You have 2 options:
1. Add a property Get "specControl" (or whatever name you want) to your MyControl with return type specControl. This makes the all properties/methods of specControl accessible for the outside world. A thing to be aware of is that you test/handle _every_ possible combination of specControl and MyControl, because you don't have control over specControl anymore.
2. This is usually a better solutions although looks like/is duplicating code. Add properties of specControl to MyControl which you want to make available to the outside world. In the implementation of those properties you're internally forwarding to specControl. With this option _you_ are in control of specControl.
Hope this helps.

I am using the SendMessage API to read text from a textbox in a third party application.
I am calling it using the following command:
Win32API.SendMessage(hwnd, WM_GETTEXT, textlength, mymessage)
where hwnd is an Int32 representing the textbox handle;
WM_GETTEXT is a constant
textlength is the number of characters to be retrieved; and
mymessage is the string to store the info.
Everything seems OK apart from the fact that when I try and display the string it simply appears as a series of blobs.....not readable text (see below).
片敡敭丠睥慭敔瑳倠条eಇ䐁
This is my first foray into the world of Win32 APIs and VB.Net so your help would be much appreciated.

Hi
I have a large project which refers to a number of dll's. These dll's are in small projects which I often go back to and change from Debug to Release and then rebuild them.
The main project is also often switched from Debug to Release.
What I'm now finding is that if I press F5 from the IDE (either in Debug or Release), even though the Output window says its building the project, any changes I've made to the main project are not reflected in this build.
However, if I select from the menu, Build and then press F5 the new build is fine.
I've tried deleting all *.dll;*.exe;*.pdb but this seems to help for a couple of hours, and then it goes back to its old behaviour.
Has anyone else experienced this ?
TIA
Jeremy

Does the same problem occur if you Build >> Rebuild Solution instead of just using F5?
This seemed to solve our issue.
Cheers,
Simon

Yes it still happens with Rebuild Solution - note its one of these intermittent problems, sometimes happens sometimes doesn't. I've just got into the habit of doing a build before a run - but its still very irritating.

How can i change the font, forecolor,caption and ...

The easiest way(maybe the only one) is to make your own MsgBox !!
Create a with label to hold the text and put buttons (OK,Cancel,etc..) and make them visible/invisible according to parameters passed.
|
|
|
|
|
The short answer is you can't! The long answer is to write your own MsgBox function.

mailItem.attachments.attachment
So far no problem.. I got the attachment file name. still no error..
Here the problem come..
how to get the attachment icon?? I used the following code (SHGetFileInfo) to get the file attachment icon location
so I can print the file attachment name with its associate icon on the paper ( same as printing from the printer) using HTML Code

<br />
Dim loc As String<br />
'Use this to get the small icon.<br />
Dim fName As String 'The file name to get the icon from.<br />
Dim shinfo As SHFILEINFO<br />
shinfo = New SHFILEINFO<br />
Dim openFileDialog1 As OpenFileDialog<br />
openFileDialog1 = New OpenFileDialog<br />

How do i write a program that it use randomize to generate 2 postives number and sum them up. There are four choices for user to choose, this four choices are also generate from randomize. Question and answer generated should be between 1 to 100.
|
|
|
|
|
Random r = new Random(DateTime.Now.Second); //initalize the generator
//generate two integers between 1 and 50
int number1 = r.Next(49)+1;
int number2 = r.Next(50);
//sum up the numbers - result cannot be <1 or >100
int sum = number1 + number 2;
//generate more numbers...
What do you need this for, is it homework?
|
|
|
|
|
Sorry, I posted that in C#. Here is VB:
Randomize (Timer)
Dim number1, number2, sum As Integer
number1 = (Rnd() * 49) + 1
number2 = (Rnd() * 49) + 1
sum = number1 + number

 I just started learning the vb.net and I would like to know how can I check if a subkey exists in the registry and use a code to create the subkey it if does not exist in the registry.
All help will be welcome.
Thank you,
Simon

There is an example of this very topic on the samples for VB.NET:
Private Sub DoesKeyExist
Dim regVersion As Microsoft.Win32.RegistryKey
regVersion = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsoft\\TestApp\\1.0", True)
If regVersion Is Nothing Then
regVersion = Microsoft.Win32.Registry.CurrentUser.CreateSubKey("SOFTWARE\\Microsoft\\TestApp\\1.0")
End If
End Sub
This will check to see if a key exists, then if not, creates it.
Oh yeah! It also needs a reference to the Win32 namespace.

I am using VB.net I am looking for a way to export a registry key like
HKLM\System\CCS\Control\Services (the whole key and all subkeys).
I would like to use the same methods that Regedit uses.
BTW: I am connecting to a remote machine's registry.
Question #2.
How do I determin the data type of a registry key. I understand how to read the value name and value but not the data type.
Example.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update
Value: AUState
Data Type: Reg_Dword <----This is what I am looking to discover.
Data: 2

It looks like RegEdit has its own enumerator built in. There is no function in the .NET framework that does the exact samething, so it looks like your going to have to write your own exporter.

The .NET framework doesn't offer a function to do what your want. Your probably going to have to write a C++ component to return that info.

I want to use SendMessage to send a WM_UPDATEUISTATE message that I hope will show the focus rectangle on option buttons but I cannot find the constant values for the expected wParam values: UIS_CLEAR, UIS_INITIALIZE, UIS_SET, UISF_HIDEACCEL, UISF_HIDEFOCUS, UISF_ACTIVE.
I know that I can change a setting in the Control Panel (Display - Appearance - Effects) but I want to be able to control this programmatically.
Any ideas?

If I read this right, you just want to move the input focus to a button control. In VB.NET, that's easy:
controlName.Focus()
will set the focus to that control. BUT!! (There's always one of these!)
Long version:
A control cannot receive focus unless it is enabled, is visible, AND HAS A WINDOW HANDLE ASSIGNED TO IT! What this means is, you can only set the focus to the control AFTER it has actually been created and it's Message Loop is up and running.
Short version:
If you try and set the focus to a control in a Form's Load event, you must first Show() the form, THEN set the focus to the control. Otherwise it won't work.

Thanks for the reply, but no. What I want to do is tell Windows to show a focus rectangle around the text of a button that has input focus. By default in XP it does not. Also, I am using VB6, not .Net.
If you search MSDN for the WM_CHANGEUISTATE Message you'll see exactly what I'm talking about.
On the other hand, if you have .Net and you search your local help file for the UIS_ and UISF_ constants specified in this tread's header, might you be able to tell me the numeric value of these constants?
For example, I know that...
WM_CHANGEUISTATE = 295 (H&0127)
WM_UPDATEUISTATE = 296 (H&0128)
WM_QUERYUISTATE = 297 (H&0129)
...but I do not know the value for these other constants and they are not known by VB6 because it pre-dates their use in the operating system (beginning with Win2000).
