You've got me there. I haven't a clue how to do a dictionary.

I have no idea of the VB sytnax, but a dictionary is an associative container, so you'll end up able to do this
Dim c as Control = myDictionary("MycontrolName")
It's something like
Dim dic as Dictionary(String, Control)
It's a generic container.

Thanks for that.
The dictionary did sort a few things out and run faster.
It would be better if you didn't have to loop through to find what you need.

I don't think you can have it centered on the TableLayoutPanel.

The best way to do this, is randomise it at the source. The other way to do it, is to randomly remove rows from your data. Where does the data come from ? Can you explain using more than four words ?

Hi there,
You can create four registry entries to keep the last edited document's name and path, and each time a new document is created you save it to the top registry entry and move the other documents down the line, and so keep track of the last edited documents. Just a sugestion, hope you can make it work.

Hi there,
Here is a simple sample of what I should use to save the last recent documents of my app. Look at the sequins of moving the most recent files into their positions. Hope you can make something out of this.
SaveSetting("AppName", "RecentDocs", "Recent5", GetSetting("AppName", "RecentDocs", "Recent4"))
SaveSetting("AppName", "RecentDocs", "Recent4", GetSetting("AppName", "RecentDocs", "Recent3"))
SaveSetting("AppName", "RecentDocs", "Recent3", GetSetting("AppName", "RecentDocs", "Recent2"))
SaveSetting("AppName", "RecentDocs", "Recent2", GetSetting("AppName", "RecentDocs", "Recent1"))
SaveSetting("AppName", "RecentDocs", "Recent1", "Your new File Name and Path")
'SaveSetting' saves data to the registry and 'GetSetting' gets data from the registry. These data will be stored under the local user's registry and will not be available if the windows user is changed.

:(I'm using this code to save the settings:
SaveSetting("program", "programSettings", "bgcolor", textbox1.BackColor = ColorDialog1.Color)
I'm using this code to get the settings
dim a$ = getSetting("program", "programSettings", "bgcolor")
then I used this code to assign the settings back:
me.textbox1.BackColor = new color(a)
 obviously it doesn't work! can anyone help me? extremely argent my project is at a halt.

This looks to me like it would save a boolean, the result of checking if textbox1.BackColor is the same value as ColorDialog1.Color.
This is an artefact of VB being crap, sorry. Or, I am wrong, I could be. What happens when you step through the code ? Why do you have an assignment ( or equality check, how do you tell the difference in VB ? ), inside the Save code ?
Surely your variables are not called Text1 and ColorDialog1, REALLY ???

I don't know; I just got the code, it doesn't work.
I will put it simply, can anyone tell me how to save and retrieve a BackColor, so I can assign it back on startup.

Getting code off the web is fine, so long as you're able to understand it. If you can't understand it, then you should stop and work through a book, so you know enough VB.NET that the web helps you with syntax, not with writing code.
To store a color, you'd probably store the red, green and blue components as integers, then you'd use those to create a color again.

Hi there,
The statement 'textbox1.BackColor = ColorDialog1.Color' generates a boolen value, not the value of the color code. Do it as follow:
TextBox1.BackColor = ColorDialog1.Color
' Save to registry
SaveSetting("program", "programSettings", "bgcolor", TextBox1.BackColor.ToArgb)
' Apply from registry
Me.TextBox1.BackColor = Drawing.Color.FromArgb(GetSetting("program", "programSettings", "bgcolor"))

Hi! could anyone tell me how to convert a string(that is a font) that I saved to to reg using savesetting(..) to font object using getsetting(..) so I can assign it back a textbox.
summary: convert string back to font
thanx in advance.
|
|
|
|

Well, what is the value of the string ? Does it specify font name, size, weight, etc ?

Hi there,
The best is to save each setting of the font into its own registry entry, or save the settings of the font in delimited format into one registry entry and reverse it into a new font value that you can apply to the textbox.

Hi,I'm trying to create a database connection...
connstr as string
connstr="DSN=****;uid=***;pwd=***"
.....
what do you suggest to make it more secure since the connection string is stored in the app.config.
I have tried using the rsaprotectedconfigurationprovider like what the msdn recommended...
Imports System
Imports System.Configuration
Public Class UsingRsaProtectedConfigurationProvider
' Protect the connectionStrings section.
Private Shared Sub ProtectConfiguration()
' Get the application configuration file.
Dim config As System.Configuration.Configuration = _
ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None)
' Define the Rsa provider name.
Dim provider As String = _
"RsaProtectedConfigurationProvider"
' Get the section to protect.
Dim connStrings As ConfigurationSection = _
config.ConnectionStrings
If Not (connStrings Is Nothing) Then
If Not connStrings.SectionInformation.IsProtected Then
If Not connStrings.ElementInformation.IsLocked Then
' Protect the section.
connStrings.SectionInformation.ProtectSection(provider)
connStrings.SectionInformation.ForceSave = True
config.Save(ConfigurationSaveMode.Full)
Console.WriteLine( _
"Section {0} is now protected by {1}", _
connStrings.SectionInformation.Name, _
connStrings.SectionInformation.ProtectionProvider.Name)
Else
Console.WriteLine( _
"Can't protect, section {0} is locked", _
connStrings.SectionInformation.Name)
End If
Else
Console.WriteLine( _
"Section {0} is already protected by {1}", _
connStrings.SectionInformation.Name, _
connStrings.SectionInformation.ProtectionProvider.Name)
End If
Else
Console.WriteLine( _
"Can't get the section {0}", _
connStrings.SectionInformation.Name)
End If
End Sub 'ProtectConfiguration
' Unprotect the connectionStrings section.
Private Shared Sub UnProtectConfiguration()
' Get the application configuration file.
Dim config As System.Configuration.Configuration = _
ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None)
' Get the section to unprotect.
Dim connStrings As ConfigurationSection = _
config.ConnectionStrings
If Not (connStrings Is Nothing) Then
If connStrings.SectionInformation.IsProtected Then
If Not connStrings.ElementInformation.IsLocked Then
' Unprotect the section.
connStrings.SectionInformation.UnprotectSection()
connStrings.SectionInformation.ForceSave = True
config.Save(ConfigurationSaveMode.Full)
Console.WriteLine( _
"Section {0} is now unprotected.", _
connStrings.SectionInformation.Name)
Else
Console.WriteLine( _
"Can't unprotect, section {0} is locked", _
connStrings.SectionInformation.Name)
End If
Else
Console.WriteLine( _
"Section {0} is already unprotected.", _
connStrings.SectionInformation.Name)
End If
Else
Console.WriteLine( _
"Can't get the section {0}", _
connStrings.SectionInformation.Name)
End If
End Sub 'UnProtectConfiguration
Public Shared Sub Main(ByVal args() As String)
Dim selection As String = String.Empty
If args.Length = 0 Then
Console.WriteLine( _
"Select protect or unprotect")
Return
End If
selection = args(0).ToLower()
Select Case selection
Case "protect"
ProtectConfiguration()
Case "unprotect"
UnProtectConfiguration()
Case Else
Console.WriteLine( _
"Unknown selection")
End Select
Console.Read()
End Sub 'Main
End Class 'UsingRsaProtectedConfigurationProvider
but I can't find system.configuration.configuration and configurationmanager.
Also, i tried searching in the object browser the configurationmanager, and it says that its part of system.configuration, but still can't find it...

1. Add the connection string to the web.config section
<configuration>
<connectionStrings>
<add name="DBConnectionString" connectionString="whatever" />
</connectionStrings>
...
/configuration>
2. Add a <machineKey> element to your web.config:
<configuration>
...
<system.web>
<machineKey validationKey="AutoGenerate,IsolateApps"
decryptionKey="AutoGenerate,IsolateApps" />
</system.web>
</configuration>
3. Run aspnet_regiis.exe tool to encrypt the <connectionStrings> element:
aspnet_regiis -pe "connectionStrings" -app "[Your App Name]"
4. Run the aspnet_regiis.exe tool to encrypt the <machineKey> element:
apnet_regiis -pe "system.web/machineKey" -app "[Your App Name]"
5. Run the aspnet_regiis.exe tool to grant access to the key container by the ASP.NET identity:
apsnet-regiis -pa "NetFrameworkConfigurationKey" "[ASP.NET User]"
