Unable to open DLL files

4 posts in this topic

Hi 

I am trying to open a dll using DLLOpen, however everytime i try to do so the function fails and returns -1 result. 

I have the dll in the same folder as the auto it script. 

Local $hDLL = DllOpen("C:\Users\310255155\Downloads\COMMGvv2\commg.dll")
DllCall($hDLL, "int", "MessageBox", "hwnd", 0, "str", "Some text", "str", "Some title", "int", 0)
DllClose($hDLL)
MsgBox(0,'result',$hDLL)

Using nirsoft's free DLL Export Viewer @ http://www.nirsoft.net/utils/dll_export_viewer.html, I could not find the export function, "MessageBox" in the "commg.dll" file.

To dllcall a message box, see the  _WinAPI_MessageBoxIndirect function.

First, look up _WinAPI_MessageBoxIndirect in the AutoIt help file and try the example, then;
Secondly, open the include file, WinAPIDlg.au3, and look at the actual workings of the _WinAPI_MessageBoxIndirect function.
You'll see "MessageBoxIndirectW" is the export function used from the "user32.dll" file.

Note : The return values of  the _WinAPI_MessageBoxIndirect function is the same as the return values of  the MsgBox function, which depends on which button is pressed in the message box.

      Hi all,

      I am having a little trouble with ‘GUICtrlSetResizing’ an hoping someone could push me in the direction of best practice.

      I have a basic GUI created to a set size with the enabled abilities to resize it:

      GUICreate("Test", 500, 450, -1, -1, BitOR($WS_SIZEBOX, $WS_MAXIMIZEBOX, $WS_MINIMIZEBOX))

      Inside this I have an image and label:

      GUICtrlCreateLabel($Image1StampInfo, 10, 395, 480, 20, $SS_CENTER) GUICtrlCreatePic($TheImage, 25, 25, 450, 350)

      Using:

      Case ($GUI_EVENT_MAXIMIZE or $GUI_EVENT_RESTORE or $GUI_EVENT_RESIZED)

      I activate:

       
      GUICtrlSetResizing($TheImageBox, $GUI_DOCKAUTO) GUICtrlSetResizing($Image1Stamp, $GUI_DOCKAUTO)

      This works fine with the image but not with the label – the label after a bit of resizing seems to get stuck in different places in the GUI as if the $GUI_DOCKAUTO has not worked properly.

      So 2 questions if I may. 

      1)    Have I used $GUI_DOCKAUTO incorrectly for use with lables?

      2)    I am happy to manually set new sizes dynamically but how? I can get the size of the window with ‘WinGetPos()’ but how do I set new size parameters for the ‘label’ and ‘image’?

      Thank you in advance.

      Good evening guys ( almost good night here in Italy )  
      How are you? Hop you're fine  
      I'm trying to do a Login Form ( I did, but I'm missing something in the management ), that allows the user to login when the script is launched, and, when the main GUI is opened, the user can Logout and Login with another username and password.
      The username and password "checking" I do is done by a text file, which in there are username and password, crypted through _Crypt_EncryptData().
      The "issue" I'm having at the moment, is to manage the Login form when the user hasn't already done the login, and so, the main GUI is not visible, but is created...
      I create the main GUI after the Login form... I tried with WinActive, WinGetState, but nothing changed ( even at the first Login, the script says ( through a MsgBox ) that the Win does exists ( or is active... ) and, as I want, it is not shown again...

      I really don't know If I missed something, or, I don't know...
      I'm going crazy for this thing...
      If someone could help me, I'd really appreaciate it!
      Thanks for the reading

      Hello, 
      I'm wondering if it is possible to read a radio button off a GUI running by another program? 
      Someone created these Outlook emails that when open appear to be in a GUI format. I could easily come up with a way of navigating these fields by using tab inputs, and then copying specific fields that I need. However there is a spot on the form that has 4 choices of radio buttons, asking for what the status of the task is, and I have no idea how to store which one of these was pressed. 
      End game is to be able to go through thousands of these forms, take input from specific fields from this GUI form in outlook and copy into cells in an excel spreadsheet. I believe I could create a script to do everything I need, if I could just obtain the value from which radio button was pressed.
      Any advice on how to obtain which radio button was press in this outlook form would be appreciated.
      Thanks,
      If I knew VBA better Outlook might have its own functions for figuring this out.
       
      Example:

      In this example I'd want to be able to know that the 2nd or Assigned radio button was selected. Only 1 button is able to be selected at a time. I'm assuming the way to do this would be to tab through the form get to the first box and then run some command to check if pressed then if no, keep checking till I find which of the 4 were pressed.

      Good morning guys
      How are you? Hope you're fine
      I'm doing some field checking...
      Can you suggest me something? Something like: If the user doesn't prompt anything in a field, MsgBox and focus on the "blank" field, else, keep up with the script.
      I thought on a nested If...Else, but I have something like 10+ edit to control...
      Thanks guys! 
      EDIT:
      And I would like to know either how to retrieve all listview item ( 2 columns ) from a ListView...
      Column A|Column B
      abcd         | 1234
      bcda         | 1432
      How can I retrieve an array with abcd|1234|bcda|1432 ?
      Thanks

      I want the number in a file to be overwritten with the next number up each time a button is pressed. 
      So it is pressed once, the number '1' is written to the file. It is pressed again and the number '2' overwrites the first number.
      At the moment I get the number 1 written, but can't get it to overwrite. What I have so far:
      #include <ButtonConstants.au3> #include <GUIConstantsEx.au3> #include <StaticConstants.au3> #include <WindowsConstants.au3> #include <FileConstants.au3> #include <MsgBoxConstants.au3> #include <WinAPIFiles.au3> #Region ### START Koda GUI section ### Form=C:\Users\soulf\Desktop\CalcGui\RLCalc.kxf $Form1 = GUICreate("Form1", 615, 437, 426, 141) $One = GUICtrlCreateButton("1", 32, 72, 25, 25) GUICtrlSetBkColor(-1, 0xFF0000) GUISetState(@SW_SHOW) #EndRegion ### END Koda GUI section ### Func First ()     $fPath = "C:\temp\First.txt"     $fOpen = FileOpen ($fPath, 2)     $Counter = FileReadLine ($fpath)     $counter = $counter + 1     $fWrite = filewriteline ($fPath, $counter)     FileClose ($fpath) EndFunc While 1     $nMsg = GUIGetMsg()     Switch $nMsg         Case $GUI_EVENT_CLOSE             Exit         Case $One             Call ("First")     EndSwitch WEnd I tried a Do Until statement, but that just puts the numbers 1 to 5 in the file.
      Any help would be greatly appreciated!
