Use Asc() Function To Find Result ?
Sep 22, 2011I have a problem with Asc() function as a blow picture,I will explain each step as I do.First I convert some values to ASCII code and store in value variable, then retrieve 3rd position of variable (4th line of the picture.)
and use Asc() function to find result which it show 63. (like 5th and 6th line).But I try to manually use Chr() function, the result become 2nd and 3rd line.So for the Asc("ˆ") func. result should be 63 or 136?

View 4 RepliesSetting A Variable To Accept The Result Of A Function By Calling The Function With Many Parameters
Feb 17, 2011I'm currently working with a client's VB.Net code, which was developed for them by a small development shop a few years ago and which they purchased and have been maintaining and uprgrading since. This client's primary developer is out on indefinite (likely permanent) medical leave and I'm now filling in until they bring in a full timer (as I'm a contractor here). My current task is to add some functionality to a the VB.Net code they purchased. I'm finding practices and techniques in the code that absolutely baffle me and can't make the code do what I want. I'm starting to wonder if it's me and was hoping to get some thoughts on the code I've encountered.
For example: Setting a variable to accept the result of a function by calling the function with many parameters, clearing the parameters in the function, setting them to some value, calling another function with those new values, then never using the values returned by the functions. I'll add a code snippet in the first comment since this is already getting long.
Find The Handle Of The Child Window For The Yes Button In The User Account Control Window?
Mar 20, 2010I am trying to find the handle of the child window for the Yes button in the User Account Control window so i can click it. This window has a structure with a few child windows with the same name.
Dim hwnd As IntPtr = FindWindow(Nothing, "User Account Control")
Dim hwnd2 As IntPtr = FindWindowEx(hwnd, 0, "DirectUIHWND", vbNullString)
Dim hwnd3 As IntPtr = FindWindowEx(hwnd2, 0, "CtrlNotifySink", vbNullString)
Dim hwnd4 As IntPtr = FindWindowEx(hwnd3, 0, "Button", "&Yes")
There are multiple CtrNotifySink with its own Button child window or other child windows. How do i search thru the different CtrNotifySink window to find the one that contain the Yes button so i can send a click to it? I do need to find it before i can send a click, right? because i try just sending it to the main window with sendmessage and nothing happen.I even try sending it directly to the handle found by spy++ of the yes button with bm click but nothing happen?
Use Window Like A Function / Pass In Parameters / Use Window / Get Data Out When It Closes?
Dec 13, 2011I am creating a window that is a generic keypad for editing numerical values on a touchscreen. I would like to press an 'edit' button to create a copy of the keypad window/bring up a reusable version of the same window (I don't care), but pass in parameters: the old value I'm manipulating, and a title to be displayed above the number pad. I would like the user to be able to type in the new value, then press the 'done' key to submit this value and have it sent back to the main application window into my custom control that contains a text box.(I have the number pad's layout sorted out already; I'm already using a variation on it to set a global password 'access level'. It's getting the information in and out that has me scratching my head.) [code]

ASP Function That Returns Result From Stored Procedures
Apr 15, 2010I am working on a project that requires me to hop into to separate DB's. So I have figured that I need to have multiple functions inside of my VB page. The only problem I am having,is I am not to sure how to get this all accomplished. So far I have figured out the overall structure, just need to implement that structure.
Here is my idea:
The main Function would call two other functions. We can Call them Sub Function 1 and Sub Function 2. So, the main Function takes the saved sessions information for the E-mail address and dumps in into Sub Function 1. It needs to open up a new connection to the db/stored procedure and RUN the following procedure and then return the result. Here is the stored procedure and what I think is correct.
CREATE PROCEDURE WEB_User
(@EMAIL_ADDRESS varchar(80) = [EMAIL_ADDRESS])
AS SELECT MEMBER_NUMBER
FROM WEB_LOGIN
WHERE EMAIL_ADDRESS = @EMAIL_ADDRESS
So my question is, what is the function suppose to look like? how do I send the session information to the procedure? and finally, how do I return the stored procedure results and push back into the main function so it can be carried into sub function 2?
Asp.net - Function Chaining Depending On Boolean Result
Jun 7, 2010This is just an efficiency question really.. I'm interested to know if there is a more efficient or logical way that people use to handle this sort of scenario.
In my asp.net application I am running a script to generate a new project my code at the top level looks like this:
Dim ok As Boolean = True
ok = createFolderStructure()
If ok Then ok = createMDB()
[Code]....
I create a boolean and each function returns a boolean result, the next function in this chain will only run if the previous one was successful. I do this because an asp.net application will continue to run through the page life cycle unless there is an unhandled exception and I don't want my whole application to be screwed up if something in the chain goes wrong (there is a lot of copying and deleting of files etc.. in this example).
Implement The .Find Method When Binding A BindingSource To LINQ (IEnumerable) Result?
Mar 15, 2008I'm binding a DataGridView to a BindingSource to a LINQ IEnumerable, I found that the BindingSource.Find method throws an exception because .Find isn't implemented in IEnumerable (and the BindingSource just passes the call to it's DataSource). I need to use BindingSource.Find to select/highlight a particular row in the DataGridView.
Is there a feasable way to extend my DataContext to support this behavior w/o breaking anything else? I expected to find the code out there already, but I've searched exaustively with no luck.Without it, I cannot "move" the BindingSource using .Position and that's a pretty common use of the BindingSource I think.
C# - Hash Function To Obtain Limited Length Result
Apr 18, 2012I need to hash a number (about 22 digits) and the result length must be less than 12 characters. It can be a number or a mix of characters, and must be unique. (The number entered will be unique too). For example, if the number entered is 000000000000000000001, the result should be something like 2s5As5A62s. I looked at the typical, like MD5, SHA-1, etc., but they give high length results.

View 2 RepliesFunction Overloading Add Result Type To Parameter Signature?
Dec 7, 2009Can someone on the VB language team explain why a function result type is not part of the parameter signature?If it were then function overloads would also work for functions that only differ by the result type. In some cases, this is useful (aka cleaner code) especially when you have strongly typed data.
Other languages have this and implement it by considering the function result as an OUT parameter either as param 0 or at the end of the param list (stack) so existing type matching verification can be performed by the compiler.
In VB, the workaround is just messy and would be easily fixed by a language change. This example is overly simplified and not meant as a solid justification for the request Say you have a parse requiirement that takes a comma delimited string in the form: "31,32,33,34" or "bob,carol,ted,alice"

Passing The Result Of An Array-Valued Function From A Fortran95?
May 25, 2011I am interested in developing a multi-language program that will have a main .NET GUI but will perform calculations by calling procedures from a Fortran95 dynamic link library file. Right now I am just playing around with a very simple project in order to get the interoperability between the .NET framework and a Fortran95 (*.dll) file working correctly. So far, I've been able to pass the Fortran95 (*.dll) file an array from VB, sum all the elements of the array using an intrinsic Fortran function, and pass the scalar result back to the .NET framework with no problem. However, if I try passing Fortran the exact same array, construct the transpose of that array using another intrinsic Fortran function, and try passing the transposed array back to the .NET framework I keep throwing an exception. I am not a programming wiz, but it appears that when Fortran stores an array in memory, the .NET framework doesn't know how to read that. I am looking for some guidance on how to pass an array from the Fortran95 (*.dll) file back to the .NET framework.

Find Function Does Not Find Last Occurrence
Dec 12, 2009I have a rich text box with the following text in it:
word word
I am finding the endings of the word, that is, the string "rd". The following code finds the first occurance, but then fails to find the last occurance, and the variable "indexToText " changes to -1.After the first search, the debugger shows the startLocation at character position 4, so it is not past the second occurance but still will not find it.
indexToText = FrmMain.RichTextBoxPrintCtrl1.Find(searchValue, _
startLocation, eof, RichTextBoxFinds.None)
If I change the text to:
word word word
It then finds the first two occurrences and fails to find the last occurrence.No matter how many words I add, it always fails to find the last occurrence.
Setup A Function Involving Multiplying A Cell By A Set Number And Then Having The Result Round To The Nearest 10?

Process And Find A Window?
Jun 17, 2010what I am trying to do its to automate a user interraction by code.First I have a button named "start" once pushed I navigate with webbrowser to download a file. What I try to do it is to find the window "File download" by his title name, I allready made a seperate thread to loop into to list of process until it found the window "File download"
Where I need help, it is with the process list. I try that code below but I don't see the process "File download" in the list.and once I found it I would like to use sendMessage() api to simulate the click of save.I would like to find another window after to catch the window "save as" and click save and if the window that ask for overwriting appear I would like to find it too and click yes.
Why I use webbrowser instead of httpwebrequest it is because the web site required to login, i try using cookie, etc. No success so I decided to use webbrowser, I navigate first into the login page, I login manually and once it is done I can click the button to start downloading. I want to make an automatic download loop, I have lot of files to download on that site, sometimes .doc and other times it is .pdf
I didn't found a way yet how to force webbrowser to ask for downloading .pdf instead of opening it in acrobat, if someone can help me for that point too
