Normally when user upload a picture, how do u control the size of the picture uploaded by the user?
is there a way to change the size picture (scale the image according my size 300 x 150). Let say an user upload an image with (500 x 300), using picturebox, can i scale the image (500 x 300) to my picturebox size so that it can looks perfectly nice?
Does anyone has a sample code or idea for cutting and adjusting a picture size when it is uploaded thru picturebox?
For example..
1. Picturebox size on winform = 150*150
2. A picture size = 1024 *800
3. I want to be able to cut 150*150 out of 1024 *800 and upload it. I wish the cutting and adjusting size is possible thru winform.
I've been reading gobs of articles on FTP upload in ASP.NET recently and they all seem to make sense, but every time I've tried implementing them I either get an empty file uploaded, or no file at all. Here are some of the articles I've been reading:Managing FTP Transfers from an ASP.NET Web Page By John Peterson FileUpload Control Doesn't Give Full Path...How to: Upload Files with the FileUpload Web Server Control I know exactly what the problem is but I don't know how to fix it. I can pass the file name from the FileUpload control, but the path does not exist for security concerns. However, the StreamReader object requires the fully qualified path of the file to be uploaded, so how the heck do I get that? I'm at my wits end!Let's use the example by John Peterson that I linked above. Here's the code:
Protected Sub btnUploadFile_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim myFtpWebRequest As FtpWebRequest
Dim myFtpWebResponse As FtpWebResponse

I have wondered the solution to this question for many years! I doubt if anyone else knows much about it because the internet is absolutely zero help in this!
I have made a form1 with a webbrowser control on it. When the program is run it brings up the homepage (which is Google). However the homepage doesn't seem to fit inside the webbrowser control.
So I am hoping that someone could tell me how to make the (...I dunno how to ask this retarded question...) webpage fit completely (100%) inside the size of the webbrowser control. Meaning...I would like to see the entire webpage from the internet in the
size of the webbrowser control. To fill the entire size (whatever size I want).
Etc... if my webbrowser ontrol is seh, set to 600px by 400px, how can I program this so when it brings up the homepage (or any other page), it fills the entire size of the webbrowser control? Without any scrollbars. How to make the contents from the web
(or local) fill the size of the webbrowser - almost like a mini browser if you will.
I have a picturebox with a tiled background image (plane white bitmap), and an "image" resource centered in the middle of it, I would like to chance the size of this centered image within the picturebox.
I tried:
picScaledRepresentation.SizeMode = PictureBoxSizeMode.CenterImage
picScaledRepresentation.Size = New Size(Width, Height)
But this just changed the the size of the whole picturebox, rather than the image within it.
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
View 4 RepliesI'm writing a couple of custom controls in VB.Net 3.5, in VS2008, and would like to resize the font size based on the height of the control, and vice-versa. Is there any way of converting a font of say 38.25pts into a me.height, or the other way round?
I realise the font width will change dependent on the font used (which isn't an issue for my purposes), but as far as I know, the font height is usually consistent Accessibility/Large font settings won't be an issue with this application.
somebody provide an exmaple on how to change the size the of the picture i.e to zoom into a picture at run time for eg: by selecting 100%, 125 % on a menu
View 6 RepliesI have some custom user controls in my .net winforms program that do not display correctly when the user has selected larger text size. This setting:
My controls look like this:
Instead of like this:
The bill to area and ship to area are both custom controls. I don't know if this is contributing to the problem but I do have code in each to scale the phone/fax areas to stretch nicely, like this code from the bill to control,
Private Sub panFaxPhone_Resize(sender As Object, e As System.EventArgs) Handles panFaxPhone.Resize
panFax.Width = (panFaxPhone.Width / 2) - 1
panPhone.Width = (panFaxPhone.Width / 2) - 1
panFax.Left = panFaxPhone.Width - panFax.Width
End Sub
How can I get my controls to size correctly while still respecting the users choice for larger text (I don't want to just set the AutoScaleMode to None)? After playing with this for a long time it seems to be a problem with anchors in the child controls. See this below image, the inner black box is the control with its border turned on, the text boxes (like name) are anchored left and right and should stretch to fill the control, but don't.
I want to develop a small utility that can resize some of my png's in bulk to a common size say, 400 x 400 pixels.
View 1 RepliesI 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 have a site that has a profile page and I would like to allow the users to upload an image for the profile picture. I forsee a problem if the user select an image that is larger than what I am allowing for the site. Is their a good refrence or example how to accomplish this?

As an update to a program I had made awhile back, I am trying to auto-resize the image to meet the requirements of my application without having to manually do it elsewhere. I already can adjust the quality/compression for disk storage, but I want to resize the image so I can save the quality of the image.
So how do I resize an image to 1920*1080. (I want to check the image first to make sure that the image is in fact larger then 1080p before I resize it.)
I'd really like the solution to work in a DLL project so that I can move my application from the Windows Forms to the WPF UI.
how can i call a VB function - deleteevent() in usercontrol.ascx.vb from a javascript function in clickhandler(e) in usercontrol.ascx.

But i dunno how to call the click event.
View 2 RepliesMy plan is to use a database to hold her recipes and create a user interface with search controls and different stuff, this way she will be able to add new recipe's and the program will have a much more modern feel to it.
My question is, I have added a picture box control to the new recipe form and when I click on the picture box I want the program to load "my pictures" and let me select a picture to load into the picture box, like you can on ebay when you are selling stuff, you can select your picture and it loads into the picture box.
As far as starting this off, I can add a double click event on the picture box control, this will trigger whatever code I need to use to load the open file dialog.

I am trying to build a tournament bracket application. In order to build the application efficiently I would like to make a user control "GameControl" that represents a game and give it attributes that represent the names of the competitors "TeamNameA" and "TeamNameB" ,an attribute "Winner" to represent which team should move on, and an attribute "NextRoundGame" that assigns another instance of the user control so that it can assign the "winner" to one of the "TeamName" attributes of the next round in the competition. If the controls were native to VB I feel like I could do it easily (I have only spent about 30 hours self teaching/tutorial following) but I can't seem to find out how to pass values to custom attributes of custom user controls through code.
