what i meant is, after the deployment, any changes to the original source code won't apply!
|
|
|
|
|

Well that's the weird thing, ANY changes to the original source won't apply..i re-compiled so many times but it keeps acting as the old code would!
It's like a fix code!
I don't get any compilation errors tho't

Are you sure you are using the correct binaries? I mean, the new assemblies do actually have the current date/time on them? The only thing I can think of is that you are getting the assemblies from an old directory, or you are looking in Debug or Release, when it is compiling to the other.
Have you tried deleting the bin directories in your project then getting it to rebuild the whole solution? That way at least you know that the files in the bin directories are new.
If it isn't any of the above, then I am not sure what it could be because I have never come across anything like this.
Do you want to know more?

also make sure that after u have compiled ur project u rightclick on ur setup project and select rebuild option.
if problem still exist try to remove the setup project from the projectlist and then add a new setup project.
Hope it will work.

Hi.
I'm trying to play an .AVI file from a .dll, but the mmioInstallIOProcA fails.
It returns NULL (eg. error)
The code is:
In module:
<br />
Declare Function mmioInstallIOProcA Lib "winmm" _<br />
(ByVal fccIOProc_4 As String, ByVal pIOProc As Integer, ByVal dwFlags As Integer) As Integer<br />
<br />
Public Function AsAny(ByVal obj As Object) As IntPtr<br />
Dim MyGC As GCHandle = GCHandle.Alloc(obj, GCHandleType.Pinned)<br />
'get address of variable in pointer variable<br />
AsAny = MyGC.AddrOfPinnedObject()<br />
End Function<br />
<br />
Public Const MMIO_INSTALLPROC = &H10000 'mmioInstallIOProc: install MMIOProc <br />
Public Const MMIO_GLOBALPROC = &H10000000 'mmioInstallIOProc: install globally <br />
Public Const MEY = &H2059454D 'This is the value of "MEY " run through FOURCC <br />
<br />
<br />
In form:
<br />
<br />

End Structure<br />
<br />
In function:
<br />
hInst = LoadLibrary("C:\test.dll")<br />
hRsrc = FindResource(hInst, "#101", "AVI")<br />
hGlobal = LoadResource(hInst, hRsrc)<br />
lpData = LockResource(hGlobal)<br />
fileSize = SizeofResource(hInst, hRsrc)<br />
<br />
Dim IODlgPro As IOProc<br />

<br />
Dim res As Integer<br />
res = mmioInstallIOProcA(MEY, AsAny(IODlgPro).ToInt32, MMIO_INSTALLPROC + MMIO_GLOBALPROC)<br />
Error comes here.... returns 0
<br />
'Play the AVI file <br />
res = mciSendString("open AVI.MEY+ type avivideo alias AVI parent " & ParentHandle & " style child", 0&, 0&, 0&)<br />
DisplayError(res)<br />
<br />
res = mciSendString("play AVI", 0&, 0&, 0&)<br />

Without further information, like what library your using and a link to it, and what line the error occured on, it's difficult to tell what the problem is.
But, looking at you Declares, my first guess would be that your not passing parameters to all these functions correctly. Without the documentation on the library, it's impossible to tell.

First thing is to go to
http://network.programming-in.net/downloads/rvpacket.zip
and download the file. file name is "rvpacket"
and then go to
http://winpcap.mirror .ethereal.co
and download "winpcap"
-----------------------------------------------------------------------------
the error is at line PacketQueue = checkPacketQueue(adapter)
im textbook programming this one and i don't have a Clue what I mean to say is in the book it told me to go to those two sites and download the DLLS that I would need to build and run this application I don't know what I have done wrong if you can please take a look and help if you can thank you

I have a string data field that I want to convert to Int32 that can contain negative numbers. When I run my code I keep getting an error.
What can I do to get this conversion to work?
Thanks, Anthony

Would you mind terribly showing us your code so we can see what you're doing. Without it, it's impossible to tell you what to do to get "it" to work.

Nevermind. I realized that my error was not the negative number, but rather that my value was a decimal and not an Int32.
Thanks

i want to build a project that
automatically encrypt/decrypt the incomming/outgoing packets in a LAN. It
would be by some hooking thing, build a network card driver or add an
additional layer on network layer. So can you please help me in building this
project by giving tips? you can help me in either ways:
if i want to build a hooking thing type which listen on all TCP and UDP ports
for data , automatically encrypt/decrypt the incomming/outgoing packets, how
can i do that?
OR
if i want to build network card driver, which automatically encrypt/decrypt
the incomming/outgoing packets in a LAN how can i do that? i have no idea
about writing a device driver.
OR
how can i write an additional later like a layer of NDIS protocol which
automatically encypt/decrypt the incomming/outgoing packets in LAN?
you can tell me the link to the source codes, examples, ebooks, books,
articles or tell me in your own way.
i will be very thankful to you as i am feeling so busted to write such type
of application in just in a week.
i am looking forward to you.

You're not going to do this in VB or VB.NET. Period. This is going to be a device driver project.
This is a project soley in the realm of C++ and the Winodws Device Driver Development kit. If you've never written a device driver, shelve this project now and learn. You're getting into a dark and not very well documented area of Windows development and you've got ALOT to learn before you tackle a project like this.

We've found that if you have logic checking the existence of a file and you don't have access to the folder, the logic simply comes back as not exists.
For example if there is definitely a file called test.txt on the H:\ drive root directory and we don't have access to that drive the following logic simply executes the else part of the logic.
if file.exists("H:\test.txt") then
msgbox("It exists")
else
msgbox("It does not exist")
end if
How can we check if we first have access to a specific directory or drive?
Any help is appreciated.

You just did. Since you can't see the object, you can't get your access rights on it either. If you try to get your rights to the object, Windows will come back with something like "We can neither confirm nor deny the presence of H:\, let alone your rights to it."

We found that the following code worked well.
Try
………
Directory.GetFiles("c:\test")
………
Catch ex As UnauthorizedAccessException
Msgbox(“Sorry you’re not able to access the file….. yada yada yada”)
End Try
Thanks for your assistance!

You might want to try asking a question we can answer. None here will "guide" you in creating an entire application, since that is way beyond the focus of these forums and beyond the capability of a forum for that matter.
If you have specific questions about problems your having, great! We can do our best to try and answer them. But a generic statement like "I wanna write an app." is not going to help you at all.

I have a standalone application written in VB.NET that uses an access DB. The application is portable and used by several users on differnet machines. I want to be able to sync the portable DB's with a master DB. Is Replication the only way? The DB's are password protected at present. I can think of a way using replication with JRO, but that seems a bit old hat now. Please help
