Sharing a module (containing classes) between projects

Matt Philmon3-Sep-03 11:32

3-Sep-03 11:32

I have 2 class libraries and a Windows Application that use a common set of of structures and classes to pass and manipulate data. Each is written in VB.NET. My thinking was to create a public module, shared through Source Safe so a GetLatest would at least update all projects before a build. Now, many of the public and private methods within each class library pass data types that include some of these "shared" structures and classes.

I was planning on simply including that public module in each of these projects so the type information would be common knowledge. However, it doesn't work... the compiler says (for instance in the Windows application) that the type should be ClassLibrary1.modPublicStructures.clsMyClass and not MyWindowsApp.modPublicStructures.clsMyClass.

Now, I KNOW I can simply create yet another class library that contains this set of common classes and then add a reference to that new class library to each of these projects... but that's now ANOTHER DLL added to the project. Surely there's another way to accomplish this.

ActiveX Control

Hi there!

I'm kind of new to VB, but not really new to windows-programming.... Unsure | :~

Here's my prop:

I have an ActiveX Control [MyControl] which I have to do, but this control has to use another (special) ActiveX-control [specControl] within, so I have to pull the properties of [specControl] through [MyControl] that I can use them together in other applications. (OK, sounds wiered, but is'nt really)

So, what do I have to do that I can use the properties of the special control???

Thanks in advance!!

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.

Help with WM_GETTEXT

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).

This is my first foray into the world of Win32 APIs and VB.Net so your help would be much appreciated.

Clean Build

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.

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.

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.

Hello all..
How to get the icon that is associate with the file?

I have email item... which contain file attachments..
So first get the file attachment using mail.Attachments and mail.Attachment. Up to here no problem..

here the code to get the icon and saving it in C:\PCKM so I can call the image file from HTML code

<br />
Function GetIconLocation(ByVal filename As String) As String<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 />
        Dim hImgSmall As IntPtr  'The handle to the system image list.<br />
<br />
        hImgSmall = SHGetFileInfo(filename, 0, shinfo, Marshal.SizeOf(shinfo), SHGFI_ICON Or SHGFI_SMALLICON)<br />
        Dim hIcon As Icon<br />
        hIcon = Icon.FromHandle(shinfo.hIcon)<br />
<br />
        Dim bip As System.Drawing.Bitmap<br />
        bip = hIcon.ToBitmap()<br />
        bip.Save("c:\pckm\icon.bmp")<br />
        loc = "<img src=""c:\pckm\icon.bmp""><br>" & filename<br />
<br />
        GetIconLocation = loc<br />
    End Function<br />

After I saved the icon.bmp I try to open it by double clicking the file or using open with to oen the file but can't open with any other programs

How to save the icon to the hard drive???

Thank you

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

for example:

 str = "<img src=""c:\this\is\icon\location\attachmentIcon.ico""><br>"_<br />
& aAttachment.Name

here is my code to get the icon location... This code doesn't work as I want ( I want to get the directory of the image of icon or attachment icon and put it in the 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 />
