You could conceivably create a ramdisk, assign it a drive letter, and save your file in there. This effectively creates a temp location for you to write data to that isn't part of the rest of the system, and gets wiped out as soon as you reboot.<br />
<br />
You can't do that directly from VB, though. Rather you have to install the ramdrive.sys driver and setup a ramdisk that way. Then you can access it as a drive letter just like you'd access anything else.<br />
<br />
This is what Microsoft calls a &quot;sample driver&quot;, and, as they say, &quot;Neither the driver nor the sample programs are intended for use in a production environment&quot;. Also I have no idea if this will work on Vista. It only is advertised to work on 2000/XP. <br />

VB6 open excel/word/adobe with Byte Array

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
