View 4 RepliesAutomate Entering Information Onto A Printer Web Interface?
Feb 24, 2011im trying to automate entering information onto a printer web interface. I was sucessfully in creating a problem for one particular model printer but not another(differnet manufactor).
HTML button code:
<input type="button" class="w10pt" style="width:136px;display:block;font-weight:700;" value="Login" onclick="location.href='/start/login.htm?arg1=1'">
I tried:
theElementCollection = WebBrowser1.Document.GetElementsByTagName("input")
For Each curElement As HtmlElement In theElementCollection
If curElement.GetAttribute("value").Equals("Login") Then[code].....
it doesnt work .I read this in another post:
"There are several possible approaches; you can try to identify something other than the id, such as the element's name, class, tag name, etc. Another approach is to identify a nearby element, whether it's a sibling, child, parent, etc. that is easily identified (it has an id, or is in some other way unique) and get to the element that you want relative to the element you know you can find. For example, maybe the element is the only child of a </div> tag or a </span> tag that does have an id." So this is the parent to that code:
<div align="center" style="padding:5px;border-style:solid;background:#ccc;border-color: #000;border-width:1px 1px 0px 1px;"><input type="button" class="w10pt" style="width:136px;display:block;font-weight:700;" value="Login" onclick="location.href='/start/login.htm?arg1=1'"></div>[code].....
The site has other buttons that i need to click, so if i can figure this one hopefully i will be able to get the other ones.

Printer Stuff - Detect If My Printer Is Busy ?
Mar 18, 20111. Detect if my printer is busy, because my code tells the printer to print more pages that it can cope with, so I need to delay the command for 'Print the next page' until the printer has finished printing the previous one.
2. Shift the output to my printer so that it gets printed in it's entirety on the paper, instead of seemingly being anchored to some nebulous point on the A4 page. It starts printing at X = 29mm from the left edge, and Y is 28mm from the top, and stops at X = 22mm from the right edge and Y stops at 22mm from the bottom edge, leaving (aprox) 50mm of X and 50mm of Y unprinted.
3. Get useful information on Bounds, which I'm fairly certain is what I need to control where my printing should start and finish.
I've hunted through this forum, MSDN, 'Help' (a misnomer if ever there was one) the VB Library and one or two other forums, which either baffle me with reams of code or suggest code to try which either just don't work or which doesn't declare all the variables and usually don't suggest what type of variable I need, it's all very frustrating

Method Which Check If A Certain DSN Exists Then If It Does Extract Information And Use Information For Connection Purposes
Feb 2, 2011I was looking for some stuff online, and i was looking through my reference sheets for vb.net, but it seems in the code i have found, there is declare in methods. Below is an example i am talking about. The thing is, that i dont recognize it and believe that it is an earlier version of Visual Basic ( 6 or earlier) which used it. Should i just keep looking for different code?
Public Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal _
lpSubKey As String, phkResult As Long) As Long
Goal: Find information on how to implement a method which will check if a certain DSN exists, and then if it does, extract the information and use the information for connection purposes.

C# - Internal Relationship Between Properties?
Jul 21, 2011My issue involves relationships and cascaded effects between properties, and I'm wondering what best practices are on this.I have a class that contains a list of varying length of numbers. When editing the list, sometimes the user prefer to set a TargetSum, so that the program enforces the list will always add to this sum. I am accomplishing this by programmatically setting the final element in the list such that list sum = TargetSum. For example, if the user chooses to UseTargetSum, then sets TargetSum = 10, then creates a list of length 4, and enters 1, 4, 2 for the first 3 elements, then the final element is programmatically fixed to 3. The user cannot change the final element themselves.
I do this behind the scenes by handling all necessary events, such as a list element value change, list length change, and the UseTargetSum option change. For each event trigger, it recalculates the last element's value.It works but then there was a bug when loading saved data. If a list is loaded by sequentially adding the elements, the handlers modify each entry. Regarding the example, when the first value of 1 is entered, the handlers say "a value was just added, the sum should be 10, there is currently only one element, so it needs to be 10". So the first element gets changed to 10 behind the scenes. When the second element is next added, the handlers say "a value of 4 was just added, but the first element is already 10, so it should be zero." At the end of the load, the final list reads 10,0,0,0 instead of 1,4,2,3.
I know it is possible to rearrange the load procedure such that I get the correct list. For instance, I could avoid enabling the TargetSum event handlers until after all the data is loaded. The list would first be created as 1,4,2,3 and then the handlers would change nothing.
But this experience makes me wonder if I am opening the door for other sneaky side effects. It seems you should be able to load data without worrying too much about an implicit ordering. It also seems unusual to have "cascading" effects between class properties. Is there a more accepted approach?
The other alternative I'm considering is to only enforce TargetSum only inside UI forms. Ie, when you know it's a user making the change, then enforce the TargetSum, but otherwise leave the core class logic alone.That way database loads, etc, are left unaffected. But I guess the downside of not having ubiquitous enforcement is that opens the door of incorrect sums via some unforeseen complication.
Internal Bit-by-bit Decimal Format
Apr 7, 2012I'm using Visual Basic .Net 2010 Express.I know, for example, that the Visual Basic ( IEEE 754 ) Internal bit-by-bit Double Format is: Bit 63 = Sign, Bits 62-52 = 11-bit Exponent, and Bits 51-0 = 52-bit Fractional Significand.But, I can't seem to find any documentation on the Internal bit-by-bit Decimal Format.There also don't seem to be any workable mechanisms for accessing the bit structure or copying the bits to another Format for internal processing and returning the result to the Decimal Format.[code]to separate the ULongVariable into bytes for convenient manipulation. A similar reverse process allows moving the manipulated bits back into the Signed Long Variable.But, methods like << and >> are not extendable to Decimals per the Microsoft Documentation ( and I tried them anyway, and confirmed that they don't work ). Nor does there appear to be any way to copy the 128-bit Decimal into two 64-bit Unsigned Long Variables, or vice-versa.
I could, of course, forgo the use of Decimals and define my own MDJDecimal consisting of two ULongs, but that seems a bit of an overkill, and its methods would likely incur significant development time, and would probably also be rather excessively slow and cumbersome.I know I could write a workable routine in Visual C++ .Net using the Unmanaged Native Assembler, but I don't know enough about how to integrate that with Visual Basic .Net code, and I don't want to irrevocably tie what I'm developing to the Intel platform.I might also be able to write it in Managed Visual C++ .Net, but, again, I don't know enough about how to integrate that with Visual Basic .Net.
Internal Margins On TextBoxes

View 1 RepliesBack With A Small Project For Internal Use?
Jun 3, 2011Its been a very long time since I don't show up here.Now I am back with a small project for internal use, but I need a little help.I want to make a program that allows me to change file attributes, like 'hidden', 'read-only' and 'system'.It seems pretty simple, but I want that multiple files can be modified at once. For this I would need a list that shows the files into the interface. There is what I can't get.
I first thought on a listbox, but there is also a listview which seems much more complete, but I just don't know how to use it. I was wondering if I could make something like: I open a folder, all the items inside that folder would be listed inside the listview.I learned a bit, but not enough. I've set the listview to 'details' mode, so I can actually list items. Also, I've added three collums: one for file name, other for file size and another for file attributes. I just need to learn now how they works.
Check Internal And External Duplicates?

I have gone through lot of logics..some of which are ...
- Common and currently testing out..
- First insert the excel sheet data into DB..then query by following
select distinct id,mobilenumber from scrubmaster where calltablename=<calltablename given by the uploader>
Then loop for duplicates...
