I have a database application in which a user can add up to 6 pictures to each record. This pictures are not directly saved in the database but in a sub folder of the applicvation folder. Now, the problem is that lots of the pictures of users were taken on a digital camera with highest resolution - in these days it means that the picture files have a file size of 3MB.I would like to reduce the file size / resolution of the picture, so that the database can load and view this files more smoothly (I am not in need of a thumbnail preview, just want the pictures being a bit smaller).
The way pictures get attached / linked / 'inserted' to a database record is via OpenFileDialog. When a user selects a picture file it gets copied into the applications picture folder and renamed to the record ID of the actual record + number of the pic added.How could I reduce the picture size during adding it (OpenFileDialog / copying to folder)?
how to reduce file size? for example : i have a video file that size 13MB now, i want to make the video become 500kB even if the video become shorter thant the original. because i just want a little size of it.
1) The user places a handful of image files into a given directory. Could be bmp's, jpg's, etc.
2) The images files will be saved into a 2nd "temp" directory and reduced down to a size reasonable for e mailing (ie. 200kb per file). I'm assuming they will end up as jpg's, so if they start out as bmp's they will need to be converted.If they start out as jpg's, and are just too big, they will need to be shrunk proportionately (ie. if they start out as 12 inches by 18 inches, they will end up as 6 x 9, or something like that).
I've found various bits of code on this forum (and others), but want to hear some opinions about the best way to go about it, assuming there might be as many as ten or twelve files that need to be manipulated. So should I read something into a memory stream (haven't tried that before), or create bitmap objects (seems slow?), etc.
I like to compress the xmldata before the data is provided to the client as an excel file. I am trying to compress and deliver it as a .zip file. its not working Here's my code below. I tried compressing it, converting it to bytes etc etc. The issue with below code is, the XSL transformation is not happening properly and the output excel file is raw xml with some .net exception at the end. (that's what I see on the .xls file that's downloaded at the end) Before I started working on compression my below code was working fine that gives properly formatted excel file from the xml input. the excel file is so nice you can't even tell it was from XML.
I want to programatically delete some pixels that are unused in order to reduce the image size.Can anyone tell me how to reduce the size of an image file without changing the pixels values..
I am working on an program and I need it to change the size on the form and the button etc when its ran on a different resolution then it was coded on. Is there anyway to do this easy or do I have to hard code it on two different and change it by like a button etc? I am working with a 1024 X 780 and a 1240 X 1024.
I have a system in VB.Net 2003, and that system takes a very long time to load. From the minute I click on the EXE, it takes one minute before the log in screen appear (P4 with 1GB RAM, no other application running). The size of the EXE is 33.2MB. I think the problem is the way I code the program, 1) I declare all the form as obj when I first load the system and I've got over a hundred forms. I try to load them as I need them but it does not work cause forms with sub form would give me an error. 2) I am using dataset as we know dataset is not very efficient but I don't know how else to connect to the database. Is there anything like ADODB in VB6?
I am using VS2010 and have an application that lets the user search for an image to store on a SQL database. I want to be able to reduce the size of the image when it passes certain size for obvious reasons.
I have a database designed and implemented using ms sql server 2005. initially, the user has entered the pictures with a very big size because there was not restriction. now when the user is opening the crystal report so it takes alot of time and some time memory full problem occur. now i want to reduce the stored images size using vb.net. is it possible? can you help me.. because there is nothing impossible as per my experence.
That's the function i coded to reduse the quality of an image but its a complete FAILURE it doesnt even make sence (It firstly takes a screenshot of the desktop)

How can i achieve a ( 800X600 / 256 Colours ) Image to have the lowest file size possible? Yeah 70KB --> 30KB makes a HUGE! difference. 30KB IS PERFECT!
I have a big windows forms project I'm working on. This project has 3 pictures included as resource. I had 3 pictures of each 5mb, which resulted in a .exe file of 17mb. This had to be adressed, because thats a bit to much, so I downsized the pictures to about 100kb each. I've removed the big pictures, and inserted the new ones. But when I compile the project, the .exe file still is 17mb, and it won't get any smaller. I've tried to 'Clean Solution',
I am working with vb.net and want to increase the size of image when the cursor is over that image, but the image should come back to its original size when the cursor leaves that image area.I've used the following code to increase the size of image:[code]I've used the default size class but, it gives some different dimensions.by the code that brings the image into its original size that I've been declared into the picture box properties.
Wondering if there was a way around the seemingly nonsensical editor changing of the maximum size form you can edit/create to some value approaching the screen resolution you are working on. This is a P.I.T.A. as I often edit pages on a laptop with a smaller max resolution than the monitors I typically do layouts for.Any way to by pass this to let me edit larger screen sizes on my laptop?
as i said earlier i am working on an program called logon screen changer xp
in a folder i have 2 bmp files i want only 1 but i dont know which so i want a vb.net sample code which searches bmp files in a folder according to the resoltion
I have found some sample code online to use in order to access my webcam, and all is fine. The only problem I'm having is how to set the resolution of the camera. Any ideas where Im going wrong? I think im getting 100 by 50 at the minute. Im trying to set it to PictureBox1's dimensions now. [Code]
I am trying to split the image into 9 equal regions , and the below code does it well the problem is i want to get the selected image size and not picturebox sizeso what should i change to get the selected image size instead of picture box sizei dont want the picture box to grow in size with image because it will hide other buttons/textboxes etc
Dim xi As Integer = (PictureBox1.Image.Height) Dim yi As Integer = PictureBox1.Image.Width Dim px As Integer = xi / 3
I just want to get opinions from other developers.What size do you tend to prefer for your applications?I have decided to stick to 1024×768 but am I alienating the people who still have 800×600.According to Wikipedia only 1% of internet users still use 800×600 screen resolution.What size do you tend to prefer for your applications?
<Visual Basic 2005 + SQL 2005>I am developing an Human Resource system that has to have a pictue image for each employee. I can't ask HR person that takes a picture and reduce it to upload to the HR system.
I am new to this forum, and have search both here and on the interwebz.I don't have my code here right now, but thought I could ask anyways:I have an application that is going to run in fullscreen and display a clock in a defined position on the screen when it is in fullscreen mode. How can I define that position so that the clock appears at that point regardless of resolution on the screen?
I have just found that if a DataGridView image column's size (height & width - in pixels) is smaller than the image's original size (in my case all images are exactly 180 x 180 pixels) at the time the cell is populated then the image is automatically being converted to a lower resolution I assume to fit the image completely within the size of the cell). How can I stop the automatic scaling of the image?
The image below show the same file displayed twice, both at 60x60 pixels ('Thumbnail' column) and a blowup of the image (PictureBox populated via the CellMouseEnter event) to it's right. You'll notice the resolution of the first blowup is far less the the second. so, what made the difference in the resolution of the blowups is? In the second blowup's case I'd first stretched the image column's width to ~180 pixels and set the row height to match (via the ColumnWidthChanged event) then populated the DataGridView then stretched the image column to 60 pixels (its minimum).
We did development of a VB application on a machine with a high resolution screen. Also the machine where the real application runs has a high resolution screen. After a while we wanted to do minnor changes on the application and we wanted to use a low resolution laptop for that. When we opened the application for editing we saw that all forms changed their sized automatically AND unwanted.How can we build and change applications in one form size that does not change depending on the resolution of the machine on which edits are made?
I created setup file by setup project. I attached with mdf, ldf files in it , SO CAPACITY OF IT AFTER PACKING IS QUITE BIG.I want to reduce its capacity. How can i do that I see some other Setup projects which have attached with mdf ,ldf files but It is not big as SetUp file of me.
