I'm trying to recreate this feature for a twitter control program using VB Studio 2008. I want the users to be able to sign up their account in my application so they don't have to go to the site and do it.
Because captchas are dynamic images, I cannot pull the image from a src file. I'm pretty new to vb.net so, how would I initiate a session, with the webbrowser control or webclient, and be able to display the captcha image for that session on my form.
I am using Vb express 2008 and MsAccess as database.I have developed code for Sale of Point. Now i want to do some grafic effects on the form.How can i put an image(such as Logo ) in a picture box on form. I tried to load the image of type JPEG and when i load it in the picture box it does not fit into the picture box it is too large to fit in the picture box.Also i want to display this Logo as background image on the whole form.
So my program is supposed to lookup the image name from a database and display it in the form. Here's the
name = rs.Fields("image").Value.ToString If Not IsDBNull(rs.Fields("image").Value) Then If rs.Fields("image").Value = "" Then Else PictureBox2.Image = Image.FromFile("\MY.IP.ADDRESS.HEREwwwrootimagesproducts" & name & "") End If
[Code]...
Now here is the problem: If the database returns the image name but the image cannot be found in the path specified, the app crashes. Is there a way to write an If statement to check if the image file exists in the directory specified?
I am designing an app and I want to attach some pictures to my VB forms. I have used a picture box and the image is only visible before I debug. Once debugging starts, the image disappears.
How do I display the image when I run the debugger?
I'm using VB 2010, accessing a MS Access database. I have constructed a simple Windows Form returning data from the db, one field of which has a reference to an image I'm trying to display together with the data from each individual record.
I have a field with a product number, that matches the jpg file name (ie, the product number 5505 matches an image that I want to display, namely 5505.jpg). I've even created a new field in the db called 'Image', that contains the full name 5505.jpg.
So, I've connected to the db with an OleDbAdapter, and all the data fields are displayed via bound textboxes. I've been able to display a single 'set' image with a PictureBox, but I'm not sure how the make the connection between the returned data (txtSearchImage which is, say, '5505.jpg'), and getting the Windows Form to display this.
Am I on the right track using a PictureBox? I've tried binding this via the PictureBox properties to the relevant data field, but (obviously) it doesn't make the connection to the image file on my hard drive.
Here's my code so far:
Public Class Form1 Private Sub btnSearchKits_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearchKits.Click ' The following line passes the value the user enter for state
For comparison: something like the shirt builder application at [URL]Say, if I have fabric image and want to generate base, collar, cuff etc. How should I do it on server side in .NET, and generate different components of shirt.
I've been trying to make an image viewer that keeps top most while I do other things (like typing, etc), so I don't have to hop windows, or sacrifice screen real estate.I made a main form, and a configuration form (opened by pressing o), with options to set the main form's opacity (working), the picture displayed (as the form's backgound picture, not working), and if the main form stays top most or not (working).
Instead, the form just keeps displaying the image I set in the IDE.I first used a picture box to display the picture, which did not work, and decided I didnt need to have a picture box if I set the picture as the form's background picture.I tried looking at what could be going wrong, but couldnt find out much more than the path is being delivered to the main form.I'm working on Vista Home Premium 32bit SP2, VS2003, and here's the code.PS The code links to a D:ath-fin.jpg that I used as the default background picture, and the code is for 2 seperate forms.

I am an experienced programmer but mainly in 4GLs and assembly. Relatively new to VB programming, especially GUI applications. On a form I need to create an area that will be used to display *extremely* large TIFF images. typical image size would be 2000 pixels by 100,000 pixels. Typically I will NOT want to display the entire image at once, so the area will need to have scroll bars and/or other methods to scroll/pan around the image.
I have read about and tinkered with the bitmap and picturebox objects, including some threads about several different ways to implement scrollbars. However, I see that the picturebox size is limited to 32K pixels in both dimensions. I suppose that I might be able to copy various portions of the bitmap to the picturebox depending on scroll position, but that seems potentially quite slow and cumbersome. Can an expert developer who is experienced with these types of issues regarding the following:
1. Can bitmap objects be used effectively with TIFF images of the size I am working with?
2. an approach that should produce reasonable scrolling performance for these extremely large images without excessive coding effort?
3. For an image that exceeds the picturebox size when displayed at 1:1 scale, is the picturebox capable of displaying a reduced size version of such an image without lots of code, and if so, how?
4. Many (most?) graphics display objects count on all of their display data being stored in memory rather than on disk. Would that be true of a TIFF image loaded into a bitmap object and displayed via a picturebox? If so, the amount of RAM required in order to buffer the entire image in memory could be a potential problem for images of this size. Is there an advisable way to have the picturebox or other display object only load portions of the image into memory on an as needed basis, and purge them once they are no longer required? Are there any built in objects/methods/properties or is there any sample code to show how to do this?
i want to be able to retrieve dynamic data from a web page (share prices). I started out by retrieving the html code before i realised that as it is live data, the html code will be of little use. Although i am looking to capture specific data, all i wish to do is process a webpage that i specify which will return the text off that website and not the HTML code.
Ive managed to dynamically create a form, and dynamically create a timer, but i have not been able to create the timer on the dynamic form. Specifically, i need to be able to have the timer itself create another form with a timer. (I realize that this would create a new form every interval on the timer, that is what i want to do)
1. A way to add the timer to the dynamic form, and maintain the timer sub on my main form.
2. A way to create the whole thing over (dynamic form and timer) through the previous dynamic form and timer.
I was thinking i could use a collection/array to store the forms and timers, but i'm still having trouble figuring out how to add entire forms or timers into a list. (A timer is not considered a control, so i cant use a controlcollection...)
Heres my code;
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim frm As New Form
[Code]....
*EDIT* Btw, my idea was to use i as a variable that increases every time a form is created, then insert the form into the array, with i as the integer. i just need to know how to create a new form with a different name each time. (as with timers)
I have a form that i need to be 100% Dynamic. So it could contain 10 labels maybe 100 who knows.
When you hover over a label there will be a different contextmenustrip to appear for each and every label. So all the contextmenustrips are Dynamic and contain 1 option maybe 2 options even 3 or 4 up to the users settings.
My problem is not creating a handler for when the user clicks on the contextmenustrips options. The problem is knowing which one of the options for that contextmenu was clicked!!
i have a problem with a webservice written in VB.NET. my intensions are to display a fontlist in a website. since the code i found only works in IE (look in HTML forum for the script) i was thinking of a webservice (since i already worked with this. look in PHP forum for more details). while coding i got this code:
how to display and interact with a website, at the moment its just research on how to go about it. Once i start i may need some more assistance. But for now just research At the moment Ive came up with using WebClient and HttpWebRequest/HttpWebResponse to interact with website data. And i know VB.net has an inbuilt site viewer (just a wrapper for IE).The website im using is an Intranet page for doing VOIP calls. It uses a large collection of JS(jQuerry) mostly. I can probably get the dev to make a .php file to
<?php print_r($_GET); Prints all GET variables in a quite readable manner. print_r($_POST); Prints all POST variables in a quite readable manner. ?>
to find out what GET's and POST's there are, but I'm not sure if JS stuff gets put in as a GET or a POST as its in the DOM.So all in all,I'm wanting to make a "Desktop" variant of there client. So basicly just a viewer of the dial pad. And detection of new calls in the queue, things like that. So i want to read data from the website, display the dialpad(just showing a segment of the website) and send the request to accept a call(and maybe a few other small pieces of data).
1) Add a new record - I can currently add records text to access database, but not images.
2) Get the ID [URL]I'm not sure how to integrate this code into my code. I am stuck here.
3) Save the image in the filesystem using the ID as a filename - I can save the upload an image and save the image to a directory on my computer, but I am unable to name the image that of the ID of the access database.
4) Update the database to put the filename in the record you just created. - I am unable to do this as well (obviously).

I need to know how to use listview, I'm having trouble using it.What are listviews uses?What can be listed in listview?What cannot be listview?If an image is in listview, will it display a thumbnail of the image?
I want to create a file upload client for uploading.com and I wanted to know if it is possible to make an application that lets you select a file from your hard drive, press an upload button and then the app will process it just like the website processes the file when you use a browser.Also I want the app to display the progress bar that the website displays when you upload, and when it's done, it has to get the URL for the uploaded file and display it in a textbox.Why not just use the website you ask? Well, I'm planning to make this into a bigger app but nothing will really work unless I get this to work first, so I have to start here.
I want to from VBA in Excel click an image in a website that is not the default image.PageForm.submit takes me back instead of to the page I am trying to get to.
Im trying to retrieve images from a website in my app. Im using the HttpWebRequest to get the source of the site, and then I search the string for <img src=" to get the link of the source.
The full tag is : <img src="shopimages/products/normal/WCA356.jpg" alt="12Pc Stripe Over The Knee Socks (Black/Yellow)" style="width:300px; " class="ProductFullImage"/>
Then I do my little code just to get the actual link name... In the end it will be slink = "http://www.wickedwholesale.com/shopimages/products/normal/WCA356.jpg"
If you go to the link, you will see that the image is a full size image... 300 x 716.
I've tried used the following two methods to get the image :
[Code]....
Method 1 works fine, but looks like the image is saved as a thumbnail. About 39 x 94, instead of being 300 x 716.
Method 2 just doesnt seem to be doing anything, even tho lngRetVal is 46161906918752269.
