View 2 RepliesI'm writing some text to a memory stream and need to modify it once in the memory stream The reason I can't modify prior to adding to the memory stream is that it is from some 3rd party component. Here is an example:ms = New MemoryStreamdoc.Save(ms, SaveFormat.Html)I need to do some modification to the resulting text that ends up in ms. Is there a way to convert the contents of ms into a string, and then back into a memory stream once modified?

View 3 RepliesI wanted to ask you something which is bugging me for a while. I work an IT dept at a local bank and I got instructions to make an application which should retrieve some financial info from a financial banking stats page.
The webpage can be accessed through [URL].. and the info can be seen in the web browser but I cannot extract them because the info is not available in the source code of the page.It seems it's generating the info dynamically using a jsquery.js file.
I was wondering if it's possible to make an app which uses some cache or something (I guess the the page is saved temporary somewhere on the disk for the current session) to retrieve that data in vb.net?
1.Firstly i am using a web browser control and i wish to get the URL of the current page and write it to a text box and to a text file.
2.I would also like to read the text file back and make some sort of bookmarking menu but dont really know where to start.
3.Is it possible to shrink the text size on a webpage through the browser control some sites the text looks huge.
I'm using this code to receive messages from the server and append it to a text box:
Public Sub ReceiveMessage(ByVal ar As IAsyncResult)
Try

View 2 Repliesi have a project that requires me to make a unit converter. the units should be defined within the program. i have reached a point where i save the defined units in a text file for a simple example converting meters to kilometers where it gets divided by 1000 i made the program to save the a string in a text file to represent that as:
meter,kilometer,0.001
which means it gets multiplied by 0.001 anyway the problem that i'm facing that when i want so save another units in the same file the previous units gets deleted. how to make the program update the text file that it adds the new defined units in the same file but before that it looks in the test file if the unit is already exists and if it does it will replace it with the new value
is it possible to read a string just before the second comer? foe example if the string in a file is: meter,kilometer,0.001 it will read it as: meter,kilometer and is it possible just to read the last value? 0.001

I found one solution that , if change user rights manually then this problem solved.Follow these step to change your account settings.Control Panel-->User Accounts and Family Safety-->User Accounts-->Change User Account Control settings-->Never notify(Set tab to never notify).After this change need to restart system.Now can make all changes like windows XP into Windows 7.can also make changes into program files.
Its working fine, but need to make these changes manually in OS.but its not efficent solution. So if any one knows how can make these changes by coding that will nice.

View 3 RepliesI have a problem with form instantiation. This is what I want to achieve: I want to create forms with a toolstrip attached to them right from the moment these forms are instantiated. I have several ideas:
1. making custom Form Control
2. modifying the new method for forms
I'd like to focus on idea 2. I want to know if there's a way to alter the in-built New() method, so whenever the compiler instantiates a form, somehow when the constructor(New method) of each form is invoked, the compiler adds a toolstrip to the form.

View 1 RepliesI have a project, let's call it myproject and it's in the folder, myproject (VB2008>projects>myproject)
I want to eventually open this project and make some changes to it and the end result is that I will have a new piece of software.
So, here's what I do I copy the folder myproject to the desktop, rename it projectb and put back in the projects directory. (VB2008>projects>projectb)
Now, I can make any changes I want to the program and save to the projectb folder, BUT all of the entities (form, design view,settings etc) will still have the original name of myproject.* (and there's nothing you can do about it?) Is this the case? I don't see how you change the name of the "individual parts".
