    - Cancelling change in ColumnChanging event I wire the ColumnChanging event on a datatable. In the ColumnChanging event handler, I validate the change. If the validation fails, I would like to prevent the change from occuring. Right now I call e.Row.CancelEdit(), where e is the DataColumnChangeEventArgs. It seems like even if I call CancelEdit, the ColumnChanged event fires anyway.

    - changing he GUID of an application Is there a way to regenerate the GUID of a VB .Net application w/o writing code (e.g. w/in Visual Studio tools). I have a Shell that I use initially to build similar applications. I make a copy of the Shell to start with but it contains the same GUID. I know I can change the GUID manually by going to the project's property and I can keep track of the GUIDs I use.

    - string as out parameter Is there any way to allocate space from managed code on unmanaged memory and to write to that memory I tried to do so, but i have no idea how i can do that. I think it would be solution to my problem. Right now ,i managed to pass that array of strings to C++ client, by initializing LPWSTR* ppCustomString in C++ client, like this: **ppCustomString = new LPWSTR[noOfStrings]; This is not good. Neither i do know how many strings will be returned, nor what is their maximum number. But in this case, i must initialize LPWSTR* parameter and than pass it as parameter and than i will be able to see some results. Right now, trouble is next.

    - Interop to VB DLL fails to load Ok, I looked up the GUID for the typlib using oleview, found that guid in the registry, and deleted the entire entry, then recompiled the VB dll(which registers it in the process). I removed the references in the .NET project, cleaned, re added references, rebuilt. Now it works. So thanks alot. I just hope it doesn't suddenly stop working again.

    - Accessing a password protected file. Hi; It looks like LoginUser using LOGON32_LOGON_NETWORK, LOGON32_PROVIDER_DEFAULT does work for case (1) - thank you. For the others, it may be it cannot be done as NetUseAdd has lots of problems in this case (can't call same share twice, what if you delete an existing share that was already open). It's frustrating because the network can obviously do it using NetUseAdd but it's not exposed in a useable API. For the file://filename I was told by MS support that that is the same filename so that doesn't buy us anything. thanks - dave Tag: Common Language Runtime How to pass the datatype of map, struct from interop dll to Vb.Net application. .NET Development

F:\IMPORT\manpoll\FTP\misc now. here where the hard part comes (for me) and this is why i used access.. As you can see these files are pretty much all the same. I have 58 of them, they update to the given location nearly 5 times a day. They conatin information on the configuration of our stores terminals. they are either configured as "Backup" or "Workstation" the only that can be set as backup is "02" and it NEEDS to be set as backup ALL other terminals MUST be set as "Workstation" I have to sift through these files everyday and try to catch the ones that do not meet those requirements, then I have to email the store and tell them whats what. So i need this page to return to me all the "REDFLAGS" if you will.. EXAMPLE: Store 22 has no BACKUP or STORE 22 Terminal 05 is wrongly set as backup I think you get the idea... also the the text itself in these files do not contain the store number, only the NAME of the file does... This might be an easy thing to do without access, I am not sure...

    - SerialPort class in non-overlapped mode You have very little hope of making this work reliably. Your user-mode program works at an entirely different timescale from the kernel mode serial port driver. The driver has the benefit of being able to be notified by hardware interrupts that keep the flow of data between the UART and the transmit buffer in the driver going. This take a few microseconds. Your user-mode program is subjected to the kernel's thread scheduler. It gets a "quantum" of CPU cycles, typically around 15 to 30 milliseconds. It has to compete with other threads that need cycles too. Even if your thread is the only one really doing anything, from time to time you'll see another thread getting and using that quantum. Meaning, your program will be dead for 15 msec or more. This gets worse as the system gets loaded heavier, losing 6 quantums (100 milliseconds) is par for the course. Using a baudrate based timer under circumstances like that is nothing but a good guess. To drive the point home: that's 5 orders of magnitude. Keeping DSR sync-ed with the data transmission is going to require writing your own device driver. That's all possible, you get the serial port device driver source code in the DDK. It is not going to be any fun. Not to mention that you'll also have to make this work on the other end of the line. You haven't explained why you need this kind of fine-grained control over DSR. If it is necessary to prevent buffer overflows or data overruns, you'd better start thinking about lowering the baudrate or get a more capable serial device.

LPSAFEARRAY *varlistOfFilesFoldersToImport // In

LPVOID pMapOfFileNameOrItemIDRevDwProps // Out

)

I am calling this method from Vb.net 2005 , so how to get the out paramater in vb.net application.

Thanks in adavance,

You'd use the ByRef keyword in VB.NET. I'd assume you'd have to declare the argument type "IntPtr".
