He says, he's a newbie. To me, that means he want to open a hard coded (I know, bad idea!) path for each button.
Now, if he wanted to write a configuration section for his app, then he can supply the FBDialog to get the folder and make the app a bit more user friendly. But, I didn't see that in the OP.
 I know, it sounds like I'm harpin' on you. I'm really not. If the OP wants to finish reading this thread, then he can see this idea and start asking questions to take his app to the next level.

Hi I am having the function like this,
Public Function GetColorFromString(ByVal strColor As String) As System.Drawing.Color
Dim colConvert As New ColorConverter
Return colConvert.ConvertFromString(strColor)
End Function
I got error while compiling
"Option Strict On disallows implicit conversions from 'System.Object' to 'System.Drawing.Color'."
How to resolve it?
Be simple and Be sample.

Do the cast explicitly ( however you do that in .NET ). CType, I think.

Yes I got it, I have used like this,
Public Function GetColorFromString(ByVal strColor As String) As System.Drawing.Color
Dim colConvert As New ColorConverter
Return CType(colConvert.ConvertFromString(strColor), Color)
End Function
it is working thanks.

Hello, i need to implement a Progress Bar into my application, the progress bar's listed in this forum and the ones that I found on google, did not match with what I was looking for.
My application is a basic and simple app, which is useful at the same time, it will allow the user to select a application from the listbox and download it to their desktop, where you are not required to register, await comfirmation or anything like that when downloading free applications online such as, AVG, Spybot etc. (I am aware AVG, Spybot do not require a sign-up to download them, I just used them as a free application example)
I am in need of help to get a Download Progress Bar which determines the % completetion of the file being downloaded, more like a Download manager.
How would I go about doing this? here is a theory I came up with:
- Specify the file size, the ping and the connection speed for each site that it will download from (Each application will have 2-3 different mirrors).
Kind regards,
Syri

Each of thse applications downloads their code using their down, custom written, download component so that they can get the progress in bytes, not time. You'll have to do the same because the built-in methods in the .NET Framework don't report back any kind of progress.

Hi
you need know the total bytes to download, each byte is calculated as a porcent of total, where total bytes is 100%.
Progressbar Max property = 100
value = (bytes recibed / total bytes to recibed) * 100
To know the total bytes you must add every files sizes, if you are using http headers in response from server under http 1.1 i believe what the server must say the total size of file.

How can i take screen shots of client from server using .net

Bugs can neither be created nor be removed from software by a developer. They can only be converted from one form to another. The total number of bugs in the software always remain constant.

You'll have to have a client application running, obviously on the client machine, that takes the screen shot and sends it to the server. You can't grab a screen shot using only server-side code.

could you provide how you create the (public_connection) ??
When you get mad...THINK twice that the only advice
Tamimi - Code
|
|
|
|
|
Public connect As New OleDbConnection()
connect.ConnectionString="connection String"
this i have created in the module
|
|
|
|
|
did you call the method that call the above code in the module!!
then are you sure that your connection String is valid one ??
When you get mad...THINK twice that the only advice
Tamimi - Code
|
|
|
|

In the module
Public connect As New OleDbConnection<br />
<br />
Public Sub connection_string()<br />
connect.Connectionstring="Provider=SQLOLEDB.1;Password=xyz;User ID=sa;Initial Catalog=inventory;Auto Translate=True;Packet Size=4096;Use Encryption for Data=False;Tag with column collation when possible=False"<br />
End Sub
then on the startup form
Public Sub New()<br />
MyBase.New()<br />
connection_string()<br />
'This call is required by the Windows Form Designer.<br />
InitializeComponent()<br />
<br />
'Add any initialization after the InitializeComponent() call<br />
<br />
End Sub
this way the string is assigned to the connection

Dear,
Its better to create a common connection class with Connection defined
along with Dateset , Adapter,
So that its better managed .
Thuogh i didn't understood your connection and forms layout and requirement
I thing to remenber In .NET that ADO.NET uses Dissconnected Architecture.
Hope to help,Though this may not be exact , but you can getback to me for any help related

TIP: Share the connection STRING, but not the connection object. The connection will be pooled so opening and closing a connection has no performance impact.
When running a query the following is generally regarded as best practice: Aquire connection, perform query, release connection. Keeping the bit between aquiring the connection and releasing it again as short as possible.

Having initially a diseabled main menu,
how can i enable this menu when the user loggon?
and diseable it when the user logout?
other then using
me.item1.enable=true
me.item2.enable=true
is there a way like :
for each item in menu
item.enable=true??
regards?
Regards
Ramy

I assume you've added a MenuStrip to your form? You can disable the whole menu by setting it's enabled property to false and enable it by setting that property to true. You don't need to do on an item by item basis, unless I'm not understanding you correctly.
|
|
|
|
|
yes i have used a menustrip
what i want when theu user Log enable the menu
when he logout ,disbale the menu
Regards
Ramy

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
Regards
Ramy

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
