I have a simple question for you I think, but for me it bugs me a lot
So as the title says, I want to load a dll from a folder in my exe and use it's classes
How can I do that? like for example my app is named "run.exe" and I want at load time to load dlls from folder "resources" and use the classes from the dll's it "imported"
I wrote a program in VB.NET which uses several .dlls that I programed in c++. The dlls wrap some functions from an old version of the program. On my development computer everything works fine but I build a release version, copy it and the dlls onto the target machine and the .exe starts up fine. When the program tries to use a function from the .dll it throws an exception and says "unable to load DLL "c:/the path/my.dll" the specified module can't be found."I don't know if it makes any difference, but I am defining the dll functions in the main vb project using:Declare Function MyFunction Lib "c:/the path/my.dll" (ByVal in1 as Double, ByRef out1 as Double) as Integer.I have checked the .net framework on the target and version 4 seems to be installed same as the development computer. Both are windows XP machines. I have no idea if it is the way I programmed the .dlls or just something with my vb.net project.
View 1 RepliesWhen I reference a DLL in my VB.net 2005 project, is there any way to prevent it from being copied to the projects release folder? I would just like it to use the dll were it is registered on the server.

Not sure if this is the correct place for this postWhat I am trying to do is update dll's in my application.Using VB with dotnet 2 (Visual Studio 2010)The Project has a number of Dll's one of each department i.e. Sales is sales.dll... Development is development.dll etc....Each dll has classes/User controls which is used and dispose depending on the section within the application.Once work has been completed with a dll, it put in the deployment area, currently another is program launching checks the file verison and updates as required, before the main application lauches, this works. The exe hasn't needed updated for a long time as all the changes are in the dlls.
What i have been looking at is update method for the dll's dymanically, when not in use, when the dll called into use or disposed of.I have looking at LoadLibrary/FreeLibrary and application.domain. I have been reading loads and tried out some of the examples, with a modified to suit. I am just not getting it.
I am trying to understand how to interact with external DLLs written in C++ for use in my VB.NET application. I have some DLLs that a client wrote that do some math functions. Everything was working on a 32-bit machine. Because we were taxing the 32-bit machine we moved to 64-bit. Now we can't get the same functions to work. The DLLs were re-compiled as 64-bit DLLs and they still don't work. So my client wrote some dummy DLLs to see if we could figure out the problem. Here are the "signatures" of the DLL calls that I am making:[code]....Ultimately I would like to get to calling initialize_quiet and I am guessing at the format of the marshalling, const size etc.
View 3 RepliesQuestion: I use an embedded Firebird database in ASP.NET.
Now, Firebird has a .NET wrapper around native dlls.
The problem is, with the ASP.NET compilation and execution process, the dlls get shadow copied to a temporary folder. Unfortunately, only the .NET dlls, and not the native dll.
See [URL] for details.
Now, this makes it necessary to put the unmanaged dll somewhere into the system32 directory (or any other directory in the path environment variable).
Now, I want to change the wrapper/native dll (opensource), so it loads the dlls also if they are only in the bin folder.
Now, my problem is, how can I, in .NET, load an unmanaged dll from an absolute path ? The absolute path is determined at runtime, not at compile-time...
how do I load a .x model from a folder and then show it in a box(a picturebox?) on a form?

I'm trying to make a custom skin maker for a program I'm working for. The concept is, you provide all the images needed for the program in a folder and then load that folder into the program which then sorts out each image in their respective areas. I know how to load files, but instead of making the user load the files one by one I'd like them to be able to load them from a folder.On a related note, I'd also like to know if it was possible to allow my users to move their controls around the program. For example, say they'd like their exit button in a different location as it'd look nicer with their skin, is there a way to allow them to move it? Particularly, it'd be nice to have a check box that enabled or disabled the ability to drag them around so they don't accidentally drag it when trying to click it.Also, how could I save their changes to this skin so it'd load up the same every time without overriding the default skin.
Finally, I have a piece of code that allows me to drag the form around as it has no normal border but I have a button that keeps it on top at all times, I'd like that button to also disable the ability to move the program while active and restore the mobility once clicked again. Here is the code used to move the program if that helps any.

View 3 RepliesI have a small databse program that retrives data from a csv file and he user can select different records based on a combobox selection. Now i want to be abeto display a picture for the record selected that is stored in the same folder as the csv file
Example: c:mydocumentsmydatafolderdatafile1
My program makes a connection to Datafile1 and within each record is a number example: 1234, 5678 etc.... Pictures are in the mydatafolder and have same name as the data record number
So record 1234 will have a picture called 1234
so i need my picturebox to get its image from the folder and match the file name based on the selected record If I am on the right track something like this PictureBox1.Image = Image.FromFile("C:WINNTSanta Fe Stucco.bmp")
However I need the file folder location to be based on what folder user selcted and the file name to be the name (number that is in record of database)
So if user is getting data from c:myfolderdatafolderdatafile3 and has selected record number 1234
The picturebox will get it image from the C:myfolderdatafolder and the file name will be the record number selected in this case 1234
this is the code i have on form load: textbox1.text ="C:Documents and SettingsOwnerDesktop"
here's the code to load the listbox:
ListBox1.Items.Clear()
Dim filepath As String = (textbox1.text)
My.Application.DoEvents()
Try
For Each file As String In My.Computer.FileSystem.GetFiles _
[Code]...
now what this does is load the files w/out the file path or extensions , but, it loads the files in the subfolders as well . i just need the desktop files to load in the listbox, not the subfolder files
I want a list of folder names, i want a list of the names so i can remeber what projects i have on the go.
so example,lets say i have 3 folders in my on my desktop and the names are A, B and C i want get a list of theose names so i remeber what projects i have created.
If you don't understand ill try to re word it more specific

I am working on vb.net win form. My task is display the file names from a folder onto gridview control. when user clicks process button in my UI, all the file names present in gridview, the corresponding file has to be loaded onto memory stream buffer one after another and append the titles to the content of the file and save it in hard drive with _ed as a suffix to the file name.I am very basic programmer.

View 16 RepliesI've seen quite a few questions about calling 32 bit ActiveX components on 64 bit platforms - as I understand it you can't create a 32 bit ActiveX component from a .NET application running in X64 (native) mode. This is OK and I think I understand it.But my question is more basic. Is there such a thing as a 64 bit ActiveX component? or is ActiveX always 32 bit, period?

straightforward method of creating a DLL with properties and methods exposed to other programs? I followed the instructions that I found on the MSDN websites as well as suggestions from forum participants. The DLL should be available both for COM and .NET programs. So far, nothing has worked.There are numerous variations listed on the MSDN site. No doubt there are reasons for the differing instructions. However, I have not had sufficient success with any of them. Sometimes, just building the project makes the class visible to COM compatible programs. Other times, only after running regasm. Still other times, I have to run regasm, sn and gacutil before the DLLs class gets exposed. Then forums posters tell me: "you shouldn't have to do all that.

You developing a application named "DemoSoft" which is going to be a shareware or Premium, you use different DLL's in this project and some DLL's are owned by you, they are very useful and valuable, you are selling this software and are charging the customer for what the software does but since this software uses one of your Valuable DLL, actually few functions from it you have to deploy it and cannot additionally charge for the whole dll. since that would be unwize.now i want to ask what can you do so that This DLL in "DemoSoft" cannot be exploited, meaning end user could use my software but if some thief tries to use my supplied DLL in one of his own app he is unable to do it, in simple terms DLL should work only and only with DemoSoft.

I have a project that references two DLL files in the system 32 directory as COM references. The files are certenroll.dll and certcli.dll which are included in the system32 directory as part of the OS. My app is a console application that I'd like to have as a standalone exe. It seems that the these files are converted to something like Interop.CERTENROLLLib.dll and Interop.CERTCLIENTLib.dll and dropped in the bin directory for my project. Since I want the app to be a standalone exe able to run on other PC's I'd rather see the app reference the original DLL files in the system32 directory and not have to carry these dependency files around with it.
