View 6 RepliesI'm trying to use a combo box to change the image in a picture box to one that's stored in an external folder. The plan is to, in code, take the part of the file's location that will be constant and concatenate the file name to the end. The file name is stored in a database.

View 7 RepliesDoes anybody know if there is an application that allows us to embed an exe file into word doc, image(JPEG), or PDF.
Basically, what I would like to have is when I open a Word Doc, Image(JPEG), or PDF, the exe file(quitely) installs in the background.
I'm reading a folder to assess the width x height of jpeg's, to classify them in various ways. Opening each as a bitmap and reading the bitmap width and height works but of course is laborious and very slow .... I've read various JPEG file format papers but retrieving the image pixel width and height seems none too obvious. Is there a logical way in VB to get this info quickly? My jpeg's are bog-standard ones made using VB's "Bmap.Save(Fname, ImageFormat.Jpeg)".
View 9 RepliesI have developed some software(vb.net) that records fees paid by the students. The purpose is that the database should be stored in a server, which can be accessed from any stations linked with it.This is working fine with a network of 10 computers. I need to publish it over the net so people could do this job logging in over internet. Database (access database) should be stored on a web based server.
View 1 RepliesThe images on my e-commerce website are watermarked with an aspx script, therefore when you are browsing products, if you want to save the image it saves it as aspx rather than jpg or png. The thing is I need to give urls of jpg for a website that advertises products. There are more than 10,000 products so I can't save all of them manually, so I made a page with jquery that get's the image part of the product display page. What this page returns is this:
<div id="result"><div id="loadpic" style="width: 160px;">
<img border="0" src="http://11.11.11.11/img/picsel.aspx?code=IPHONE-32GB-4">
</div></div>
And the output is only an image. How can I return this image not as an aspx page but as a jpg or png? Since there's a script for watermarking the image and making it aspx, shouldn't there be a reverse function?
I want to create a sort of slide show program.

Then I want it to look into another folder and grab an image file from there that will be the last image and stays up. What I want to know is how will i go about getting the program to get the random image and then how will I get it to refresh instantly?
View 2 RepliesIs there a way to read an image pixle by pixle and create a text file based in the information.Lets assume we are reading each pixle from left to right.

I already know how to call insert, update, delete & select procedures in DataSet.xsd window. And I also know how to call queries by table adapters. But I just found out that its not possible to call all functions by queries (such as insert). It works when I test the query but when I try to add it, it says "Failed to get schema for this query". So I built a few stored procedures which do many functions (such as transaction, insert, update etc...). But I am unable to use these stored procedures in VB form. I found some tutorials mentioning that it can be done by defining connections and some other stuffs with which I don't want this to be. I want to call these procedures by writing code in VB code editor window with DataSets, TableAdapters, BindingSource etc...

1. Since the plate number will be stored directly into the database after being converted from the image. However, due to the conversion process of the image into text takes few seconds, it is not able to be stored into the database... May i know is there any code that can solve it? Maybe can delay the process of storing the plate number?
2. Why during running my VB, when i click on the listbox, sometimes it will immediately pop up a dialog box to ask for video source, but sometimes not? How can i solve it?

When ever I try to add Service-based Database in Visual Basic 2010 Express Edition it just prompts me a message.

I am creating an Add-In that I want to create classes and forms based on a database structure. I can't find any information anywhere on how to programatically add code to classes. I know I can write out the files and add them to a project, but that would limit what I can do in the future. I would like the possibility to update a function in the future which would be impossible writing out a file and loading the whole thing back in. It would destroy any modifications made to the class, and since this Add-In will only be creating a framework, there will usually be modifications.
I got this line from the macro recorder:DTE.ActiveDocument.Selection.text = strDACode
But I like to keep Option Strict on, and this is late bound according to the IDE. There seems to be very little help on the IDE and how to use it creating Add-Ins. If I overlooked something please point me there, but I can find nothing. I don't know if it can be done, but I was able to do it in an Add-In for VB6.I would also like to add controls to a form, so if anyone can point me somewhere where it explains

I have created the UI elements i.e. buttons and text boxes, but am now stuck at how to implement the code.What I want to do is make the login button check what's in the username/password boxes with a table in my Access database.
View 1 RepliesI have a routine that creates a report which includes text and graphics. When I print to a PDF or printer the output looks great. When I draw the report on an image to save as a PNG, GIF, JPEG, etc. it does not look as good and I understand that is related to the 96 dpi native resolution. However, I made some modifications, and even though the graphics part of the image looks better, the text does not look as good as the PDF. I am creating the image using 300 dpi and text rendering is set at the highest quality.
