1. Is it possible to store images in the variables or something like that, then store the images of things that are not buttons, picture boxes or panels?
2. What is the fastest way to store images in Visual Basic?
3. Is it possible to create a list of the class Bitmap and post a picture in each bitmap in a forloop? If it works I would like to see some examplecode.
How to store and retrieve images from VB.NET and Sql Server 2008
View 9 RepliesWhich is the best way to store global variables, in My.Settings or My.Namespace. The reason I ask is because I need to know certain boolean values if certain forms are open from other forms. At present I am defining Global Boolean variables in My.Application, which give the result I require.

View 2 RepliesI am using sql in and am stuck. after "selecting * from table", how do i store whatever I have obtained from my database in a variable, for display?
View 2 RepliesOk so here's the story. I have an array of Assemblies which are initiated by [Assembly].LoadFrom() that load a number of DLL's. Upon initialising, a method called InitMain (from the DLL!) is called, which sets a number of variables outside of this method, like here:
Public Class Example
Dim C As Integer = 0
Public Sub InitMain()
C = 50
End Sub
[Code]...
If I call the method Test using that same array of Assemblies somewhere later in the main application (like pressing a button or something to trigger it), it will pop up a messagebox with that says: "C = 0"Why is this? Is it fixable without any odd workarounds?
I have a database in my app which loads and displays some information on a form by binding the Comboboxes and Textboxes. However, I need to get some of the other values from the database for calculations before they are displayed on the form and I can't seem to find out how to do this.I could bind a couple of Textboxes to the database and then use those values to calculate, but it doesn't seem like a very efficient way of doing things.The dataset is created using the wizard and the controls are linked in the UI.
Please bear with me, I'm still a noob.
How do i store and call images in a SQL database?
View 4 RepliesAt the moment each Company on my website have 1 picture they can add to their profile.I save that image into the database.its their Company Logo.Now i want to allow them to add more pictures. Now i don't know if i must save it all in the database or save it in folders???? Reason why i think folders will be better is because there are so much nice articles with fancy silver light kinda features that i can use but all of them only cater for images saved in folders.And since i am not THAT good its hard for me to change the code to look at the database instead of the examples that uses folders for image retrieval.I would like to add something like this to my website (browsing through the images).Any code examples for me on how to do this when images are saved in the database? I am using ASP.NET with VB.net.

View 3 RepliesI need to send up to to selected images (such as an apple) to pictureboxe's on a results page. at the moment I'm using global variables to attempt to display the images like this:
Me.pbItem1.Image = New Bitmap("images\" & gstItem1 & ".jpg")
Me.pbItem2.Image = New Bitmap("images\" & gstItem2 & ".jpg")
I get a directorynotfoundexception 'Could not find a part of the path '\images\apple.jpg' error. I'm new to VB and think this must have something to do with the default path or something.

store and retrieve image in a SQL Server database with vb.net.:Well, the application in vb.net seems to have a database which can accessed by the LAN computers so the SQL Server 2005 database allows remote computers to share its database once the other computer application requests database from the server.So, every other computer has to store and retrieve images in SQL Server 2005. For example, comp1 has to store images taken into the server and retrieve it like tableadapter.
I am using bindings and tableadapters to store the details in database and retrieving information from db. Please if you have code or anything which is working for me, please post it here... how to store image and retrieve it SQL Server through vb.net provided there's LAN computers who are also sharing the SQL Server database.
My text file is a settings file and I know I will be adding more to it in the future, right now it reads "autoplay=false;mintray=false;"I am currently using probably the most inefficient way to check both of those settings:
if contents = "autoplay=false;mintray=false;" then
elseif contents = "autoplay=false;mintray=true;" then
elseif contents = "autoplay=true;mintray=false;" true
elseif contents = "autoplay=true;mintray=true;"
endif
How can I read the file, find each word from the equals sign to the semicolon, and store each of them in a variable identified by the text before the equals sign? Something like this:
contents = "autoplay=false;mintray=false;"
autoplay = "false"
mintray = "false"
Also, how can I edit the settings in the text file without having to overwrite everything every time I save to it? For instance; finding mintray in the text file, and changing mintray to true instead of overwriting the file with "autoplay=false;mintray=true;".
This is my current

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.
The app i am working on is for creating theme for the iPod touch... It has to deal with LOTS of images (100's potentially) There will be the set of default images, and then the user created replacement images. I started loading all the defaults into a resx file... thinking then I could just pull them out. now that I started setting the default, this sucks! lol the app will do this, on load it will set all the images (variables) to the resx images then when a theme is loaded, it will replace the default with the user image (if the user img exists) otherwise, the default stays. Then the "screen" is drawn to show the user. so, here is just the images to build the wallpaper, dock, and status bar...

I need this for my program. There is "add images" button where you can load multiple images and those images should be show on listview after loading.I have been trying to make this but could not get it work.
View 6 RepliesI am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.

In our projects we use setting variables to store user setting for the applications. Moreover, with every latest version of the applications, we upgrade these variables to retain user settings.Normally, this works fine, but recently one of my end user reported an error i.e.Configuration System failed to initialize". The error is related to user.config file. Therefore we requested the user to send us his file.After received the folder, we noticed that it contains 3 files (3begfjb.newcfg,3begfjb.tmp and user. config). 3begfjb.tmp is an empty file, while 3begfjb.newcfg and user.config are identical files. We tried to open these files but the data in user.config isn't proper xml rather its unreadable formatted file.Do any you guys had experienced this sort of issue or any ideas how and what may have created these files and corrupted user.config file.

View 15 RepliesI 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.)
