I'm trying to learn how to call functions in C DLLs from Visual Basic programs. I'm new to VB but have years of experience in C programming & want my functions to be usable by people who are more familiar with VB.
I managed to create a C DLL & call the functions from a C program. One difficulty I had was that I wanted to put my DLLs in a MyExes directory so I could easily have several unrelated programs call them. It was far from obvious how to tell the compiler & linker to look for the DLL in some arbitrary folder but I eventually found out.

Now one of my difficulties with DLLs & Visual Basic is how to tell Visual Basic 2010 Express to look for functions in a DLL in some arbitrary folder. I tried to use Project->Add Reference, then in the Browse tab went to the folder & DLL I wanted to use, but got the message box:"A reference to C:ProgramFilesMyExes....dll could not be added. Please make sure that the file is accesible and that it is a valid assembly or COM component."I've tried to find a walkthrough to take me through the steps of using C DLLs in VB 2010, but so far had no luck.
i have created a batch file and have added it to the project using add items. Basically what i am aiming at is to execute this file on a button click action. I am using System.Diagnostics.Process.Start("hello.bat") command to run this file i have changed the build action to resource for this batch file. But when i run this program, it is not able to locate the batch file. I am required to give a relative path as the path my vary from machine to machine. how can i make this file accessable using a relative path?
I have a web site project where I need to use the System.Security.Cryptography.Xml.SignedXml class. I added the Dll System.Security as a reference and imported the namespace into my project. It compiles successfully but when I debug the project I get a compilation error:
Compiler Error Message: BC30002: Type 'System.Security.Cryptography.Xml.SignedXml' is not defined.
I have two FlowLayoutPanels in a Form. The first read images from a DIR and expose them generating so many PictureBoxes are necessary. The user can drag an image and drop into the second Panel. All works fine. Now the problem is how can I know the name of the image contained in the PictureBox in the dropped Panel so that I can save it? I tried to recover in a ListBox the name of the images during the population of the first Panel but I don�t know witch may be the reference with the dropped PictureBox.
When i upgrading visual basic 6.0 code to VB2008 by the tool of visual studioïTool->upgrade visual basic 6 code, an error arose.The following is the error message: "File I/O error:the given path's format is not support. Delete _vbsnipup directory and try again."
I have added a reference to the System.Data.SqlClient, but i am not able to use its components while coding, But when i import it in the form class i able to use the component.
So,Is importing a namespace and adding a reference two different things?
I was trying to make my program see if facebook.com was running in internet explorer.
I added the following
Private Function isFaceBookOpen() As Boolean For Each ie As SHDocVw.InternetExplorer In New SHDocVw.ShellWindows() Dim filename As String = System.IO.Path.GetFileNameWithoutExtension(ie.FullName).ToLower() If filename = "iexplore" Then
[code]...
And added reference; Microsoft Internet Controls (COM tab) but i also need to add this reference; Microsoft.mshtml (.NET tab)
Problem is that i can't find that reference. BTW, I want the function to be triggered by a timer.
I have a Access program and I'm using VBA code in the background to run Winunzip using shell command. Well, the path of the .zip file has spaces in it and it's not recongizing the path as a valid path. Is there a another way to tackle this problem besides the shell?I can't us pkzip either. Has you can see I had to use progra~1 instead of Program Files.[code]
Im trying to write to a file I created and place "Unregistered" in it. Thought it would be a simple task but keep getting an error. Its happening when I try and open the file to write. This is the error: Access to the path 'G:\Projects\Project\pbss\bin\Debug\5\pbssv\Data.DB' is denied.
Ive tried adding the file attributes to read-write and still get the same. Most of the code ive looked at via a google search points to the same as ive got for the Added default value area. Im not sure if there is a conflict between the 2 different ways im accessing the file when creating and writing too? [Code]
I am having trouble uploading any file to the path in the error message below. Does anyone have any idea what the problem is. I did some research on this and most sites say that the permissions need Read/Write access for the asp.net user. I tried this and I still receiver the error. Here is the error:
For example Error saving file education_calendar.pdf System.IO.DirectoryNotFoundException: Could not find a part of the path "d:inetpubaophaUploads". at System.IO.__Error.Here is my code for the click event. I am not sure what is happening here:
Private Sub cmdUpload_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdUpload.Click If IsPostBack Then Dim MyFileColl As HttpFileCollection = Request.Files Dim MyPostedMember As HttpPostedFile = MyFileColl.Get("File1")

I need to open a *.py file in the shell (DOS) box, but it returns an error that no file was found at the specified path. But this path is completely correct. Unless Visual Basic are referencing to paths in another matter than C#? 'Cause I am developing in C# and referenced to VB to do this.
I'm using Microsoft Visual Basic 2008 Express Edition. I have a Folder Dialog Browser added in my form and I call it when the user presses a button. The folder path string is stored in a string variable and displayed as text in a text box. (maybe I should use a combo box)
My question is: If the user inputs by hand a non existent path, how do I return an error message, stop the file creation into the invalid path, and return to my main form?
I am trying to delete the song node from the xml file but i can't figure out the cause of the error I'm getting. I'm still learning visual basics. Error: Object reference not set to an instance of an object. This is my code
I am receiving this error: Reference to a non-shared member requires an object reference on the code I've bolded within the code body. Here is my code:
I get this error:Reference to a non-shared member requires an object reference.When i compile on the following code section:
Private Sub statusBarToolStripMenuItem_Click(ByVal sender As Object, ByVal e As EventArgs) ToolStripMenuItem.Checked = Not ToolStripMenuItem.Checked statusStrip1.Visible = ToolStripMenuItem.Checked
I am opening frmB (variable for FormB - the actual form) from frmA. From btn1 I open frmB like this:
frmB = New FormB() frmB.Show()
From btn2 (frmB is already open) I bring frmB to the front from behind frmA:
FormB.Show() FormB.BringToFront().
No problem so far. Now I need to pass an arg to frmB. This is where I am having the problem.
from btn1 (in frmA) I do this:
frmB = New FormB(myArg) '--pass myArg to constructor of FormB -- no problem here frmB.Show()
then from btn2 -- this is where I have the problem
FormB.Show() FormB.BringToFront()
I tried placing myArg in FormB.Show(myArg) but that did not fix the problem. What is the correct way to pass myArg to FormB (frmB) in this scenario? Do I need to share FormB or frmB? How do I do this? "frmB" is frmA level variable.
