I wish to send a string held in a var to an IP address and Port number both also held in vars. I also wish to listen to a signals coming in on a particular port number so when particular strings are received I can trigger other transmissions.
View 2 RepliesI am writing a VB.NET application which needs to extract data from an XML document. The Dataset.ReadXML function would be suitable, if the XML document was held in a disk file. However I would prefer the XML document to be passed via a string property of my class object, not as a disk file.
Is there a way to make the ReadXML function take its input from a string instead of a file ? If not, are there other functions which can be made to parse XML which is held as a string.?
suppose I have variables named A1, A2, A3 ... B1, B2, B3 ... Z97, Z98, Z99. I have a certain operation I want to do using each one in turn. I CAN write a line of code for every single variable, but this will get pretty tedious. I'd prefer it if I can make a function that takes the letter and the number as arguments. So, if it gets the arguments "E" and "10" it will perform the operation on variable E10. What is the syntax for this? say a simple operation such as: result = E10 * 3 Is the syntax any different if I use constants instead of variables?
View 3 RepliesIs it possible to navigate through an array just like you can with an ado.recordset, i.e. movenext/moveprevious/etc?To give you an idea of what I'm trying to achieve. I have a form with next and previous buttons on it and I want the user to be able to go to the next/previous record in the array.
View 3 RepliesI'm starting to learn arrays, but I'm a little bit confused on how to call the data listed in them.I have the following code in a module and was wondering how I call them in my forms.I was told to use a counter to keep track of where the User is in the code in order from them to navigate correctly. I'll be using Next and Previous buttons.
Public FormList() As Form = {frmMain, frmStartup, frmUninstaller, frmAutomation}
Public CurrentForm As Integer = 0
I have a form with two web browsers. I have webbrowser1 navigate to a parent url and webrowser2 navigate to child url.
The page in webbrowser2 loads correctly but when I make a change to an element it doesn't also change the value in webbrowser1 as it should.
Should I be looking at cookies or something else?
I want to make something that can on button click navigate to a page, wait the time I specified and navigate to another page..

Well i've been trying to make something run with a lot less code(and faster) but it seems with SendKeys some things are getting lost(or discarded) by the program, its only the arrow keys as I try & make it complete a pre-defined maze to see how fast it can be completed.
If I use SendKeys("RIGHT 8") for example the maze usually only moves a few times, sometimes maybe only 1.
Also I looked up how to hold a key down/simulate it but it's not working for the arrow keys(untested on other keys).
The only way i've made it work is delays, decently delayed like 200ms & it's a huge maze but if i hold a key manually I can go much faster yet sendkeys method can't go that fast using individual presses this is why I want to simulate a holding down action.
---it must be working xample code I can make it work for my purpose if it works like on button click, etc....but I tried copying full (supposedly working) codes before & they never worked for me/my key, xample cause i've looked & tried hard(with only failing results).
MORE INFO:Also I tried SendKeys.SendWait() which is meant to wait for keystrokes to be processed & that didn't help either so my best guess is the keystrokes are processed but discarded(like a movement delay code that doesn't queue movements but rather ignores extra movements)
I would like for my program to navigate via textbox1.text with multiple lines and multiple url links inside of it. I know how to make the webbrowser1.navigate via textbox1.text with multiple lines, however I want my webbrowser to navigate to each url every 1-1.5 seconds once button1 is clicked. Yes, my webbrowser1 will navigate to the specified urls via the textbox1.text (multilines) with a button click, but I need the webbrowser1 to navigate in a order sequence from top to bottom of Textbox1.text (multiplelines) every 1 second. Here is the current code that I have to navigate via multilined textbox1.text control in order sequence:

I can't seem to get a single form that is held in a dictionary(of integer, <Form>) to create instances passed 229 times.
For instance i can only open 229 instances of the same form. I open and close the form. So technically i open 229 forms and close 228. Any forms opened afterwards give a win32 exception. I clear the the dictionary key upon form close.
I have changed the dictionary declaration to (of long) but get the same issue.
I have a little problem with my program, Boot Animation Previewer.Firstly, it loads the .zip file and extracts the boot animation in a folder called Temp. If there are existing files in the Temp folder it deletes them. But, once the boot animation is previewed, you can't select another boot animation, until you restart the application, because it gives an error, saying that the program can't delete the images, because the process is using them
View 2 RepliesI need to run an If Statement that will check a few conditions.
Basically I want to get it to check a value held in a variable "Temperature" and if the value is within "1" eaither way i.e. +-1 of the value held within the variable to then to output a text string to Label200.Text Else if the condition is not met then out put another text string to Label200.Text.
Example:
Say if Temperature value held in the variable Temperature is 8.5 the if statement checks to see if the DewPoint value is "between" +-1 of the temperature value. i.e. 7.5 to 9.5 as well as the value in Humidity is equal to or greater than 90 and Pressure is Less than or Equal to 1013.25 then the conditon is met, else the conditon is not met.
I have put some code together below in NotePad++ to see if what I am trying to do is the correct way to go about it (note I have not yet tried this code in VB.NET as I don't have it at work).
pass comment on the code and if it is wrong explain what I should do to get it to work.
Dim DewPoint as Single
Dim Temperature as Single
Dim Humidity as Single

Firstly, it loads the .zip file and extracts the boot animation in a folder called Temp. If there are existing files in the Temp folder it deletes them. But, once the boot animation is previewed, you can't select another boot animation, until you restart the application, because it gives an error, saying that the program can't delete the images, because the process is using them.
My question is: how to stop using the images? I've tried to dispose the form that loads the .zip file, but with no success.

I know how to send keys using Sendkeys.Send("{RIGHT}") I even know how to use Send keys In a timer, to repeat the key press... But it's just a key press, and it lets the key up. So If I tried to put sendkeys.send("{RIGHT}") under a Timer, then it will press/release the Right Key. I don't want that. I want to HOLD THE KEY DOWN. Here's Some Code, that I know how to do that Simulates a Mouse Click, Left Down, AND Left Up. Mouse Click. Ok...? So here's some example code of how to Send a simulated Mouse Click.

I have a number of files that are generated in a function defined as:[code]These files are immediately printed and the files are automatically saved to a directory; the files themselves are not for use by the actual software users. I timestamp the files to keep them uniquely identified for auditing purposes.I've now received a requirement to email some of these files externally to the company, and someone has complained that the current filenames are not user-friendly.So, I tried copying the generated file to a temp directory, with a friendlier name, emailing the friendlier file, then deleting it, leaving my audit trail intact, like so: [code]This throws a System.IO.IOException on the line System. IO.File. Delete (friendly FilePath) because the file is still in use, after it has been emailed.I've taken out the email code, which makes the copying and deleting work fine, so it's apparently attaching the file to the email which causes the problem.I've also tried breakpointing before the delete line, waiting five minutes, confirming the email has been sent, then advancing the code, but the same exception is still thrown.
View 3 RepliesI'm trying to make a database program in VB 2008 and have come across a problem with a query that I'm not sure how to solve. I have a combo box which contains names of teams that are held within the database, when a team name is selected I have 4 queries that will separate players (in that team) by their position, using this information I will then be able to display information about the players in a collection objects so that it can be edited and what not.
My problem is that I need to be able to refer to the records in the query so that I can assign a players details to objects on the form, I've used a piece of code to do so that I used previously to select individual records from a table, however when I click on a team in the combo box it throws up the error: "Could not format node 'ClientQuery' for execution as SQL.". Not being a particularly experienced VB programmer this error doesn't exactly mean too much to me, although I am not exactly sure of another way to tackle the problem.
The code for this query is:
Dim GK(3, 2) As String
Dim c As Integer = 0
For Each Record In GoalkeeperQuery
[CODE]...
All the fields in the query are strings. If this is not enough information I can post the query I used to select the records in the query used above or anything else that's related.

View 14 RepliesI have an array defined As string and the value stored in site is like "7E", "A1" and so on. But in order to send out this array through serial port. I need to change the the array to As Byte instead of using As String. How can I convert it?
View 8 RepliesI've been working with a sig capture application sample on a windows mobile device, The data is sent via IP to a host as a byte array and is then drawn onto the screen of the host as it appeared on the client. I was able to get this into the form of a bitmap object so I could print it or save to a jpg file. That all works well. The problem now is that I need to store this data in a database and then be able to recall it at a later time and recreate the signature image.
The byte array data is much smaller than the actual image so I would like to store it in that form. My issue is that when I convert this byte array into a string and back again my program can no longer re-create the image. Once I saw the problem I created the code below as a test and added the msgboxes to get an idea what was happened to my data.
