Thanks so much for the advise, however using your code for the function I am still returning 0 rows. When I put the query directly into Access I return 8 rows. Again thanks so much for your thought and advise, I'll keep plugging along.

It's not obvious in the code. Either the query string your using directly in Access is different than the one generated by the code or the table name your passing in is different, or the database the app is using is different from the one your direct query is using.

Thanks once again for your thoughts. I ran console.writeline on both the connection string and the sql statement then using start run opened the database and ran the query that was placed in the output window. What I have found is when I take out the like and run an equal to where I get results in the datagridview on my form. It is becoming obvious that my problem has to do with like in the query which allows it to run in Access but not through the application. My next move is to try % as the wildcard not *. I sure wish I could use SQL Server but that is just not in the cards.
Again thanks for all your help.

Hi,
I have been trying to load the google toolbar in a custom web browser. But when it comes to the following line:
System.Reflection.Assembly.LoadFrom("C:\Program Files\Mozilla Firefox\extensions\{3112ca9c-de6d-4884-a869-9855de68056c}\components\googletoolbar.dll")
It says:
"Could not load file or assembly 'file:///C:\Program Files\Mozilla Firefox\extensions\{3112ca9c-de6d-4884-a869-9855de68056c}\components\googletoolbar.dll' or one of its dependencies. The module was expected to contain an assembly manifest."
I'd appreciate any help on how this can be done.
Thanks,
Ahmad

The last few months I have been developing a windows application for my company .The development was first implemented with Visual Studio 2005 Team edition ( 180 trial version ). The company decided to buy VSTO 20005 last month . Why am i saying all this ? Three months ago we installed to all our clients our application using ClickOnce , so that we could support them with frequent updates . But when i tried to publish some changes using VSTO , i got an error that "my certificate was not in my certificate store" . After a lot of search i realised that when you publish an application using clickOnce your manifest file is being signed with a test certificate , it doesn't matter if you choose to sign clickonce or not ( i was not choosing to sign my clickonce application ) , in your applications properties . That certificate not only is for testing purposes but IT EXPIRES after 1 year . So , after the certificate is expired , the users can still use the application , but you can no longer use the clickonce setup you created before. I tried to create a new certificate , publish again , and it all worked great . But , for my surprise , we can no longer support , send updates to our customers , because the first clickonce installation and the second one DO NOT HAVE the same certificate ! The solution that microsoft offers is simple .... Uninstall the old one and install the new one . Thankfully i found some articles how to create a new certificate , that expires in any years i want , but the big issue remains .
How to update the old installations with the new certificate . Sorry for my long message but i believe that such a good effort creating click Once installation should not face that kind of troubles .
You can create your own certificate using http://msdn.microsoft.com/library/en-us/seccrypto/security/makecert.asp
and exporting it using http://msdn.microsoft.com/library/en-us/seccrypto/security/certmgr.asp
A very good article about Click Once http://msdn.microsoft.com/smartclient/default.aspx?pull=/library/en-us/dnwinforms/html/clickoncetrustpub.asp
If anyone have any ideas how to overcome such an issue , without reinstalling everything , it would be much appreciated .
Thank you

Nope
We ran across the same problem - temp keys that expire in 12 months. The only solution that we could get to work was the uninstall process.
So the moral of the story - create a certificate BEFORE you start developing your clickonce deployed apps.
Sorry I know this does not help but at least you are not alone

I'm trying to make a gap-killer for the MP3 player I'm working on. Can anyone help me out with a way of getting the volume levels of an audio file? Basically I want to start from the end of a file and work backwards until the dB is at a certain level, and then trigger the start of the next song.
Simple crossfading would be easy enough, but it's a little too clunky for me. I hate cutting off the ends of songs that don't fade out.
Hopefully it works from both ends. Some of the songs I've got have dead air at the beginning too.
Thanks for your help.

Hi. I'm using Vb.net 2005 and need some way of allowing the user to select a folder and all files matching a certain extension (in this case mp3s) are then selected within that folder. I want to extract the abolute path, folder path and filename from each of the files in the folder. I already have used the OpenFileDialog class to select mp3s individually or by pressing ctrl + A to select all in the current folder, but i want to allow the user just to select a folder and all files are selected and using a for each loop iterate though all the files extracting the absolute path, file name and folder path. Can anybody help with this?

You can use a FolderBrowserDialog control to allow the user to select a directory (Its in the Dialog section of the toolbox near the OpenDialog control). Then in your code you can select the files that have a specific extension by using something like this:
Dim strMP3Files As String() <br />
strMP3Files = System.IO.Directory.GetFiles(strSelectedDir, "*.mp3")
Hope this helps.

Hey thanks alot.... It wasn't exactly what I was looking for but it got the job done by returning the absolute path of each of the files i was looking for. I just used a bit of string manipulation to satisfy my fileName field and got the folder path from the folderBrowserDialog.SelectedPath property. Happy times thanks alot

Hi Again,
Does anyone know how to implement the Alt-Tab function?
For example, I have my application running and I want the user to click on a button in my app which will return them to the previous running application without closing my app.
thanks,

I already told you there is no way to tell what the previous application or window was. You have to write hook code to track what the CURRENT window is and add it to a short list. WHen the current window becomes your application, you look in the pervious entry in the list to see which window HAD the focus.
Asking the saem question again and again will not change the answer.

Sorry, I wasn't intending on asking the same question, I understood your first reply and agreed with you.

Hello,
i use a web service that is written in php. this service provides, after login, a session id in its soap header. My question is who can i get and set this session id in my App?
I create a Proxy Class with the wsdl.exe.
Can somebody help??
Thank you
|
|
|
|
|
Hi,
I'll Assume that the class that inherits from SoapHeader called SessionHeader.
Dim oWS As New wsns.WebServiceName
Dim oSession As New wsns.SessionHeader
oSession.Session = "New Session..."
oWS.SessionHeaderValue = oSession
* wsns = WebService Namespace
Hope this helps ... and Enjoy

Hello,
first thank you. But my problem is not resolved. I will show you some code to understand my problem.
First the Webservice in PHP (This is ReadOnly Code, i couldn't change it)
function securityCheck($userid = null, $password = null) {
global $server;
$auth = new Authentication();
if (isset($server->requestHeader['Session'])) {
session_id($server->requestHeader['Session']);
} else {
$error = $auth->Login($userid, $password);
if($error != "") {
return false;
}
}
return $auth->IsLoggedIn();
}
function login($userid, $password) {
if (!securityCheck($userid, $password)) {
return new nusoap_fault('Client','',"Invalid userid/password",'');
}
return session_id();
}
The Login works fine. But then i get a Session ID back and this id need to be set in every request. My Problem now is to set the requestHeader.
Client Code
Dim Proxy As 'ProxyClass = New ProxyClass() (Proxy Class is autogenerate by wsdl.exe from VS2005)
dim sessionid as String = Proxy.Login(user, pwd)
-------------------------------------------------
dim test as String = Proxy.OtherFunction
Here i get a exception 'No session startet'
|
|
|
|

Hi,
I am not sure exactly about the code, but try to look inside your php code to find the function that return the message 'No session startet', check the condition that triggers that message, if the variable in that condition is readonly (not a public, webservice enabled variable) and you have no right to change the code then it will be so hard to solve the issue 
Good luck

im using window xp pro and visual basic express edition

i Suggest you Download the latest Security Patches, and you should get your self a good antivurus and scan your system unistall visual basic express edition and install it after all the scanning and installation of service packs/security patches. when something happens like that there is a worm.
Hope it helps

Hi,
It seems you need to get a single value from the selected row, if this is what you want please try the following snippet:
If IsDBNull(dg.Rows(e.RowIndex).Cells(0).Value) Then
TextBox1.Text = "N/A"
Else
TextBox1.Text = dg.Rows(e.RowIndex).Cells(0).Value
End If
* dg = DataGridView
Note: Change 0 to the column index that you want to read from!
hope this helps
