  • How can I debug an application crash in Win7 after it's happened?

    - by parsley72
    I have a Visual Basic 6 application that I've recently changed to use a couple of C++ DLLs I've written in Visual Studio 2008. The application works fine on my PC, but when we install it on one of our test PCs it tends to crash during shutdown - we see the Win 7 message "Your application has failed" or whatever it is. I know Win 7 stores data that can be used to analyse the crash. I've got the source code and .PDB files from the build so I should be able to use that, but I can't figure out where Win 7 stores the data from the crash. The Event Viewer shows the crash but doesn't have any data and the directory C:\Windows\Minidump doesn't exist. Where do the crash files get put?

  • Fix hard-coded display setting without source (24-bit, need 32-bit)

    - by FerretallicA
    I wrote a program about 10 years ago in Visual Basic 6 which was basically a full-screen game similar to Breakout / Arkanoid but had 'demoscene'-style backgrounds. I found the program, but not the source code. Back then I hard-coded the display mode to 800x600x24, and the program crashes whenever I try to run it as a result. No virtual machine seems to support 24-bit display when the host display mode is 16/32-bit. It uses DirectX 7 so DOSBox is no use. I've tried all sorts of decompiler and at best they give me the form names and a bunch of assembly calls which mean nothing to me. The display mode setting was a DirectX 7 call but there's no clear reference to it in the decompilation. In this situation, is there any pointers on how I can: pin-point the function call in the program which is setting the display mode to 800x600x24 (ResHacker maybe?) and change the value being passed to it so it sets 800x600x32 view/intercept DirectX calls being made while it's running or if that's not possible, at least run the program in an environment that emulates a 24-bit display I don't need to recover the source code (as nice as it would be) so much as just want to get it running.

  • Has anyone gotten VB highlighting to work in Emacs23?

    - by akoumjian
    I have found and installed the visual basic mode for emacs. It seems to be loading on emacs startup and the VB mode loads when I open a *.bas file. The code is not highlighted at all, however. I'm using Emacs23, tried it with 21 and saw no difference. Background for the curious: I am rewriting a set of codes from VB to Python. The syntax highlighting will make it much easier for me to see what's going on.

  • Vb.exe performance time

    - by vinodacharyabva
    Hi I am running a vb.exe through automation. In exe I have return a code which takes a data from database and saves that data into file. I ran that .exe for the first time. It took 1 mins. For testing baseline I called same .exe 5 times one after the other. But it took nearly 10 mins to generate. My question is if it takes 1 min for 1 report to generate then it should take 5 mins to generate 5 report but why it is taking 10 mins (more than the double). Is there any problem while calling a exe one after the other?

  • How to preselect Administrator when running an application using ShellExecuteEx with verb "runas"? (

    - by Xinxua
    I have an application which runs another application (mine) using the WinAPI "ShellExecuteEx" with the verb "RunAs" so that the other application should start with "Administrator" credentials. My OS is Windows XP. (Do not bother about other operating system, as I have specific code in place) The only problem with this thing is that the "Current User" comes preselected. I want it to be the "Following User" with Administrator selected. How to do this?

  • Difference between Resume and Goto in error handling block

    - by Rich Oliver
    I understand that in the following example a Resume statement should be used instead of a Goto statement. Sub Method() On Error Goto ErrorHandler ... CleanUp: ... Exit Function ErrorHandler: Log error etc Err.Clear 'Is this line actually necessary?' Resume CleanUp 'SHOULD USE THIS' Goto CleanUp 'SHOULD NOT USE THIS' End Sub My question is what difference is there in the execution of the two?

  • How do you verify that 2 copies of a VB 6 executable came from the same code base?

    - by Tim Visher
    I have a program under version control that has gone through multiple releases. A situation came up today where someone had somehow managed to point to an old copy of the program and thus was encountering bugs that have since been fixed. I'd like to go back and just delete all the old copies of the program (keeping them around is a company policy that dates from before version control was common and should no longer be necessary) but I need a way of verifying that I can generate the exact same executable that is better than saying "The old one came out of this commit so this one should be the same." My initial thought was to simply MD5 hash the executable, store the hash file in source control, and be done with it but I've come up against a problem which I can't even parse. It seems that every time the executable is generated (method: Open Project. File Make X.exe) it hashes differently. I've noticed that Visual Basic messes with files every time the project is opened in seemingly random ways but I didn't think that would make it into the executable, nor do I have any evidence that that is indeed what's happening. To try to guard against that I tried generating the executable multiple times within the same IDE session and checking the hashes but they continued to be different every time. So that's: Generate Executable Generate MD5 Checksum: md5sum X.exe > X.md5 Verify MD5 for current executable: md5sum -c X.md5 Generate New Executable Verify MD5 for new executable: md5sum -c X.md5 Fail verification because computed checksum doesn't match. I'm not understanding something about either MD5 or the way VB 6 is generating the executable but I'm also not married to the idea of using MD5. If there is a better way to verify that two executables are indeed the same then I'm all ears. Thanks in advance for your help!

  • Can I destroy a class instance even if there are still references?

    - by DR
    For debugging reasons I want to destroy a class instance which still as references. Is that possible? It doesn't have to be elegant or stable, because this'll never end up in production code. To clarify: Public Sub Main Dim o as MyClass Set o = New MyClass //o is created, one reference DestroyObject o //Class_Terminate is called and the object destroyed //Further code, not using o End Sub //Possible runtime error here (don't care) Is that possible? One way would be to call IUnknown::Release to manually decrease the reference count, but how do I now how often I must call it?

  • Opening vbp Visual Basic Project

    - by Roman
    I have got some old sources written in Visual Basic. There are *.bas, *.cls, *.frm and *.vbp files. As I understand, vbp is a project file. But I cannot open it with my Visual Studio 2008. What version of VS should I install to open *.vbp file? Google says it is Visual Studio 6, but I am not sure and I cannot find Visual Studio 6 for downloading. Is there any publicly available free edition of Visual Studio 6 with Visual Basic? Thanks.

  • Why the difference in speed?

    - by AngryHacker
    Consider this code: function Foo(ds as OtherDLL.BaseObj) dim lngRowIndex as long dim lngColIndex as long for lngRowIndex = 1 to ubound(ds.Data, 2) for lngColIndex = 1 to ds.Columns.Count Debug.Print ds.Data(lngRowIndex, lngColIndex) next next end function OK, a little context. Parameter ds is of type OtherDLL.BaseObj which is defined in a referenced ActiveX DLL. ds.Data is a variant 2-dimensional array (one dimension carries the data, the other one carries the column index. ds.Columns is a Collection of columns in 'ds.Data`. Assuming there are at least 400 rows of data and 25 columns, this code takes about 15 seconds to run on my machine. Kind of unbelievable. However if I copy the variant array to a local variable, so: function Foo(ds as OtherDLL.BaseObj) dim lngRowIndex as long dim lngColIndex as long dim v as variant v = ds.Data for lngRowIndex = 1 to ubound(v, 2) for lngColIndex = 1 to ds.Columns.Count Debug.Print v(lngRowIndex, lngColIndex) next next end function the entire thing processes in barely any noticeable time (basically close to 0). Why?

  • Help! Getting an error copying the data from one column to the same column in a similar recordset..

    - by Mike D
    I have a routine which reads one recordset, and adds/updates rows in a similar recordset. The routine starts off by copying the columns to a new recordset: Here's the code for creating the new recordset.. For X = 1 To aRS.Fields.Count mRS.Fields.Append aRS.Fields(X - 1).Name, aRS.Fields(X - 1).Type, aRS.Fields(X - _ 1).DefinedSize, aRS.Fields(X - 1).Attributes Next X Pretty straight forward. Notice the copying of the name, Type, DefinedSize & Attributes... Further down in the code, (and there's nothing that modifies any of the columns between.. ) I'm copying the values of a row to a row in the new recordset as such: For C = 1 To aRS.Fields.Count mRS.Fields(C - 1) = aRS.Fields(C - 1) Next C When it gets to the last column which is a numeric, it craps with the "Mutliple-Step Operation Generated an error" message. I know that MS says this is an error generated by the provider, which in this case is ADO 2.8. There is no open connect to the DB at this point in time either. I'm pulling what little hair I have left over this one... (and I don't really care at this point that the column index is 'X' in one loop & 'C' in the other... I'll change it later when I get the real problem fixed...)

  • Time is updating when a form is not even running

    - by onaclov2000
    A co-worker of mine had downloaded a vb example project a while back to see how to make a call or two, he discovered it today again, and noticed that while sitting in the IDE the time/date is updating automatically when the entire project is not even running. How does this work, we looked around for code but can't find anything giving it away. Any ideas?

  • How do I pass a struct (or class) message back and forth between a C# service and a separate VB 6 ap

    - by grantjumper
    I need to pass data between a c# service and a running vb 6 application, considering using Windows Messaging. How do I pass the data back and forth between a C# service and a running vb 6 application? Shortened sample of the data I am passing back and forth is below: namespace MainSection { public struct Info { private int _Id; private string _TypeCode; private float _Calc; private DateTime _ProcessDate; private bool _ProcessFlag; public int Id { get { return _Id; } set { _Id = value; } } public string TypeCode { get { return _TypeCode; } set { _TypeCode = value; } } public float Calc { get { return _Calc; } set { _Calc = value; } } public DateTime ProcessDate { get { return _ProcessDate} set { _ProcessDate = value; } } public bool ProcessFlag { get { return _ProcessFlag} set { _ProcessFlag = value; } } } }
