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!
On forms size and such, is it in points or pixels? I'd assume pixels, however, it seems when i make a image that is in the same size, (i put the size as the dimensions for pixels), the image seems not the same size. I'm unsure of how big a "point" is, but i am aware of a pixel.

View 1 RepliesHere's my scenario:
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 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)?
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 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?

View 6 RepliesI 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',
View 3 RepliesI have a form that starts at a specific point (the right side of the left screen on an extended desktop). I am trying to work with users with different resolution. Insteadof changing the resolution to match the application, I want to try and get the size of the desktop (1280 x 2 for an extended desktop, 800 x 2 for a different resolution) and set the form to the same point... the inside (right side) of the left screen on an extended desktop. Is there a way to tell how long the desktop is from left to right and top to bottom?

I'm new to VB in Visual Studio 2008 and am just trying out some simple test.I just want to change the Font & Boldness of some text but get the following errorProperty 'Size' is Read onlyI have been browsing the forums and it seems that changing the font size etc isn't as simple as
TextBox.Font.Size = 12
TextBox.Font.Bold = True
Is this true, and if so what do I need to do
I'm trying to make a -what i thought would be simple app.My intention was to build program that:1) i'd provide a grayscale image2) the program would count the black pixels the grey pixels the more grey pixels etc. (the hue) and the white3) would make the percentage sum of all pixels, that is: 300.000 black pixels (rgb 0 0 0) etc. given that 0 is the black, 100 the white. e.g a simple grayscale image is 55.2 white
This was my way and i don't think that is useful:
First of a button to convert the image to greyscale:
Dim bm as new Bitmap(source.Width,source.Height)
Dim x
Dim y
[CODE]...
Secondly, -and that's the stupid way- i did -or better i wanted to do- this: i put the code to dynamically create labels, each label having the colour of a pixel as background colour and as text the colour converted to rgb
The third step which i intended to do (i couldn't get pas two) was to sum up the labels etc.
I am after a property that makes a control (textbox, datagrid or other) move according to the forms size. Because some of the controls I got does that, and I really don't want it. I've been looking at them but could not find it
