What Would Cause A Dynamic Link Library To No Longer Be Found By VB Program

Apr 17, 2010

My program used to run on my system just fine until I removed some other applications. Then the proggy was giving me a runtime error. The funny thing is that once I installed visual basic 6 and added a reference to dao360.dll, or the Microsoft DAO 3.6 that the program then worked without error.

VB6 was never installed on this system before. The program worked just fine until applications were uninstalled from the system. What happened that caused the reference to stop working? Why did the program stop finding dao360.dll even though the program itself wasn't modified since vb6 wasn't installed?

Object Library Invalid Or Contains References To Object Definitions That Could Not Be Found

May 24, 2009

I get an error while trying to install a third party Excel add-in [Thomson One Analytics]. Error: "Compile error in hidden module: Main" Microsoft Excel 2003..But when I had the Addin unlocked.I noticed that it was getting stuck at a specific line in the MAIN module of the Addin package and the debugger throws a compile error message saying that: "Object library Invalid or contains references to object definitions that could not be found". Earlier when I had this issue,I made another user login to the PC and we were able to use the add-in successfully. But this time even a different user with Admin Rights was not able to use it. [code]

Tried to install and run the Addin on the same computer by a different user having admin rights, no go.Made sure that he references for the add-in in the VBA editor are correct, by comparing them with a working computer, no go Re-installed "Service Pack 6 for Visual Basic 6.0: Run-Time Redistribution Pack (vbrun60sp6.exe)", no go. Ran repairs on Excel, no go Re-installed Excel, no go

How To Do OpenGL Within A VB .NET Environment

Feb 17, 2012

I was trying to learn how to do openGL within a VB .NET environment and it seems that the Tao framework or OpenTK is recommended with OpenTK having a higher recommendation so that is what I chose to try using. Since I am brand new to this, I am trying to just draw a simple box, triangle, or anything really so that I can understand it all before making more complex things. I have been unsuccessful at this so far so I will list in order what I have done so far and hopefully someone here can help me correct it or provide a new example just so I can draw a simple shape.

1) I installed OpenTK using opentk-2010-10-06.exe

2) In a new project I added the references to OpenTK.dll and OpenTK.Compatibility.dll

3) I added the control (opentk.glcontrol.dll)

4) I added the actual control to my form.Using some examples online I added the rest:

5) I wrote my references in:

Imports OpenTK
Imports OpenTK.GLControl
Imports OpenTK.Platform


The above results in no display?

Drawing A Line In VB With OpenGL

Nov 6, 2010

I was wondering if anyone could steer me to any good references to using OpenGL in vb.Net? I wanted to try a simple line drawing test to start off with, and came across many old discussions about using CsGl or the Tao Framework. But I could not get CsGL to import into Net2008 (the Add Reference window simply could not see the DLL that was clearly there when using Windows Explorer). And although I could get Tao to import OK, and found portions of one person's project, I figured that somehow the GL window he was referring to had to first be set up as a GL object (new class?).In addition, all the OpenGL books I have looked at only discuss OGL with respect to some version of C.From what I have gathered, you need a connector between vb.Net and the opengl32.dll libraries and that is what CsGL and Tao are about. But the edumucation resources seem very few.

Installing DirectX Or OpenGL On VB?

Sep 13, 2011

I wanted to install visual Basic or C++ (but Basic really seems easyer to use) with DirectX or OpenGL but I can't get it to work!I've tried Visual Basic Express 2008 and 2010 and i'm getting the same type of errors...

-> Directx

When I try this program [URL]with VB I either get

with 2008 : just a red cross on a blank screen

with 2010 : an unlimited waiting time, and when i click i get an error message that tells me to continue waiting, im forced to CTRL -ALT - DEL to shut down VB.

-> OpenGL:So i've tried a lot of times! they tell me that it's already installed on windows so i don't need any installation but then VB gives me alot of errors, telling me that some part of code isnt recognized!!

i've tried tutorials with Csgl or Tao, but none seem to work...I already got some knowlege of OpenGL but not DirectX, so could anyone please tell me which one does work on my computer and is best for creating a graphics window inside an API that i create, for instance a mob maker?

OpenGL Save Render For Later Use?

Oct 9, 2010

I render a complex shape in OpenGL which requires a lot of calculations, is there anyway to export that to a state like a model that can be opened again later given you wont edit it again?

I can't create them outside the program (with something like Blender) since the shape is computed when the program starts. The render then gets translated, rotated, drawn over, etc. Note, that I don't need to edit the shape though, but I do want it in a 3D state so saving an image isn't an option.

Windows - Displaying Textures In OpenGL In XP Vs 7

Nov 12, 2010

I am running into the strangest problem that I just can't place my finger on. I've been developing an application in for the last couple months in Windows 7. The program involves some basic OpenGL drawing and animation with basic shapes (squares and circles) and basic textures mapped onto pointlists. The time has come to distribute the program to another machine. On some machines though, I encounter problems when I'm drawing textures. I know that openGL is still functional because drawing basic squares and circles still occur, the textured objects are the only things missing.

Error C2661 And C2227 [openGL In VB2008]

Jun 22, 2010

i have to do a college project on this platform so i decided to learn open GL. while working with glui i am facing some problems. i downloaded glui-2.36. I thought of starting with the example1 (code added at bottom of the post) that was included in source folder of glui-2.36. i am using 2008 When i build the project it gives me 3 errors:

error C2661: 'GLUI_Checkbox::GLUI_Checkbox' : no overloaded function takes 3 arguments
error C2661: 'GLUI_Spinner::GLUI_Spinner' : no overloaded function takes 3 arguments
error C2227: left of '->set_int_limits' must point to class/struct/union/generic type

Here is cpp code:

#include <string.h>
#include <GL/glui.h>
/** These are the live variables passed into GLUI ***/
int wireframe = 0;

OpenGL - Animation Stuttering When In Full Screen?

Oct 19, 2010

I'm currently running into a problem regarding animation in OpenGL. I have between 200 and 10000 gears on the screen at a time all rotating. When the window is not in maximized view, my CPU runs at about 10-20 % consistently. No spikes, no stuttering in the animation, it runs perfectly smooth regardless of the number of gears on screen. When I maximize the window though, everything falls apart. My CPU maxes out, I begin getting weird spikes in CPU usage, the animation begins stuttering as a result, and it just looks really ugly, even when I have only 200 gears on screen.

My animation technique looks like this:

While Animating
Calculate current rotation angle based on a running timer
draw Image
call glFlush()
End While

I'm using the Tao framework in I'm not performing any other calculations other than the ones to calculate the rotation angle mentioned above and perform a few glRotateD and glscaleD in the method to draw the image.

In addition, I guess I was under the impression that regardless of the window size in an orthographic 2-dimensional drawing that is scaling on resizing of the window, the drawing time would always take the same amount of time. Is this a correct assumption?

Note that I've seen the animation run perfectly smooth at full screen before. Every once in awhile, OpenGL will decide it's happy and run perfectly at full screen using between 10-20% of the CPU (same as when not maximized). I haven't pinpointed what causes this though, because it will run one time perfectly, then without changing anything, I will run it again and encounter the choppiness. I simply want to pinpoint what causes the animation to slow down and eliminate it.

I've run a dot trace on my program and it says that the swapBuffers method is using 55 % of my processing time even though I'm never explicitly calling the method. Is the method called by something else that I can eliminate, or is this simply OpenGL's "dead time" method to limit the animation to 60 fps?

Rendering Graphics Efficiently - DirectX - Graphics Card And Use Of DirectDraw Or OpenGL

Sep 23, 2011

We have a GIS application that has some performance issues. It creates and sends an image to a web browser.  We start with a Bing Maps imager, add complex polygons (complete with transparent fill), save the finished image as a PNG, and send it to the browser.

The idea has come up that we could possibly install a graphics card and use DirectX or OpenGL to improve performance. I believe this would be the case even though we ultimately generate an image instead of sending the data the the screen. I believe our processes could still make use of the API and the hardware acceleration it provides. Our process is not unlike what CGI film makers do to render individuals frames of a film, though we simply render a single image and send it, as opposed to the hundreds of thousands of images needed for a single CGI film.

So my question is: would a powerful graphics card and use of DirectDraw or OpenGL provide us a worthwhile performance boost?  It can take us 20-30 seconds to render a more complex map. Which is a long time to wait on a web page...

IDE :: Key Not Found Parameter Name:key?

May 27, 2009

I have an issue with the VB IDE My project was working fine.I was adding some combo boxes and adding some code for the combo boxes to the form "iNet_MDI". I ran it in debug a few times to watch it and the next thing I know, I see "Key not Found Parameter name:key" in the Warning list. It says the Warning is on line 369 in iNet_MDI.Designer.vb.When I click on this message, it takes me to line 369 which is "Me.gb_RTO.Font = NewSystem.Drawing.Font("Arial", 10.0!, System.Drawing.FontStyle.Regular,System.Drawing.GraphicsUnit.Point, CType(0, Byte)I can comment this line out and the warning still exists and it still points to the same line.

I have tried to rebuild the project and clean the project.I have tried commenting out alot of the code, but nothing seems to clear this warning message. I can't get to the Design screen to try to remove any tools from the form.  An error screen appears in place of the Designer   I t gives me the option to "ignore and continue", which does not work.I see the Call Stack here on this page and it says:
