I'm having problems using the Web Browser control in Vista. When I go to a page with any type of Flash Content it won't load. I went to the Flash plugin page and it said 64bit web browsers are not supported. This only happens on the Web Browser Control that I am programming with. If I just open the Microsoft Internet Explorer 7 it works just fine and has no problem loading Flash content. If I can't display Flash content it's a big problem so if anybody can point me in the right direction it would surely make my day.
Thanks In Advance
PS I have tried both the com version and the one that comes with VB.Net
both will not display Flash Content
I am using Vb.Net 2008 Express
Operating System Vista Home Premium Service Pack 1

USER_EMPL_NO F2999999
USER_LOGIN FVCJBN01\F2999999
USER_NAME Lisa Lopes
USER_CO_CODE 80
USER_BRN_CDE 189

What have you tried so far? Searched on Google?
|
|
|
|
|
first detect the communication port which u r connected mobile to the pc.
open the communication port.
and send commands.
to send SMS:- at+cmgs="+919000234140"<vbcrlf>
>hi <ctrl+z>
to dial number :- atdt+91900234140;<vbcrlf>
** note : the above commands are not suitable for all mobile manufactures.
there may be a change in the command, so search the AT commands list in internet(recommended GOOGLE).

Hello to everyone.
I have the problem with my experimental, tutorial project (made in VB.NET) of syncing Microsoft SQL Server Standard Database (it is server) and MS SQL Compact DB (it is client). The synchronizer is based on MS Sync Framework (MSF) API classes.
The problem happens with SyncAgent Class. I created the class mySyncAgent which inherits the SyncAgent class. In the mySyncAgent I just gave settings for Local and Remote Providers (connection strings, sync type, direction etc - everything like it was described in MSDN tutorial example).
Now I try to make synchronization by using the method: statistics = myAgent.Synchronize where statistics is the instance of SyncStatistics class, and myAgent is the instance of SyncAgent class.
When I do it, the program stops to run and VB.NET compiler shows me the following error>: Method not found: 'Microsoft.Synchronization.Data.SyncException Microsoft.Synchronization.Data.SyncExpt.AnotherSyncInProgressError(System.String, System.String)'.
It is very strange error and I don't understand what causes it. First, there is no synchronization.data.syncexception library - it exists in another, older version of that class - but I can say for 100% sure that there is no conflict of versions generally in this project - so this is not a cause, not a reason. Anyway, the problem is not because of the missing method (there is a new one, in a new version), but the fact that Another Sync is in Progress. But I didn't call synchronization anywhere else except this method "statistics = myAgent.Synchronize" (I checked if there are other callings of .synchronize - there are no calls; neither in constructors nor anywhere else). I was doing debugging with tracing of variables, parameters of objects. This is the content of this variables at the run-time error.
myAgent:
*RemoteProvider: Everything is OK (like I set) - i.e. Connection Strings, SyncAdapters etc
*LocalProvider: Here is the most interesting stuff that (maybe) calls this error. There is subproperty "ClientID" which contains 2 properties called "Message" with the same content:
"Method not found: 'Microsoft.Synchronization.Data.SyncException Microsoft.Synchronization.Data.SyncExpt.AnotherSyncInProgressError(System.String, System.String)".
And property StackTrace of ClientID contains " at Microsoft.Synchronization.Data.SqlServerCe.SqlCeClientSyncProvider.BeginTransaction(SyncSession syncSession)
at Microsoft.Synchronization.Data.SqlServerCe.SqlCeClientSyncProvider.get_ClientId()"
What could be the cause of this problem? Could it happen because the connection to localProvider (based on MSSQL Compact 2005) is not open (by some reason)?
If anyone could just tell me where the possible mistake could be???
Thank You
Igor

Hello All,
How can I search for a particular file inside the .zip file?
Thanks in advance
Amit
|
|
|
|

Check out the System.IO.Packaging namespace (.net 3.0 or 3.5). It allows you to create zip files so I'm guessing if there is a way it will let you do it.

this service is running under "LOCAL SYSTEM" SO WHY it doest not work?
if i provide the username and password than it works why ?
local system account is the most priviliged account in service context
so why it is like so ?

The proxy server is telling you that authentication is required and not the service.

hi..,
i think your pc connected through proxy,
do this
go to internet explorer -> tools-> internet optons->
go to connections tab--> lan settings -> in the popup box unchech all the check boxes. close the IE
run your application
this may help U....

The proxy is telling you that the LocalService account is not authorized to use the proxy. You have to supply the proxy with credentials, specifying an account that DOES have access to use the proxy.

Hi - I have a VB.Net app that controls several devices - including a servo on a USB/Com port using a VCP - I am adding another device with another USB/Comport VCP driver and my vb.et program will not send the write buffer contents to the port, but does not throw an error but hangs on the next read.
I have tested the interface and device (a USBI/O24R board) using hyperterminal and the device and ports work fine.
Lots of time searching for a similar problem - no joy - so here are a few questions.
Is there a limit on how many USB/Serial (virtual COm Port) emulators in a system. Is there a problem with high com munbers (I started at 17) - but I should point out that I move the USB/Serial port to com2 with the same results.
Is there a problem with the USBI/O24R driver ? I have had a few emails with the chip supplier but no help yet except try getting to a lower com port - no results.
Below is an extract of my test code . . .
I added the GetSerialPortNames to see what was happening - POrtmon shows tthe name of the port and the open/close and a single write of "0A" but none of the data string. No change when the VCP was forced to Com2
Thanks for the help
Bob

Hi all,
Any help with this one very much appreciated (I've spent weeks on it (on and off) and it is driving me mad...)
I have a need to retrieve and set the raw values of a joystick (not the calibrated values returned normally). The code is written in VB.NET and uses DirectInput.
My code works at present but returns calibrated data (so a range of 0 - 65535). A snippet of the code below:
My question is: How can I retrieve (and set) the raw data values returned by each axis?
My reading did point me at IDirectInputDevice8::SetProperty, and to use the DIPROP_CALIBRATIONMODE parameter - but I can't work out how to do this in vb.net.
(In case anyone is wondering why I would not use the control panel to calibrate a joystick - I need this code as the program will manually 'calibrate' the pots out of a joystick on a DIY motion platform simulator we are building - and we wish to use joystick pots as the feedback mechanism).
Again - thanks in advance to anyone that can help.
Dim devices As Microsoft.DirectX.DirectInput.DeviceList
Dim device As Microsoft.DirectX.DirectInput.DeviceInstance
Dim Joystick As Microsoft.DirectX.DirectInput.Device
Dim JState As Microsoft.DirectX.DirectInput.JoystickState
'Get all the devices of type joystick
devices = Microsoft.DirectX.DirectInput.Manager.GetDevices(DeviceType.Joystick, EnumDevicesFlags.AllDevices)
'Do we have at least one Joystick?
[...]
devices = Microsoft.DirectX.DirectInput.Manager.GetDevices(DeviceType.Joystick, EnumDevicesFlags.AllDevices)
[...]
'Move to the first
devices.MoveNext()
'Now get the first device.
device = devices.Current
'Now get joystick handle to the device
Joystick = New Microsoft.DirectX.DirectInput.Device(device.InstanceGuid)
'Tell the joystick to behave itself as we want it to.
Joystick.SetCooperativeLevel(Me, CooperativeLevelFlags.Background + CooperativeLevelFlags.NonExclusive)
Joystick.Acquire()
Joystick.Poll()
JState = Joystick.CurrentJoystickState
Joystick.Poll()
JState = Joystick.CurrentJoystickState
TBJoyX.Value = JState.X
TBJoyY.Value = JState.Y

For others, in case this is useful in future, I didn't need to calibrate the joystick (or get to its underlying RAW values). The reason is that I discovered that 'modern' USB joysticks auto-calibrate...

I've been trying to deal  with bitmaps in DPX format (a motion picture format). After ages of trial and error I stumbled upon some information in the help files that GDI+ would only  support several standard formats (like JPG, BMP etc.). Still being a newbie I assume now that all of the useful image classes obviously don't work with a dpx-file...  and I'm close to giving up the idea of direct pixel access through VB.
Can one of you experts in here tell me if my assumption is true or if there are other ways to open (and work on) an image file which is not in a mainstream format?
Thanks
Michael

True! You have to either find a library that does support the format, or create your own.
Michael Schäuble wrote: and I'm close to giving up the idea of direct pixel access through VB.
Yep! No direct pixel access is possible, with any speed anyway, because VB.NET still doesn't support pointers. You can use C# to create a library that does this for your VB.NET app though.

Too sad, but thanks for making it clear. Unfortunately I'm not experienced enough to write my own libraries and not a professional programmer, anyway.
What do you think about involving third party solutions like GraphicsMagick (open source) for the graphics part? Like generating command-line strings and calling gm for the transformation? Or would that be too clumsy....

Using command line utilities will be very clumsy. Find a library that does this natively, either COM or .NET-based.

Is possible to create an XmlDataSource that has 50 columns merge an sql database with 14 columns into and force the other 36 columns except and false or any value I want with vb.net

Sure. Why would you want to? XML is NOT a database despite every newbie's attempt at making it behave like one.

While I'm sure I could easily work out something to do this, I was wondering if there was a function that would add an array of bytes to the end of an existing byte array.
Specifically, I am working on a project where a method takes a byte array as a parameter, where the byte array contains more than just a converted string.
Original C/C++ sample code:
unsigned char buf[10];
int len = 10;
buf[0] = 9;
buf[1] = 76;
sprintf((char*)&buf[2], "%d", groupnum);
I'm sure the answer is obvious, but it's just not hitting me in the face right at the moment.
(For those interested, this is an example from Avaya's "IP Office TAPI Link Developer's Guide" to build the parameter block for the lineDevSpecific function of TAPI 2.x. I'm working on the project in VB.NET using JulMar's ATAPI.NET wrapper. I'm having another issue with the function call to use the byte array, but that's another matter entirely.)
