hi buddy..
wat prasad said is correct.. i don know vb.net, but im sending the vb code for this.. try it out..
Private Sub Form_KeyPress(KeyAscii As Integer)
If KeyAscii = 16 Then Exit Sub
End Sub
Private Sub Form_Load()
Me.KeyPreview = True
End Sub
The keyascii for CTRL+P combination is 16.. got it??
|
|
|
|
|
This doesn't make any sense. You say you want to disable the Ctrl-P keys in your application, but if you don't provide the shortcut in your app yourself, Ctrl-P won't do anything anyway??
Wait a minute....Is this a Web Application (ASP.NET)??

A text box contains text - if you enter numbers in it and assign to a numeric field, VB will do an automatic conversion, but what happens if the text contains characters other than numbers? Converting the text to value is always a good idea when assigning to number type fields.
And an empty string is not a null value...
Hope this helps

Meaning that my code is correct i just need to make some conversions.?and please can you pleae comment on myConnection and my indivisual buttons , where should i improve and what is safe. Advice.

i have managed to add data and save it, but whe i click on cmdPrevious
it show me this Error
"Row handles must all be relaeased before new ones can be obtained" hence this is a big database , did it save the record? and why that Error.
The code for First and Previous
Private Sub cmdPrevious_Click()
rrs.MovePrevious
If rrs.BOF = True Then
rrs.MoveFirst
End If
End Sub
Private Sub cmdFirst_Click()
rrs.MoveFirst
End Sub
and i get an Error when i try to Delete
"Either BOE or EOF is true or the Current Record has been Deleted Request Operation Requires Current record."
What suprises me is that i was scrolling through the recordset and i came across the blank record, so i was trying to delete it.Below is the code for delete
Private Sub cmdDelete_Click()
On Error GoTo DeleteErr
With rrs
.Delete
.MoveNext
If .EOF Then .MoveLast
End With
Exit Sub
DeleteErr:
MsgBox Err.Description
End Sub
Thank once more

the file you are choosing, may be corrupted or some sort of fragmentation must have occurred...
|
|
|
|
|
The icon file isn't valid. There are a couple of applications out there that do NOT generate the proper format for an .ICO file, though, I can't remember what they are. This problem has come up before. The users ended up using a different package to create their icons.

Please
1 - use meaningful headers. Hi..... doesn't cut it
2 - don't ask twice. Respond to one of the answers in your first post if you want to clarify or ask more
Now that you've described it, you just need to store the the filenames that have been selected before. It's a type of MRU, as far as I can see. Of course it is possible. Just decide where you want to store old file paths ( config file, registry, etc )

I was running an exe .
Now my question is , Can i programatically check whether the exe has been executed completely.
Does the framework class
System.Diagnosis.process has anything to do with the remedy of this problem?
|
|
|
|
|
well,you could enclose it in a try ..... catch and get the message of the exception and find out,if there is no exception message,then the file would have been executed 'completely'
|
|
|
|
|
is there ant alternative way out ?
once the program enters into the catch block.it takes time to complete the execution.thus increases the access time.
|
|
|
|
|
if you use a generic exception such as "Exception" it will take a lot of time,to reduce that time you have to choose a more specific exception.The more generic your exception,the more longer the processing time.So its a compromise between Accuracy and Speed.
|
|
|
|
|
i actually do not know how to check whether the particular exe has been executed completely.
|
|
|
|
|
What do you mean by "execute completely"?? Are you asking if the child process terminates? Are you looking for an exit code? A file waiting to be written?? What?

Is there a way to determine when i'm in runmode in vb6. I don't want to subclass a window when it is in design mode.

There's a way to determine when the program is running in the VB IDE context.
Are you asking for this?

yes (i think). I have a usercontrol and in there i subclassed one of the constituent controls, but I only want this subclassing if i'm running and not while it is sited on a container in the design mode.
