In a form I am designing I have a picture box. I want this picture box to display an image from My.Resources. However, the picture to be displayed will change based on conditions. I have written a statement to store the name of the picture I want to call in a string variable called strPicName. So how do I properly use the string variable to get the line of code below to work?[code]...
View 3 RepliesI have code, shown below, that works all except for 1 thing: The variables being passed byRef get passed, but once modified in the else section of the "if me.invokerequired" code of RecordData, the variables are never updated in the calling function. To reiterate, the calling function does not receive the updated data that is in the variables custid and amt.When debugging, I see the data change in the else section of "if me.invokerequired", but once it returns from the callback the data is missing.[code]

I am making a program in vb.net (Vb 2008) but I want to call a dll or add a dll as reference but there's a prob. I don't want to put DLL in same folder of binary like if exe in d:/ so dll will also be in d:/. I want to call it like environ("temp") or from any other which give constant value not in string like ("c:/windows/system32/user32.dll") etc.. Or directory from resources without dropping it out.

I am developing an application where I need to make use of multiple values during the run time. These values are configuration setting of the application as specified by user and are stored in a database (more than 50 in number containing strings/boolean and numeric). I have defined a structure to contain all the variables that will store this information. At start of app, I retrieve all values from database and fill the structure which i can use when required. I am wondering if it is a good idea to declare too much of variables and keep them alive during the run-time as compared to retrieving the values from database every time it is required?

View 2 RepliesLast year (2010) I came across a FANTASTIC command that allowed me to take a string of variables with a common delimiter and break it all back out into separate variables (possibly an array) with one statement.
[Code]...
As long as the delimiter was a unique specifiable character, this one-statement command could break it out into elements. my memory and point me in the right direction.
I define some global variables of a class as follows:
Private Class MyClass
Private var1 as Decimal
Private list1 as List(Of string)[code].....
But I found that after this form is closed, all above variables, var1, list1, list2 still exist in memory. I thought they should be collected by gc since the form is already disposed as I confirmed.
Add: I have monitored half an hour after the form is closed. But these variables are not collected by gc. I have an automatic update procedure on the form which uses above variables.Since the above variables still hold values, the automatic update procedure is always called which causes exception. (One quick fix is to check if form.isDisposed in update procedure. But I do not think this is elegeant. Besides, these variables occupy memory.)
Does the memory used in declaring variables are reclaimed by the OS when these variables go out of scope?Does the memory used be released by setting thier value to nothing? if not, then how can I force the garbage collector to run or excecute at a certain/desired time..How about in Windows Forms..How can we make sure that the memory used in initializing and showing forms be released if those forms were closed?
View 13 RepliesQuestion 1: What is the difference between "Background Worker" and "Worker Pool" as indicated within the MSDN samples provided.
Question 2: I noticed while using, AddressOf _Function_, variables cannot be passed; what would be an efficient solution to this?
Question 3: While using multithreading is it required to invoke before setting variables, or only form properties?
Question 4: While using System.Net.Sockets is it safe/efficient to use Application.DoEvents while waiting for new data; or would be using a Do While loop be fine without DoEvents since the action would be multithreaded? Note: there can be up to 2000-3000 sockets in use at a time.

I've been working with VB for some time using my.resources.I recently installed it on a new computer(Windows 7 ),everything works fine...well almost.
I'm trying to teach my cousin how to change images in an image box using a button.I did it on my computer and it worked,but it wont work on his.Exact same code and images.
Here is what I did:
After having everything set-up I import the 2 images I want to use.
Then inside the click event for the button I write picturebox1.image = my.resources.picture1 "and here is where it doesn't work.It says I don't have any images in my resources named that.Instead it gives me two options Culture and ResourceManager but it doesn't show any of the images I previously imported.
*picture1 is the name of my image
I have no problem with the code(it works),I don't get why it's not seeing the imported images on my cousin's computer.

View 4 RepliesI am a beginning programmer and having a problem with picture boxes and resources which I want to use on the opening screen/form of a program. I have 4 arrays, each with 25 pictures(JPG); I want 4 pictures to appear on the form and to scroll through them using the form load event or a button. The problem however is I get build errors when I have more than 6 pictures in each array. the pictures load if there are 6 or less; more and it's a problem. I have considered some sort of corrupted picture but have changed pictures and get the same result.Is there a limit to the amount of memory that can be committed to resources?
