How To Create And Save Thumbnail For Specific File
Jul 27, 2009
Is there anyway to save a thumbnail of an image, then save it so that, when viewed through My Computer, the thumbnail is displayed for the file. Basically, what I mean is to do something similar to the way you can see a preview of a pdf file, or Microsoft Word file, or Microsoft Expression Design file. I want to be able to open the file's containing folder, then switch to thumbnail view, and the thumbnail will be displayed as the image for the file.

I have some code that allows the user to browse for an image and then when that image is opened, it is copied to a new directory. This all works fine, but I would like to know if there is a way to create a thumbnail of this image and save it into a subdirectory inside the directory where the original image has already been copied?

I'm trying to do the following I'm not sure if it's possible using VB.NET. I want to specify default saving point for all files type for example: In my program you choose the path "C:UsersMarkusPictures" for pictures and everytime you download pictures files from website, or using skype or any other program when Save File Dialog opens up (external one not via my program or connected to vb.net just the windows default one) then it will show "C:UsersMarkusPictures" always for .jpg .gif type of files etc...

I have an image upload facility in my asp.net project, when uploaded a thumbnail of the image is generated and saved to disk. What I would ideally like to do is apply some nice styling effects to this thumbnail image.. similar to the look of the icons on an iPhone.. perhaps a slight gradient, smooth rounded corners, and a border.

1.) I dragged my detail view over to the form window to create a bindingnavigator, fields, etc.When I press save on the form, the database is temporairly saved.However, if I save my visual basic project, I lose all the changes I have made to my database.Is there a specific save command that updates the access file permanently?The default command added by dragging over the dataset does not work.
2. My database is accessed with the following string:[code]However, doesn't this mean that the database MUST be placed in that specific folder on any PC? Is there a way to simply build the database into the compile so the program automatically generates the database when installed on anyones computer?
3.) This might be fixed by fixing the previous two issues, but if I compile my program and try to install it, I get an error message "Could not download the application.The application is missing required files."

I want to create a program in vb .net that let me know who is using a specific file? Because I often update an .exe file but if it's in use I can't overwrite it. So if I know who is using the .exe I can call him to tell him o close the app.

That part is already working but part of the requirement is to allow the users to add an attachment to their email.

how to create a save to text file method with a try catch in the method in a class and then call this save method from a button on a window form. I am currently doing the save method under the button directly but to tell you the truth i would prefer to just do it one time and call it from different locations in the various forms i have, then copying it all the time.

I'm new to Visual Basic with no programming in my background. I've created a application without to many problems until now. I've looked around msdn but could not find any tutorial on how to create a "standard" save file dialog box. What I have found is some instruction with a lot of assumptions made such as I've done this before.

Ok so with my program i'm trying to create a save configuration I have it in my context menu so that I can click save configuration and what i want it to do is check to see what check boxes are checked and save those to a file (i.e. a notepad file or whatever works) that way I can save categories for customers or my own computer or whatever and than i'll just click load and choose the category I want and it will load the checkboxes that I want to install. I found a similar post but it's not really making sense to me. So i'm wondering what I need to do to make this work.
I'm also wondering how i'm going to load the configuration but I might have to wait on that one step at a time.

I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .
