Hi,<br />
MSSTDFMT.dll is for Microsoft Standard Data Formatting. Have you included it in your package/CD? Not sure whether it is present in system32, as it's part of Visual Studio.<br />
Try to include it in your package and then load.<br />
Cheers,<br />

<div>
The dll is on the cd. However I don't want to create a package that the user has to install.<br />
I just want the user to run the .exe off the cd
</div>


<div>
Ok.<br />
Try to check, whether the load liabrary successfully loads the dll. You can check this by the returned value of LoadLibrary function, if it is zero then there might be some problem while registering the dll. You can retrive the last dll error to check exact error code.<br />

<br />
One quick question, have you used any databinding?<br />
If yes, then check the DataFormat property in design time of controls like textboxes, comboboxes, checkbox, listbox etc. used in your application. If it's not blank then make it blank by deleting the control and adding new from toolbox. To format the data, assign the format at runtime after data binding.<br />
If No,then blank the DataFormat property for controls as mentioned above, skip loading of msstdfmt.dll, and remove reference of &quot;Microsoft Data Formatting Obejct Library&quot; from reference if any. <br />
I think, this should solve your problem<br />

<div>
I didn't use any data format. I tried making a small app to register MSSTDFMT.DLL and then tried running my app and it works.<br />
<br />
From what I understand my program is using a function in that dll before I register it.<br />
the only thing that it's being done before registering the dll is getting the cdrom drive letter, so maybe I have a function that uses that dll.<br />
I'll go check right now

<div>
Ok I found the problem. I can't seem to register MSSTDFMT.DLL using loadlibrary. While all the others dll are loaded, this one doesn't
</div>


<div>
thanks man,<br />
the problem was actually that I had the dataformat property set to a textbox. Deleted it and now it works

Hello,<br />
I'm developing a software that will run off the cd-rom, but without installation.<br />
I'm currently registering all the dll's and ocx's on the fly, if they are not yet registered in system32.<br />
The problem I have is with MSSTDFMT.DLL.<br />
<br />
When I start my app, I get &quot;Class not registered. You need to install the file MSSTDFMT.DLL&quot;<br />
<br />
I'm registering the dll on the first line of the FORM_LOAD event, using the function LoadLibrary(dll) defined as:<br />
<br />
Private Declare Function LoadLibrary Lib &quot;kernel32&quot; Alias &quot;LoadLibraryA&quot; ( _<br />
ByVal lpLibFileName As String) As Long<br />
<br />
Any ideas on how to overcome this problem? I don't want to make any installation, I just need to run the app when the cd is inserted. Also I didn't want to use regsvr32 because I'm not able to know if I have administrator rights in every computer I will use the program in

Registering MSSTDFMT.DLL before program starts

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.
