. Can some one show me how this is done?
I'm attempting to intercept and interrupt mouse events. Lets say I wanted to disable the right mouse button down event, or even the mouse move event. I haven't been able to figure out the interrupting part.
I am using the (I assume pretty widely used) following code for Global Hooking of the mouse.

Trying to convert my home app from vb6 to .net but have a problem. I am using the code in the tut by Paul Kimmel but it is returning Err.LastDllError = 126. I am using this code as posted on Win7 and VS2010. KeyboardHandle is retuning 0 but Im not sure which part of it is the problem. There is a lot of new stuff there for me.
I have tried repeatedly to use a For Each Next statement inExcel 2003. The intent of this is to ititerate through a predefined selection of cells and set the value of the cell 3 columns to the right based on the value of the cell in the selection.
The latest code I have tried to use is the following:
Where SR is the active sheet. (I have only been introduced to VBA and code language for a few weeks, so I am learning as fast as I can. Please excuse my ignorance!)When I get to the 'If x.value' line I get the type mismatch error. I have tried to set my "each" to variant variable types and my "collection" (or selection as it were) to different variable types and constantly I am getting this same error regardless of my efforts.
I am searching for interger Id in a database using SELECT statement to search for the BranchId, I am passing this Interger Id to StrSQL which is defined as a string. I know that this is wrong but I do not know how best to do it.
I have a project in VB6, when I am executing this project locally it is working fine, when I am trying to execute it remotely it is giving the error like "RUN TIME ERROR 13, Type Mismatch"
I have a program that u record your clicks then you press a button (Ctrl + E) then it plays them back. What I want is for Ctrl+E to stop them, It would work but it seems like its being overpowered by the mousemoving and clicking. The keyhook did already work before I started on the playback part.

I have several windows open: VB, IE, Explorer... If I happen to close one accidentally, or on purpose, and reopen it, the buttons on the task bar are all messed up. I get used to them one way and I am constantly switching between the windows.Here is my question: Would I be able, in VB, to 'hook' the taskbar and be able to rearrange the buttons?I have no idea what to search for in Google. I happened upon a program once a while back, A REAL LIFE SAVER!. I could just click and drag the buttons using that one.
Please see bottom edit for where I am currently at I have created a pivot table that works fine when the pivot cache is defined as:
Dim ptCache As Excel.PivotCache = mainHighway.PivotCaches.Add(SourceType:=Excel.XlPivotTableSourceType.xlDatabase, SourceData:=mainHighwayData.Range("a1:v7500"))
My problem is that the number of rows changes from day to day, so I figure out the number of rows in the worksheet and then use that in my pivot cache:
Dim highlRow As Integer highlRow = mainHighwayData.Cells.SpecialCells(XlCellType.xlCellTypeLastCell).Row Dim ptCache As Excel.PivotCache =
[code].....
This returns the proper number for the last row, but once again throws the same type mismatch error.
Edit: I found out another bit of information, but I am not sure what to do with it. The pivot table works fine if the values in it are <= 65536, but the second I increase the range to 65537 I get the type mismatch that has been haunting me. This is true for all numbers >= 65537. I know that 65535 or there abouts used to be the last row in excel, but that is no longer the case. Also when I create the pivot table manually in excel I have no trouble and it has all of the data. I am using int or long, so it should not be an overflow or anything. Anyone have any thoughts on why VB.NET will not let me make a pivot table based on data with more than 65537 rows?
anything wrong with using datatype object and determine datatype in class property? I have a typed dataset and it has several integers columns that are null in the db. and when I make a call it throws exception.is there anythign wrong with setting it as object in my dataset.. changing the throw exception property to Nothing and passing it to my property as integer?
