From MS VB 6.0, when i call MSFL_GetErrorMessage(..), I get the following error:

---

Error

---

The specified module could not be found.

OK

Many other functions work fine. Do I need a different version? I believe I am on version 9.1. of the SDK

I'm just trying to use the function as definded in MSFL.bas. I have only included MSFL.bas and MSFLUtil.bas, I have not referenced or included any other files. Thanks,

yeah, I am trying to run the MSFL_ErrTest in the MSFLUtil.bas file. when it tries to execute: strErrMsg = MSFL1_GetErrorMessage(iErr, strErrMsg, MSFL_MAX_ERR_MSG_LENGTH) is when the error comes up. thanks,

yes, i am having the same proble with the sample code (vbviewer). I added Call MSFL_ErrTest(-189) to the function Private Sub mnuFileOpen_Click() in frmMain, and the same error comes up. I am, however, able to open files and look at the data with the program. thanks,

umm, I get the feeling u didnt read my last post. My code snippet is to add the line: Call MSFL_ErrTest(-189) as the first line in the function Private Sub mnuFileOpen_Click() in frmMain of the example code, VIEWER.VBP using MS VB 6.0. Having done that, I get the error message everytime I hit file-open. I'm not programming anything new here, I'm just trying to call the MSFL_ErrTest(..) with a value. My 3 ideas are: #1 - It doesnt work on yours either #2 - There is something funny about my installation, and I'm calling an old .dll #3 - There is something funny about my installation, and the correct .dll can't find some ancillary file Please note, the program compiles and works fine. It is making many successful calls to the other functions and I can see my files, and their data. Thanks,

ok, we're on the same page. Now can we use the same .dll? Im using MSFL1_GetErrorMessage Lib "msfl91d" (..) Thanks,

Sorry, I'm not using the latest release of the MDK. The principle should be the same.

I know this is a very old thread, but I am having exactly the same problem, and am hoping someone can help. I am using the MDK with VB.NET. I converted the files myself from the VB sample, and I have almost everything working perfectly. The only function that I seem to be unable to get right is the MSFL1_GetErrorMessage function which returns "The specified module could not be found" everytime I try to call it. I have discovered that this means that my declaration of the function in MSFL.vb is incorrect. I have tried about 30 variations of the function declaration, and none of them seem to work. Can anyone help me with the correct function declaration from VB.Net? The irony is that I've managed to get all the other functions to work correctly, and so it is hard to work why this particular function is wrong. Here is the declaration I am using at the moment: Declare Function MSFL1_GetErrorMessage Lib "msfl91d" (ByVal iErr As Integer, ByRef pszErrorMessage As String, ByVal wMaxMsgLength As Short) As String I have tried : - changing the iErr parameter to Long and Short - making the pszErrorMessage parameter ByVal and ByRef. - making the pszErrorMessage a string and a StringBuilder. - having the wMaxMsgLength as a Short, Integer and even Long - changing the return type of the function from String to Integer to Intptr and even String Builder None of those changes have yielded success, and so I have run out of ideas.
