Then my previous advice should work. Just use MenuStrip1.Enabled = False and MenuStrip1.Enabled = True.
|
|
|
|
|
but what u suggest
MenuStrip1.Enabled = False
enable and diseable all the menu ,means enables the login menu also//
so how the user will logon

You stated you wanted to disable/enable the main menu. This to me meant the whole menu. To individually set items you can create a loop that iterates through each item and disable/enables it.
'Option #1
With MenuStrip1
'Disable each menu item
For i As Integer = 0 To .Items.Count - 1
.Items(i).Enabled = False
Next
'Enable the one(s) we want by index
.Items(0).Enabled = True
End With
'Option #2
'Disable each menu item
For Each item As ToolStripItem In MenuStrip1.Items
item.Enabled = False
Next
'Enable by using it's name
MenuStrip1.Items("FileToolStripMenuItem").Enabled = True
Enabling the items would just be a simple change

dear friends
when create a sql connection this code is automatically generated
Me.OleDbConnection1.ConnectionString="Provider=SQLOLEDB.1;Password=xyz;Persist Security Info=True;User ID=sa;Initial Catalog=try;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Use Encryption for Data=False;Tag with column collation when possible=False"

Try searching on "optimistic locking" and "concurrency". .NET provides a bunch of support for this.

Hello all,
I have heard rumors that there is logic or an algorithm that will analyze a live video stream through software and will give a numeric value for the focus. I am looking for a way to calibrate/focus CCTV cameras through a custom piece of software. If this type of algorithm exists, it would allow me to get the tighest focus possible (by using the software and numeric value) rather than trusting what looks good to my eyes.
If you know of something or find something, let me know also if it work with either BNC video out or with the IP based cameras. Most of the cameras I use are IP based (which also happen to be motion jpeg or mjpeg instead of true video stream) so I am sure that will affect things.
All I have found is people talking about this for thier telescopes/astronomy.
Thanks for your help!!!
Mike

If this is using COM, Microsoft do have a .NET framework for working with Office in .NET.

Start with what I said. There's a .NET Office library from MS, you can try to use that.

I have a rich text box and I would like to replace a line of text e.g. "4443334" with ("SSS"+ RTB.text + "people") how would you do that?
Also, I have a button save called "SaveRTF" how would you get it to save the contents of the Rich text box "WebRTF" as a HTML file?
In the end we're all just the same

I am writing a website and find it hard putting in similar information for pages that will be similar all the time. I have created a program HTM Generator that I want to to this for me.
Many of the pages I put in are similar, except for some details. What i want to know (Using VB.net 2005) How I could load up file "LepTem.htm" when program loads and use text box "txtheading" with text say "Welcome to our site" to generate a heading tag or replace current one with <tag>"text from text box". If tag exists i want the program to overwrite it. The when you click save, I want it to bring up a save as screen and save only as a HTML file.
How would I do this? I hate having to write the same things over again cause I only have to modify a few things.
Also, I have another text box called "txtxscientific" and on the second column to the right on the table, I want it to put text there. And I have another text box I want text on third right. How would you do this?
In the end we're all just the same

Create a base page class which holds all this information. If it's visual, use master pages, if you are using 2005.

Had a far better idea. Same principals, but instead I have three tab pages. Pages one and two have text boxes for inputting information. How would I get say "txtscientific" when iformation is typed in, automatically replace a certian tag on a certian line in the rich text box "RTFHTML"? This way seems easier.
I have put the whole HTML info on the rich text box and set the box to read only. The I want to whenever I type in text boxes in tab pages 1 and 2, the info to automatically change. How would you do that instead?
In the end we're all just the same

Hi,
I want to make a web application in vb.net connected to access database. How do I do that?
I noticed that when oracle is used, the following code is neccessary:
imports oracle.dataaccess.client
imports oracle.dataaccess.types
How about access db?
==========================
Be positive, it helps...

Access uses the standard Sql namespaces, SQL Server and Oracle get their own, specialised versions.
If you google, you'll find tons of info on this.

hello,
How can I filter last 30, 60, 90 and last year's records in my dataGridView?
I would like to do it in VB.NET

Have you stored the date in your database ? If so, your SQL can filter it. If not, I doubt you can.

Hi,
Yes. dates are in the dataset in the table. I am looking for the SQl statement to do that.

GetDate() will return todays date, use that in your SQL statement. DateAdd is the other function you need to get a date that's a certain distance from today, I believe.

i think you can do this
col1 = is a date colum
select col1 from table
where col1 > getdate() - 30

What is the difference in purpose/whatever between just creating a Method or Function and calling it when necessary and creating an Event and then raising an event? I just discovered this but cant think of a whole lot of reasons for me to use it.
