Visual Basic, VB5 Error 50003

VB5 Error 50003 - Unknown Error

Author	Message
Jim McFadde #1 / 4	VB5 Error 50003 - Unknown Error I have a VB5 project with MDI forms. I am developing on NT 4.0W SP3. I had the project running on Win95 and NT4.0 workstations. I spent several weeks making modifications. I completed and it works fine only on my workstation. When the other workstations loaded the new application, they click on a toolbar button to open a customer profile form, it gives the message 50003 - Unknown Error. I have attempted some tracing, and it occurs after the Load command in the main form, but before the load event in the sub form. Does anyone have a suggestion about where to proceed? Thanks.

Russ Evan #2 / 4	VB5 Error 50003 - Unknown Error This is a known bug in VB5. SYMPTOMS Loading a GIF file that does not specifically contain an Image Object into Visual Basic 5.0 (for example, through the PictureBox control), generates the run-time error 50003: "Unexpected Error" CAUSE Visual Basic 5.0 does not support GIFs that include images that are contained within Application Blocks. The Image Object must be included in the GIF as a separate Image Object. RESOLUTION Use one of the following methods to work around this problem: Use Error Handling to trap for and handle appropriately error 50003 (unexpected error) in your Visual Basic application. For more information, search for the Help topic "Designing an Error Handler" in the Microsoft Visual Basic 6.0 Online Documentation. Ensure that images contained within a GIF file are included specifically as Image Objects and not contained within Application Blocks. What all this basically means is don't load a picture with the loadpicture method; instead, assign the graphic at design time. Quote: >I have a VB5 project with MDI forms.

Jim Deutc #3 / 4	VB5 Error 50003 - Unknown Error The 50003 error is a real pip, ain't it? It has several possible causes. The only documented one I know about has something to do with gif files. More often, it's caused by having mismatched/out-of-date system files. The OLE*.DLL files are the first suspects. Check the versions on the bad machines vs. the good ones. Try downloading OADIST.EXE from the MS website: it doesn't install the _latest_ versions, but at least it's a matched set! Also watch out for Comcat.dll version 5.0. This seems to break many systems. Going back to v4.71 generally seems to make things OK again. VB5 ships with DAO350.DLL version 3.50.3602.0 which is used for some database access. If you install VB6 or Visual Interdev 6 on your machine, you will be upgraded to version 3.51.1608.0. This version requires EXPSRV.DLL which the earlier version does not. If you use the VB5 application wizard it will distribute the 3.51 version but NOT the EXPSRV.DLL file. When installed on another machine without VB6 or VI6, the DAO350.DLL is overwritten with version 3.51 but they do not get the EXPSRV.DLL. Now they may get error 50003 for this application and the same or other errors for many existing applications using DAO350.DLL. Good luck: this one can be tough!

Jim McFadde #4 / 4	VB5 Error 50003 - Unknown Error Thanks for the responses. It appears in this case that the use of the load picture was doing it. When I put them in at design time, the problem went away. Thanks again Quote: > I have a VB5 project with MDI forms. I am developing on NT 4.0W SP3.
