I have a windows application that dynamically loads DLLs using Reflection.Assembly.LoadFrom(dll_file_name_here).
It works as expected, until I ILMerge the application with another DLL.
So this scenario works fine:
MyApp.exe
MyAppComponent.dll
Plugin.dll
Once I ILMerge MyApp.exe and MyAppComponent.dll resulting in:
MyApp.exe
Plugin.dll
Calling Reflection.Assembly.LoadFrom("Plugin.dll") seems to load successfully, however once I try to do anything with it eg:
foreach ( typeAsm in Reflection.Assembly.LoadFrom("Plugin.dll"))
I get an exception "unable to load one or more of the requested types. retrieve the loader exceptions property for more informtion".
The frustrating thing is I can't really debug it, because debugging pre merging works perfectly!
I have started a new blank project for VB 2007. I have taken the old code (VB 2003) and added it to the project.The line marked below worked on the old VB, now it does not. I get the following error:
Object reference not set to an instance of an object.
Troubleshooting tips:
Use the "new" keyword to create an object instance.
Check to determine if the object is null before calling the method.I have tried several forms of using the "New" keyword and still get the error.

View 2 RepliesI am dynamically adding a link button to every cell in a gridview. Adding the button works however the firing of the even handler doesn't. i need the linkbutton to call a function and pass some data for processing. My code is below. I have found solutions from the site that have gotten me this far.At the moment the gridview loads the cells with buttons in blue. when you click them they go back to plain text and no function is called.

I have a linkbutton that is nested in a datagrid that is nested in a datalist (yes, very strange, but unfortunately it's part of the site which I cannot change). Essentially I want the linkbutton to fire an event handler that calls Response.Redirect(e.CommandArgument)). In other words, I already have the URL that I want to redirect to, but I can't figure out how to get the event to trigger when I click on the linkbutton.
I have tried using the linkbutton OnClick events and the ItemCommand events for the datagrid but I dont think I am registering them correctly.
[Code]...
This is my latest attempt where I am trying to get the datagrids ItemCommand to fire when the client clicks on the link, but it's not working at the moment.Failing this, is there an easier way to redirect the client to the correct page when they click on the linkbutton? I tried using the OnPostBackURL but the issue is that there are objects that need to be carried over that dont seem to be when I do this or when I just use a hyperlink with navigateurl set.

how can i call a VB function - deleteevent() in usercontrol.ascx.vb from a javascript function in clickhandler(e) in usercontrol.ascx.

In VB.NET, I have a LinkButton that, when clicked, creates a report. We want to disable this functionality based on whom is logged into the system. I have a session variable to indicate whether this should be visible or not but when I set idLinkButton.visible = False, it has no effect. Any ideas on what I need to do to be able to turn this on and off?

i have created a dynamic tabpage and a dynamic tablelayoutpanel inside it then added dynamic textboxes and labels inside the tablelayoutpanel...the thing is , i am having a problem on how to access the value of those textboxes and labels and add them as new columns in the new table(tagpage) in mysql database, i can already create the table in the database but i cant add the new columns in it. heres the code for accessing the values of the labels and textboxes

I would like to bind a DataGridView to a different LINQ query every time (in order to reuse the same form/DGV for different queries), like this:
[Code]....
but the "Qry", and the number of comboboxes, and their field names would change every time.
Basically i have one TabControl with a form and 2 browsers within one form I have ProBlem To call the dynamic browser to navigate with dynamic Textbox.text
[Code]...
I need to represent the following query using LINQ:
DECLARE @PurchasedInventoryItemID Int = 2
DECLARE @PurchasedInventorySectionID Int = 0
DECLARE @PurchasedInventoryItem_PurchasingCategoryID Int = 3
DECLARE @PurchasedInventorySection_PurchasingCategoryID Int = 0
[code]....
Now, I know that a query in .NET doesnt look like this, this is my test in the SQL Design Studio. Naturally VB.NET variables will be used in place of the SQL local variables.My problem is this: All of the conditions after "WHERE" are optional. In that a query might be made that uses one, some, all, or none of the conditions. V.PropertyID and V.Value can also appear any number of times.In VB.NET I can make this query easy enough by simply concatenating strings, and using a loop to append the "V.PropertyID/V.Value" conditions.I can also make a Stored Procedure in MS SQL, which is easy enough.However, I want to accomplish this using LINQ.
Ive managed to dynamically create a form, and dynamically create a timer, but i have not been able to create the timer on the dynamic form. Specifically, i need to be able to have the timer itself create another form with a timer. (I realize that this would create a new form every interval on the timer, that is what i want to do)
1. A way to add the timer to the dynamic form, and maintain the timer sub on my main form.
2. A way to create the whole thing over (dynamic form and timer) through the previous dynamic form and timer.
I was thinking i could use a collection/array to store the forms and timers, but i'm still having trouble figuring out how to add entire forms or timers into a list. (A timer is not considered a control, so i cant use a controlcollection...)
Heres my code;
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim frm As New Form
[Code]....
*EDIT* Btw, my idea was to use i as a variable that increases every time a form is created, then insert the form into the array, with i as the integer. i just need to know how to create a new form with a different name each time. (as with timers)
I have a form that i need to be 100% Dynamic. So it could contain 10 labels maybe 100 who knows.
When you hover over a label there will be a different contextmenustrip to appear for each and every label. So all the contextmenustrips are Dynamic and contain 1 option maybe 2 options even 3 or 4 up to the users settings.
My problem is not creating a handler for when the user clicks on the contextmenustrips options. The problem is knowing which one of the options for that contextmenu was clicked!!
OK, I'm trying to display tooltip text for a dynamic edit box. Well, at least I'm trying to.
On my form, I've got a tool tip control which I've conveniently named ToolTip. My edit box displays OK. But, what I want to do is when the user hovers their mouse over the text box, I want the tool tip to display some text.
I think there are two problems that I'm having. I'm not convinced that I'm properly addressing a dynamic text box name. Ideally, I would want to be able to refer to the text box (but using a dynamic variable that will contain the prefix of the name). To hardcode, I would want to be able to achieve (not in this example but in theory): ABCDEFGt_0300.Text = "hello"
Dim controllerName as string = "ABCDEFG"
Dim t_0300 As New TextBox()
Me.Controls.Add(t_0300)

It appears that my favorite thing in the world is tackling projects that are beyond my current knowledge and abilities. I have a little project that I am working on which is a simple image viewer stocked with (upon completion) your standard Load..., Next/Previous, Zoom In/Out, Actual Size, and Full Screen capabilities. However, I am running into a few snags:
(1) I've been able to get my "Load..." button to display a file dialog box, but I cannot seem to get a working filter (with which only image file types are allowed to be selected) in working order.
(2) I have a PictureBox object (entitled PictureBox1) that displays the image selected via the file dialog box, but it loads images in their full size (1:1/100% zoomed) state without scrollbars, etc. to allow me to navigate the loaded image. I would like to have it load the image, initially, to fit within the dimensions of PictureBox1 and from there be able to zoom in/out via my "Zoom In/Out" and "Actual Size" buttons and be able to scroll if the zoom level is beyond the dimensions of PictureBox1.
(3) It dawned on me that I haven't the faintest idea how to get my "Next/Previous" buttons to allow the user (me) to navigate, in succession, the images contained in the folder in which the currently loaded image is stored. [code]

Below you will find a code sample that I have dummied up to try and demonstrate the issue I am having. However, this is just a dummied up piece of code. The actual program has noting to do with STUDENTS or TEACHERS. Basically, the problem I'm having is trying to have a CLASS within another CLASS each of which contain ARRAYS that need to be dynamic in size. The sample has a CLASS called STUDENTS that can have in theory many students, the number of which are unknown to the CLASS. I need to be able to add STUDENTS to the ARRAY programmatically.
The CLASSROOM Class should also be an Array since each TEACHER will have MANY Students. There will be only 1 Teacher for a given classroom but the SCHOOL will have MANY CLASSROOMS. Again, I need to programmatically add Teachers and Students without having predefined Array sizes. The code I have listed below will NOT work but it demonstrates what I am trying to achieve. I want to be able to reference the CLASS by using something like this ...
School(iTeacherIndex).Student(iStudentIndex) = "Rick Smith"
I feel like I should be able to use ARRAYLIST in both classes but haven't been able to get it to work. I've tried DIM'ing as ARRAY and can't get that to work either.If I can get ARRAYLIST to work then I shouldn't need to worry about expanding the array via UBOUND (if it's even possible).The REAL question is "How do I have a CLASS within a CLASS, each of which has ARRAYS that need to be dynamic in nature so they can be expanded as needed? The size of the array cannot be determined ahead of time".
REMEMBER . . . the actual program has nothing to do with Students and Teachers. This was just my way of demonstrating the issue using an analogy that I thought everyone could understand. The actual Class is much more involved.I have purposely hardcoded some values just to make the sample easier to work with. This is NOT how I normally program but is just here to hopefully make things a little more clear.
Here is the sample code . . .
