<P>To install Visual C++ 6.0 on Windows 95, you must be running a protected-mode CD-ROM driver. You can verify this by checking the Device Manager. If you are currently using a real-mode CD-ROM driver, contact your CD-ROM drive manufacturer for an updated driver for Windows 95 before installing Visual C++ 6.0.</P>

<P>You can use the Knowledge Base articles in the MSDN documentation to resolve known installation and operating problems. Select the <B>Search</B> command from the <B>Help</B> menu and search for error message or related keywords to find a problem description and resolution.</P>
<P>Knowledge Base articles, written by Microsoft Technical Support Engineers, are also available by connecting to <A HREF = "http://www.microsoft.com/support/">http://www.microsoft.com/support/</A>, then click "support online." You will have to register the first time. After you have registered, enter your email name and password. Choose "Visual C++" in the <B>Choose a product</B> drop-down list.

<P>The character codes displayed in the "ANSI Character Code Chart" topic will only display correctly if viewed on English systems using an "ANSI-compatible" code page. </A></P>
<H4><A NAME="Setup_7">Resource Viewer and Compiler Not Installed in Some Custom Setup Configurations</A></H4> <!--45394-->
<P>If you install Visual C++ using a custom setup, and omit the Visual C++ resource viewer and compiler, you will not be able to view the project resources.</P>
<P>The workaround is to install Visual C++ with all options (including run-time libraries, MFC and templates, build tools, etc.).</P>
<H4><A NAME="Setup_8">Avoiding Problems Associated with Installing New SDKs</A></H4> <!--46809-->
<P>When installing Microsoft SDKs, compare the header and library dates in the SDK files with the files that were shipped with Visual C++. If the SDK files are newer, you should place the SDK directories before the default Visual C++ INCLUDE and LIB directories listed in the Directories tab of the Options dialog in the Tools menu.</P>

<H3><A NAME="Build_0"></A>Build Issues</H3>
<H4><A NAME="Build_5"></A>Help File Names with European Characters Do Not Copy Correctly on Windows 95</H4>
<P>The Help compiler converts the name of the Help file into uppercase characters. On Windows 95, this causes problems when the Visual Studio Build System tries to copy a name that contains European characters (such as umlauted characters) to the output directory for the rest of the project build. This is not a problem on Windows NT.
</P>
<H5>Workaround</H5>
<P>Add a copy step with the name of the Help file, in uppercase, to the custom build rule on the .hpj file in the project.
</P>
<H4><A NAME="Build_6"></A>"Update All Dependencies" Menu Item Removed</H4>
<P>The <B>Update All Dependencies</B> item has been removed from the <B>Build</B> menu because dependencies are automatically updated in each build. Dependencies are updated at the beginning of the initial build and at the end of every build.</P>

<H4><A NAME="Doc_1.1"></A>New Help Viewer</H4> <!--47137-->
<P>Online documentation is now accessed with a Help viewer based on HTML Help. The Help Viewer can either be installed during the Visual Studio installation or from the MSDN CD-ROM. See the <A HREF="ReadmeDN.htm">Microsoft Developer Network Library Readme</A> for full details on MSDN installation.</P>
<P>Access the Help Viewer by selecting items on the <B>Help</B> menu in the Visual C++ environment. When you bring up Help, you will get a separate window that displays navigation buttons, tabs with contents, index and search, and a pane with text. It is displayed in a similar manner to WinHelp in the Office products. This is the behavior for all Developer Tools products in Visual Studio 6.0.</P>
<H4><A NAME="Doc_1.2"></A>Sample Code Sometimes Does Not Cut and Paste Properly</H4> <!--47119-->

<li><B>TBBS_NOPREFIX</B> - The button text will not have an accelerator prefix associated with it.</li>
<li><B>TBBS_DROPDOWN</B> - Creates a drop-down list button. Drop-down buttons send the <B>TBN_DROPDOWN</B> notification. If the toolbar has the <B>TBSTYLE_EX_DRAWDDARROWS</B> extended style, drop-down buttons will have a drop-down arrow displayed next to them.</li>
