I based a lot of my project on your Codebank submission for navigating web pages. I have ran into the problem a few times where it would stop navigating. You had recommended deleting the Interop files and rebuilding the solution. I have done this and it used to work just great afterwards (I was deleting all Interops and AxInterops in the Bin/Debug and Obj folders)I now have a strange case where it compiles and builds and navigates as expected on the computer I coded it on, but when I install it on another machine, it fails to navigate again. I made certain it worked directly before building and that I used the correct setup file but nothing I seem to do now cna make it navigate on the second machine. What else should I check?
I downloaded the extended webbrowser control created by Matt Kleinwaks (thank you for sharing that).I am using the control to fill out forms on a website. The website uses a popup that contains an html form. The popup form will not close if I click the the html submit button or the close button (it does when using a regular browser). The bigger problem I am having is that when the popup reopens, it contains data in the html boxes that was I have already submited on a previous iteration of the popup. Like it is being cached or something. I am wondering if this has to do with the html buttons not working properly.I basically hit submit on the form, the browse rcontrol hangs up, then I close the form manually. Is there a line of code or something I can add to get it to work right? Like clearing a cookie or disposing of the popup form after I close it?
I am on my way to create my own tabbed advanced webbrowser in vb 2008.I have collected most of the tools for that,but i have the following problem:
The webbrowser control in vb 2008 is an instanse of IE.But i want to build my 'own' webbrowser, with custom contextmenustrip, navigate error messages ,etc
Encryption would work fine, so long as it is symmetrical and done prior to storing the info in the setting, and decrypted after reading the setting back in.
The key or iv for the encryption (which is a series of bytes) could be generated from a user defined password, making it so the key used to decrypt is never stored even in the compiled application. Only providing the main password would provide the key to decrypt the data, limiting the attack surface to pretty much just brute force dictionary attacks.
I think that is probably a bit beyond the scope of this question though, he probably needs to start just saving and recalling data properly.
How would one go about doing this? I've read a little about encryption and I even have a demo program, I just don't understand the overall process of this. (I included the OP in the topic's title because it was his idea, and he might be able to explain it the best).
I am trying to automate a web page via the weBrowser and the button that i'm trying to click has no ID only a value. here's the html code for it: "<button class="buttonf" onclick="window.location='staticpage.php?accept=123456' ">Accept</button>"
I can't useGetElementById as the button has no ID. If I do
HtmlElement goButton = this.webBrowser1.Document.All["Accept"];goButton.InvokeMember("click"); My script stops showing a nullreference error highlighting the "goButton.InvokeMember("click");"
[Code]....
My script give me an "Sequence contains no matching element" error at the "HtmlElement submitButton" line and sometimes the page has more than one of these Accept buttons, so I would need to be able to tell the difference between each one as well or at least be able to click on one without the script breaking
In the process of upgrading one of our applications, it was decided that the users needed an image viewer. We already have a browser based application that does a great job at that task. Since a lot of time and effort was put into the browser based code, I really want to use our browser based viewer rather than write new code to do the same.So, I've added a WebBrowser control to a form and figured I will call our Java applet from there and not re-invent the wheel.
How I can execute a stored procedure and the put the results into a webbrowser to display. I know html so I will format the stuff to look how I want it to.
I use new WEBBrowser control (VS2005) in my program (WinForm) for open web site. (VB2005)After using method "navigate", in my webbrowser control I have HTML page from some website.This HTML page has some input button with events or input text control or other interactive control on it. I can click with mouse on that buttons or input text from keyboard or select value from combo box to send this page back. question:How I can execute this from my program code, using property and methods WebBrowser control?
I've seen extended .NET method libraries such as this and this.In VB.NET, since you create your extended methods in a Module, How do I make them into a DLL?? (like in those links above) Its not possible to build and get the DLL from a Module.
I created a couple of extended methods in a VB.NET module. I put them inside a Class, built it and got the DLL. From another program I made a reference to that DLL and imported it using Imports as well.The extended methods appear in IntelliSense and it works but a warning appears in the Error console saying,Could not resolve this reference. Could not locate the assembly "nK0deExtendedMethods". Check to make sure the assembly exists on disk. why this error occurs even though I have referenced the DLL?
This is the Class where I've put my module with the extended method.
In my current project everyone names variables and methods after what they are and what they do. This is good for quickly understanding the code, but with a lot of long varible names comes some headaches, such as when copying a dataset to an entity/object. So, while you understand the code, the readability still takes a blow.
veryLongVariableName.Id = datasetVeryLongVariableName.Id veryLongVariablename.Something = datasetVeryLongVariableName.Something etc.
Using VB.NET's With keyword can help.
With veryLongVariableName .Id = datasetVeryLongVariableName.Id .Something = datasetVeryLongVariableName.Something End With
Now, my question, is there any way of using With, or something similar, but for several variables at the same time? Something like:
With veryLongVariableName As a, datasetVeryLongVariableName as b a.Id = b.Id a.Something = b.Something End With
I'm all for descriptive naming conventions, but they do tend to clutter things. Especially in VB!
I made a simple extension of the PictureBox control. In retrospect, this might not have been the best starting point, but that's currently irrelevant. This is the first time I have tried extending a picturebox control. The point of the exercise was to attempt something odd, but I haven't even gotten that far. The control shows up in the common controls panel, and I can drag it onto the form, but it doesn't get added.
What am I doing wrong? There is very little code behind the new control at the moment, as I am just trying to test a concept, and what code there is doesn't actually get run because the control is never created, so NO code gets run.
I need the option to choose margins (PageSetupDialog), preview the document PrintpreviewDialog) and to select the printer (PrintDialog) before actual printing from extended RichTextBox.
I have used extended RTB control from MSDN site Getting WYSIWYG Print... : VB.Net Public Class myRichTextBoxEx
I am currently writing a program with Visual Basic 2005 to talk back and forth to an external machine over UDP/IP. I recently had some trouble with it which I got help for today. I need to send the information to the machine using ASCII. I had it figured out so I could send HEX numbers 20 through 7F to the machine. The problem I had and got help for was writing the HEX numbers 0-19 to the machine. The help I recieved said that instead of writing the actual HEX number into the machine, "70" for example, I should write Chr(112). This allowed me to send numbers like HEX 01 by simply writing Chr(1).
My new problem is that I need to write the HEX numbers 90, 91, 96, and 97 to the machine. Every time I try and send these numbers my computer sends out a weird number. For example, I try to send HEX 90 as Chr(144) and it ends up coming up as HEX 3F on the opposite end. After looking up the ASCII table online I found that Chr(144) is an Extended ASCII code.
I've been reading up on this whole subject, but I never came across this specific problem. I already understand that the whole idea of serializing an entire form is a horrible idea and just doesn't work. But, I am encountering a bit of a different problem. I have a class that inherits the "button" form object, that I call DataButton.
Now for my problem. I want to be able to serialize this class, but I don't need any of the information from the actual button class. Is there any way to bypass the fact that I can't set the button form object to Serializable() and notify VB that when serialization is to occur, it should simply skip over that information? Theoretically, if such a procedure were possible, I'd be able to do the entire serialization without a hitch.
I came up with the idea earlier of removing the "inherits" feature from the class, and having simply a button within the class, but that makes my program really difficult to work with as I am constantly changing the location, size, backgroundImage, text, and whatnot. Thus, immediate updates would be much tougher to work with.
I have created a little demo application which is able to create a meeting request by using the Exchange WebService (EWS). I would also like to add some custom properties to this item but up to now I have only found examples which use the Exchange Managed API, which I won't use. There must be a way to create these properties by only using EWS... Does anybody know how and can provide a little code example?
I'm Alan and I'm writing a little program (beginner), but I'm stuck and I can't get any further. So I hope one of you guys can help me solve following problem.Let me explain what I'm making, so it can give you all a better perspective.
For a this project I'm receiving data via the RS232 communication port. So basically I receive bytes. These bytes are converted to a string. So for example I receive this:"BAA" this is good because I can get the correct decimal value for "B"(66) and "A"(65) using the command asc("A") in .NET.but sometimes I receive a character that exceeds the 0-127 limit for example ""(128) (please see [URL]..But now when I try to get the decimal value of "" I get 63 instead of 128. I searched the Internet and forums for an answer but I didn't find one that fits my problem.
So if it's possible, can one of you code experts explain me how to fix this problem ? It would help me a lot. I hope I described my problem clearly, but if there are some questions,
I am trying to locate the runtime install for Visual Basic 6 Runtime Extended Files. I am not a developer just the guy truing to get it onto the systems for them. My question is simple anI hope the answer is the same. We are converting our systemsfrom Windows XP to Windows 7 and we need the extended runtime modules so a number of our applications will actually work.
I cannot locate the install for this in the Visual Studio download area. Is the re-distributable part of the studio install (so it should be on one of the developers systems) or do I download it from somewhere else.
I want to explicitly inform my user that they are not allowed to use any characters from the extended ascii character set (128-255). When I try to create a string of these values using the following [Code] It outputs them fine, with the exception of a bunch of blanks in certain areas(I am assuming these characters are unprintable), but I noticed that when I hover over the value of sVal in the VS, the tooltip/quickview of the value is written nicely on one line. Any ideas how to remove characters that would appear to be blank spaces (unprintable) when outputting this list?
