I am saving and retreiving from textfiles.
Saving the image as an imagepath and have added it to my user structure
Writing :
Retreiving :Code:User.Imagepath = txt_ImagePath.text
however there is an error (syntax blue line) that value of type string cannot be converted to system.drawing.image and I understand that but not sure how else it can be resolvedCode:pbx_UserImage.image = User.Imagepath
What we have here .... is failure.... to communicate.
You've got a picturebox asking for an image. You've got a user object with a string. The fact that the string is the path and file name of an image, while significant, is irrelevant. Becausse that's not what the .Image property of the PB is equipped to receive. It can only receive an image object. So how do you get an image to pass to it? You create a New Image and .LoadFromDisk ... then you can set it to the .Image of the PB. Actually, I think the PB itself may also have a method that allows you to pass it a path & file name and it will load the image for you. Check the documentation on the PB.

Not very helpful at all. Okay the communication isnt the best. Plus I know that what I am doing is wrong however I was wondering if someone could set me on the write tracks. The process you described is easier said than implemented. By saying go check out documentation on PB is possibly the worst feedback I have had from someone as I have actually already done that. Maybe in the feature when someone needs help try to approach it in a better manner than to say "failure" , thanks
Here's the documentation on the PB: https://msdn.microsoft.com/en-us/lib...v=vs.110).aspx
Here's the documentation on the Image property of the PB: https://msdn.microsoft.com/en-us/lib...v=vs.110).aspx -- It clearly does NOT take a string as its value.
Either you read the wrong documentation, or you didn't look hard enough. Next time, link to it, or mention that you checked it out and couldn't make heads or tails of it.
Point I was trying to make was that you're stuffing a quarter into a slot made for a dollar bill... That's a type mismatch. I tried to give you hints... even keywords... such as "New Image" and "LoadFromFile" ... I didn't realize that I also needed to copy those into Google and hit search too. I also mentioned that the PB might have a method to load from a file built-in ... it does. Two in fact. Load() and Load(string). I suggest looking at Load(string). These were easily found by going to the PictureBox entry and scrolling down to the Methods section and looking for something along the lines of "load" and bam, there they were.

still cant manage to work it I dunno whats going on I followed that
im trying the following :
user 1
name = John
Surname = Wallis
ImagePath = C:\Users\Sam\Documents\Visual Studio 2010\Projects\WindowsApplication1\WindowsApplication1\bin\Debug\John.jpg
user 2
name = Tom
Surname = Felin
ImagePath = C:\Users\Sam\Documents\Visual Studio 2010\Projects\WindowsApplication1\WindowsApplication1\bin\Debug\Tom.jpg
Cant have it so that they will be able to save these images and retrieve them when i search their names
all the other details are saved and retrieve fine.
The best Ive reached is that its saving the image but it uses the same image for all users.
Sounds like you have something wrong in your code, but we can't really help unless you show us the code you are using to save and load these files.Quote:

i will be able to see the image of john but when i create tom and with his filepath he will always be displayed in the picturebox for some reason
Code:
Dim UserImage As Image
'Adding[CreateUserButton]
User.ImagePath = Tbx_ImagePath.Text
UserImage = Image.FromFile(Tbx_ImagePath.Text)
'Retreiving[FindUserButton]
Pbx_AdminImage.Image = AdminImage
Module ModuleUser
Structure User
<VBFixedString(50)> Public ImagePath As String
<VBFixedString(20)> Public Name As String
<VBFixedString(20)> Public Surname As String
End Structure
User shouldn't really be a structure. With a size that big, you would be stuffing a whole lot of bytes onto the stack if you ever passed a User as an argument to a method.
However, that's not the issue here. The code you showed doesn't seem to cover the question. You create an image in UserImage, but the only time you assign to an Image property you are assigning AdminImage. Where did that come from?
You probably don't need to go through the step of creating the image. TG mentioned that the PB has a method to load from a path. It's this one:
https://msdn.microsoft.com/en-us/lib...v=vs.110).aspx
So, you can probably just use that and bypass the need to create an image. Haven't tried it, though, cause I didn't know it existed.
Thanks for the input ! definately something im working on
Sorry it should be userimage anything thats admin should be user
dont understand that link sorry i tried to could you show me how ?
Are you saying that this:
Pbx_AdminImage.Image = AdminImage
should have been reading as:
Pbx_AdminImage.Image = UserImage
and that that doesn't work?
That would be kind of suggestive, as the steps all seem reasonable. You get a path, you load an image from the path, then you assign that image to a picturebox. I haven't used that exact code in a long time, if ever, but it all seems plausible. So, if you aren't getting the image, it's time to do a bit of debugging. I'd be placing a breakpoint on the line where you assign the image to the PB. Does execution get there? If it does, then is the image something? If it is, then you are looking at the wrong picturebox by some means, but it's more likely that one of the earlier questions will be answered in the negative.
I managed to fix it not sure what was wrong but the problem I face now is :
If i register you as a user and input your image path : C:\Users\Sam\Documents\Visual Studio 2010\Projects\SystemUser\SystemUser\bin\Debug\UserImages\Shaggy
I can load your image fine (if it was there)
Then if i register me as a different user and input a correct image path
if i search myself and retreive my image it will work
but then if i go to retrieve your record then it will basically retrieve my file path and display my image and its doing the same thing even if i was to introduce a 3rd user. The 3rd user would overwrite our image in picturebox even though its saving fine in the textfile (mine and your image filpath) so i think the problem is with the retreive button (code)
That should probably be a different thread. It seems like it is likely to be a totally different problem. The retrieve button code might be the issue, and that's a good place to start.
ok thanks
