How to retrieve the particular column row to the text box?
I mean how to display it in textbox?
The column has got different rows.
The code I wrote in vb net is :
cmd = New SqlCommand("select ida from Issue where aname='" + TextBox3.Text + "'", con)
In the above line I compare the textbox3 data in the table.
And if the data matches then it should display the ida column record that matches with aname row record to textbox4.
I am doing something wrong for sure as I wrote it in this way:
textbox4.text=cmd.ToString.
The above line din't give any error and it din't show anything in textbox4 also.
So ,how to display it?

It looks like you have not executed the SQL cmd.
Something like this ...
Dim SQLrdr As SqlDataReader
SQLrdr = SQLcmd.ExecuteReader()
While SQLrdr.Read
debug.print (SQLrdr("ida"))
End While
SQLrdr.Close()
SQLrdr = Nothing
Check on other ways to execute SQL.
Look at DataAdapters and ExecuteScalar

I would like to automatically include the latest compile date and time in my .exe. I am using Visual Studio 2010. Is that possible?
|
|
|
|
|
Not directly, but it's already there. Look at the LastModified time on the resulting .EXE file in your BIN folder.
|
|
|
|
|
There is no equivalent for the C preprocessor capabilities for including the compilation date/time, however you could look at the creation or modification datetime of the EXE file. I suggest you read up on Application.ExecutablePath and FileInfo.

Hello,
I have an urgent task that requires to write an application in VB .NET with features like IVR and DTMF. I am running out of time so I found and SDK called Ozeki SIP SDK in order to get ready with the task. I am doing the things provided by the following page: http://www.voip-sip-sdk.com/p_331-vb-net-dtmf-ivr-voip.html[^]
What do you think will this tool be relevant for my task?
Please share your opinion.

without testing it myself it would appear that it could do what you require of the SDK, the only thing left to do is test it!

you're good, i learned it in only 1 hour.
i created a server and client program.
the server keep listening and any single text send from client, i write it in textbox.
and the client mark the server IP and can only send text.
nah i got question, chatroom is something that everyone sees every word.
so if server receive text from 1 client, server should loop and send it one by one to client?
btw, thank you very much.

Whehe, that means that you are good at it - not me.

Yup, or store it all in a central location (but than you'd have a server again).
You could "promote" one of your peers to "act" as a server for the duration of the chat. All the clients would have to agree on who gets promoted, but it should generate less traffic than having each client update each client.

I am facing a certain problem. I am trying to delete a certain file programmatically that resides in the system32 folder (malicious file). When i try to delete it using the kill statement an error message shows that says Access Denied as the file is being used by another process. When i searched i found out the that winlogon.exe uses this executable. How can i remove this handle programmatically. Any ideas and suggestions would be very helpful.

WinLogon cannot be unloaded, and you cannot unload anything that's being referenced by it. You could have Windows remove the file "after" a reboot (it does this before it starts the shell, meaning that WinLogon will not yet be in use)
That's not recommendable though; the infected file will have replaced the original, and deleting it will corrupt your system. Unless you can put back a file that's not infected, best idea is to not touch it.

No, just a new malicious file has been created in the windows/system32 folder.When i try to delete that file it shows file in use . and this file is being used by the winlogon.exe process. how can i delete this file programmatically.

How did you determine that it's a "new" file?
Files can only be deleted when they're not in use, and you can only remove it after a reboot and before logon, as described before. (Simple explanation, I cannot throw away your mug if you're still drinking from it, since it's in use)
WinLogon does not load random files. If the file is in use, it counts as a dependency. If WinLogon is started without the dependency, it will simply fail.
"Old" file's would be "corrected" by putting back a copy from a previous restore-point, or by copying back the original file from the setup.

how to create a menu items on a form you had?... hmmm...
hermaine...",)
|
|
|
|
|
Do you wish to create a menu on your form?
In the toolbox, in the menus & Toolbars section, drag and drop a MenuStrip onto your form then start filling in your various menu options.
Double clicking the finished menu will create a a Private Sub menu item click event where you place the code to call the various menu item request calls.
Hope this helps

Depends on the way that the dictionary is written to file/the structure of that file. Without any additional info, I'd say "deserialize".
haneeno wrote: how can write (fixed width code) in information retrieval via vb.net?
By reading the file as text, and copying the content of that subpart of the string. See the System.IO namespace and the examples on MSDN.
haneeno wrote: how can write (blocking code) in information retrieval via vb.net?
All code is blocking, if you want async code you'll need to define a thread.

Can sombody help me make a startup window that fades in and out?
|
|
|
|

I suppose there may be another way to achieve this, but ....
If the information to be displayed on the Startup Form is to remain static (ie not changing) may I suggest using an image transition effect to achieve your "Start Up Fade".
First create a graphic of your "startup page information" which will be displayed in a picturebox control.
Then I would add a new winform or splash to your project, set FormBorderStyle to None, add a PictureBox the size of the form that will load the page graphic (Startup Image) you created, then when the new form loads on application start, call the image transition effect, cycle through the fade in, small delay then fade out then close the window.
I believe the CodeProject has a project that demonstrates how to implement a simple trasition on images in vb.net which could be used to create the fade in fade out process.

Hope this helps
