hey been looking around for an example of Sendmessege to send keys, but all you find is the basic notepad example, can anyone please show me the way to use Sendmessege to sendkeystrokes to any application (i have the hwnd)
View 3 RepliesSo I've been doing a lot of reading today and apparently SendKeys isn't very reliable anymore.Does anyone know of another alternative to it for what I need:
The application works by the form being positioned over a open window, notepad, word, excel etc and it then determines what it is over, notepad, word, excel etc and then reads the file, and does some processing using SendKeys at the moment.Though I do believe I could probably change the later at some point. The problem I'm having right now is when I try to send the Alt + Tab to change focus it's working roughly 12% of the time.If you are wondering I ran it 50 times and it worked 6 of those,thus the 12%.I'm thinking that is rather unacceptable.This is what I'm using which should work: SendKeys.SendWait("%{TAB}")
XP Service Pack 3 and vb.net 2005
First off, using VB2010. I'm in the process of upgrading some applications from VB6 to 2010 and haveing a great time of it. The current application I'm working on is using Sendkeys of which I have changed over to the WSH.Sendkeys of which is pretty decent. Basically the program is copy and pasting the current open file, reading some data and saving it as a different file type. It also has to change xls files to csv and then saving it to the format as well as a smiliar thing with word. Thus the reason for the copy and paste as it's changing the extension to a dot date (for example, test.830).This is the flow of how it works for a text file (most basic)
1. changes focus to notepad
2. Select all Copy to ClipBoard
3. Open Programmers File Editor and a blank file
4. Paste in text
5. Save as code.date extension to the directory
Excel files obviously have a few extra steps.
At the moment I have this to change focus of an element:
SendKeys.Send("{TAB}")
Instead of using that I was wondering if I could do something like this:
WebBrowser1.Document.All("id").InvokeMember("click")
But to get focus to the next element in line, like the next one from the current focused item.
What is the difference between SendKeys.SendWait and SendKeys.Send?Send obviously will just send they key immediately, but does SendWait actually wait for the message to be processed or does it also send it immediately?The function's name itself is just confusing. Which one should I use if I want to send keystrokes to a 3rd party app immediately, or is there no difference? To me, a few milliseconds is a big difference.
View 3 RepliesPrivate Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
CheckBox1.Checked = True
While CheckBox1.Checked = True
SendKeys("{END}")
End While
End Sub
That is the code, the error is "SendKeys is a type and cannot be used as an expression."
I'm looking for the underlying Win32 API call that the DotNET Framework invokes on a SendKeys.Send or .SendWait call, or a Win32 API Equivalent to SendKeys. I've already experimented with SetKeyboardState which seems like the way to go, except that it does not raise any kind of keyboard event that causes the set keystates to register with an active application or the OS (at least not until another key is pressed; for example I can meddle with the keyboardstate before events process on a natural keystroke, but I can't invoke a keystroke programmatically).
View 1 RepliesIm currently developing an app, in which there is a list box which will contain between 200 and 3000 items. These items are loaded into the list box from a .txt file. Now on the same form i have Picture boxes x 6 Textboxes x 5..The contents of which changes with each list item selected, and to do this i have the code attached to the list box, heres a snippet of the [code] but at the moment with 178 items on the list the total code is pretty big, and i get the feeling it would run faster if loaded dynamically.Am i right in thinking that? Especially when the list has 3000 items, thats alot of code to have attached to a listbox.And how do i go about making the code dynamic, im looking round the forum and seeing ADO database mentioned alot and that seems to be the answer at least for the text fields, would that also work for the picture box fields?
View 1 RepliesI'm writing an app that reads zip files from a folder and then displays them in a listbox. As a user clicks on one of the zip files in the list they can see a particular file that is located inside the zip archive in a textbox. The way I'm doing this now is to read the files from the folder and store the zip file name and the file associated with it into a two dimensional array. Kind of like this:
Dim a_files(500, 1) a_files(0,0) = name of zip file in folder a_files(0,1) = name of a particular file in the zip file The problem is that there may be more than 500 files so the array has to be scalable. I know you can use 'ReDim Preserve' to resize the right element on the fly, but I need to resize the left element. I've looked at collections, but I can't see an example where they can be multidimensional. Does someone know of an alternative way to store these values that would have the flexibility I need?
On our intranet website, I need to give option to user to specify the location where they would like to save files. The files would be generated by a background process. Is there a way user can specify the location? I can not use FileUpload since that requires file to be specified. I notice that FolderBrowserDialog is for clientserver vb.net app and not asp.net.
View 2 RepliesI have a vb application ive been working on and its pretty much complete. I posted in the asp section but we couldn't get it figured out there so im reverting back to vb so looking for some help.I have a vb.net app I created and I have an internet browser embedded in it calling an asp page. the asp page is just a simple file that searches an access database. I used the asp page because I wanted to display the results with graphics and tables so I used html for that.Everything technically works except I am running it on a local intranet and the asp file is located on a server that is REALLY slow so it is taking 20-30 seconds to get my results. so, my question is, Are there any other options or ways I can do the search within the vb app itself so everything stays local and I don't have any speed issues. I can't install IIS on the local computer because the IT department is strict unfortunately.I don't HAVE to use "html" but I would like it to look nice with graphics and html was the only way I knew how to do that.
View 6 RepliesWell this listbox contains sensitive data not very important but i dont want the end user to be able to see what the listbox contains, therefore i have hidden the listbox But my question is how do i store this information i could easily write it to a text file i know but the user could locate the text file. So i attempted to create my text file as a resource and that failed as i can read from it i cant write to it. More simplistic question. I have data i need to save from a listbox but if i save it as a text file the user could still access it and i dont want the user to be able to acesss the file i would like it to be internal because i also dont want the user to be able to delete the file?

View 5 RepliesI've made an alternative to the MdiWindowListItem for window navigation in an MDI application. It consists of each window being added as a toolstripbutton to a toolbar, similarly to the Windows taskbar. I don't use any of the mechanics I should probably use, such as for loops catching each child window etc etc. Instead I look at window titles and do a lot of string manipulation and using counters etc.
I'd like to get rid of my method and use something a little more technical. I'd like to have the same effect, but to be able to add toolbar buttons relative to the MDI children as opposed to looking at window titles and such, because I've also got a plugin system that allows users to create their own windows and add them as mdi children. But, if a plugin is added, it doesn't get added to my toolbar taskbar thing because the titles are all user defined and I cannot control them.
So, basically, I want something exactly like the menubar's MdiWindowListItem feature, but using my toolbar idea. I want all MDI children to show up in it, including the 3rd party windows.

I am trying to create a Macro for another program.I want to periodically send keys to the program, the keys are F1-F4.The program I am sending it to has different names from time to time.

I was hoping you would be able to help me out. I want to automate a process on a website, through my program.I want to do sendkeys to a web browser component, and also be able to focus on links and click them.Here is what I want:the browser is by default on page 1.there are a bunch of links on page 1, but i want the program to automatically click the link with inner html that says "Link 3". Next, i want the program to wait for the next page to load, then find another link. Finally, I want the program to focus in on a textbox, type some data, then click a submit button, which takes the browser back to page 1. I want this process to keep looping over and over again. Can anybody help me with the functions involved in waiting for a page to load then finding a link based on its html?

View 6 RepliesVB 2008 Express. I write a program designed for interacting with an Android phone that is hooked up to a Windows machine. One of the tools in my program is a utility designed to assist the user root their phone. Now in order to root it goes through a command line utility called adb which lets you access a terminal on the phone. It must then type commands in that terminal. Most processes that this program does can be done through a batch file, however rooting the phone isn't one of them. The reason being once it actually logs in to the phone's shell, it stops running commands because it just gets stuck on that line, waiting for it to finish.
So despite being a little primitive I designed that part of my application to use sendkeys. So the way it should work is:
1) It launches powershell as an administrator
2) Types the following commands (I have abbreviated the number of commands it types for the sake of this board. There's actually about 20 lines total):
SendKeys.SendWait("mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system{ENTER}")
SendKeys.SendWait("cat /system/bin/sh > /system/bin/su{ENTER}")
SendKeys.SendWait("chmod 4755 /system/bin/su{ENTER}")
SendKeys.SendWait("flash_image recovery /sdcard/recovery-RA-heroc-v1.2.3.img{ENTER}")
Now it seems that for 90% of users, this works perfectly fine. However for a small group of people, this is what actually gets typed in to the powershell window:
> /system/bin/su{ENTER}
_image recovery /sdcard/recovery-RA-heroc-v1.2.3.img{ENTER}
For the people that have this happen to them, it's always the exact same thing. It's like it completely skips all letters until it gets to a special character. I have no clue what could be causing this. The only thing I have found was that sendkeys wasn't totally supported but that running it as administrator would fix that, which is why I now have it run as admin. But that didn't work. I also had some success by using powershell instead of cmd, but it's still failing for a small number of people.
Every other part of the program works perfect except for this. I haven't found any common element between the people that it is failing on. They aren't running the same anti-virus or the same programs. I program and debug on Windows 7 64 bit, yet someone else can run it on the same OS and it won't type it out properly. Is there something better that I could be using instead of sendkeys?

I was just wondering if there was a way to send the button value of a button on a controller to the controller. What I mean is, if the xbox 360 controller was a windows form, clicking the mouse on one of the buttons would be like regular button presses, and then the button.performclick for that button would also press that button. Does anyone know of a way to do this?
