FindWindow - Increase The Number Of Vendors To 10, The Programme Failed?
May 13, 2011
I am using VB Express 2008, on Windows XP Pro. I have written a programme which tests another programme which compares prices and terms from several vendors. This Bid Tabulation programme, compares prices and terms of up to 10 Bidders and 500 line items in mixed currencies.The testing programme, initially, would not work and I discovered that I needed to introduce a delay in order for it to run the Bid Tabulation programme. So my initial code, using the delay, was:
[code]...
And the button was clicked, and the Bid Tabulation programme started and ran successfully, as long as the number of vendors was 5 and the number of line items was 5. when I tried to increase the number of vendors to 10, the programme failed.I then discovered that at the point of failure, when the particular ParentHWND=0, if I introduced:
[code]...
Does anyone know what I am doing wrong, or whether there is another way to assure that ParentHWND will not equal zero without using a time delay?
I saw lots of things online that look like you can't create a number that increments with every build automatically - rather you have to set it in AssemblyInfo.vb - is that really the case??
I`m make program for order form, I use order form code with name MR/IR/001, when I start Program It`s fine but when the order form code get MR/IR/999, It`s Stuck and won`t get increase the number, I want it the order form code go to MR/IR/1000, MR/IR/1001, MR/IR/1002 until 5000 how to get code work,
THIS THE CODE USING VB 2008 and database using MS access 2007
Dim strTemp As String = "" Dim strValue As String = "" Dim sql As String
I'm trying to code an 'increase' button to prompt a user to input a rate by which to increase select prices in an array.It should request the increased rate, then request a number from one to five, representing which price in the array to increase.Then, if 'increase' button is selected again and another number from one to five is chosen, then that element should be increased.It's working, but all the numbers in the array are changed. And, when I hit the increase button again, the array is repopulated below the first price increases instead of only replacing the designated price.
'declare 5 element array of prices Dim prices() As Double = {12.2, 8.5, 12, 50, 2.4} Dim rateIncrease As Decimal Dim isConverted As Boolean
This is the code I am trying to run. I am just trying to increase a number in the excel file by "1" each time the button is clicked.

I'm currently making a email client, and currently this is a road block I have not been able to come over.

I am trying to create a program that has a button and a text box. Everytime the button is pushed I want it to add one to the text box. I keep getting this error: Overload resolution failed because no accessible 'Int' accepts this number of arguments?
Option Strict On

I have read just about every other post on this forum and many others, but they do not sort out the problem I have. I am building a website using asp in dreamweaver backed with an access database (this is what the company chose not me!)My page is a search page and is based on user input, my SQL query works as I have tested it both in access and through dreamweaver when setting up my dataset.Everything works, until I place a datagrid on my page to display the dataset results, then I get this error.

I haven't included all of the html as I don't see it being of any relevance to the error.
I'm trying to create a password change form for my company's vendors. There are a couple of scenarios I could encounter doing this:
1 - User enters invalid current password 2 - New passwords do not match 3 - User's account is locked 4 - User cannot authenticate because password is expired
It's case 4 that I'm struggling with, because their is no way for me to take the password the user entered and verify it against active directory without getting an error.
I have added a Split container onto my Form and within bottom Panel I have added a list box.How can I increase the size of the list box as I increase the size of the panel?
I've been using the FindWindow API for some time now, and it seems as if the function opts for an Windows Explorer window before any other window with the same window title.
For example, if you have a folder named Calulator open, along with the Calculator application built into Windows, FindWindow will return the handle to the folder every time.
I just thought this was an interesting occurrence, and I was wondering whether anyone knew if this is the case every time (an Explorer window over any other window) when using the FindWindow API.
I've been trying to use the FindWindowA api and also the FindWindowEx api in a little VB.NET 3.5 app and it doesn't appear to work. I get a positive long value returned whether I have an open window with the correct title or not. Anyone else noticed this?
Am trying to detect if a window is running, the result always returns a rather large number instead of 0 and I'm not sure why. All documentation I've read states this is right.
Private Declare Function FindWindow Lib "user32.dll" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long Dim ClassName As String = vbNullString Dim WindowName As String = "some fake window"
[code]....
but is there a way to search for a single process without using a For statement?
I just can't seem to get this right, what I'm trying to do is use FindWindow to find the windows of more than one window. Here is the code:
app_hwnd = FindWindow(vbNullString, CheckedListBox.CheckedItems)The thing is, if I use .SelectedItem, it only finds one window and if i use CheckedItems/SelectedItems it gives me an error: "Value of type 'System.Windows.Forms.ListBox.SelectedObjectCollection' cannot be converted to 'String'."
So right now, I'm confined to using FindWindow for only one window--when I want to do it for more than one window.
I'm using Visual Basic Express 2010 and SQL Express 2008 in Windows XP. At first I couldn't add a datasource (the .mdf file for the database) because of a "Operating system error 32" which I seemed to have resolved by giving myself full permissions for .mdf file (by right clicking on the file and going into properties and then Security) and restarting the SQL SERVER (SQLEXPRESS) service. The dataset for the database is in my solution explorer but when I right click on a table adapter to add a query and attempt to open up the query builder, I get the error in the title above.
Does anybody know what is the equivalent of findwindow or findwindex in vb.net. Here is what I am trying to do. I am reading a Real Time Adherence window that is dynamic(assumption) and is constantly refreshing. I have tried Findwindow and Findwindowex although I am able to get to the MDIclient and then to the window there is no "edit" field for me to read off. I have tried Spy++ and it also sees it but it does not have an available control for me to read the information.
I am developing an application that reads an MDI applications child window and grabs the information from a control such as a textbox or listbox. I have tried to use Findwindow in order to accomplish this. I have gotten all the way to the control, but once I get there it returns blank. Can anyone point me in the right direction to accomplish this.I am able to read the window title and get the control title but when I send a message to the window it returns 0. Now I am just experimenting so I have no concrete code, but here is a snippet.
I need to send two keys (" " and {Enter}) to a security warning in an Acrobat Window from a VB.NET application. Here is the function I use :
Private Sub SendAcroKey() Dim HWND As IntPtr HWND = FindWindow("Adobe Acrobat", vbNullString)
[Code]....
But I can't get FindWindow() to work properly, it always returns "0". I guess I'm not giving the good parameters, lpClassName and lpWindowName, but I dont now how to get the right ones. So here is the question : How can I know the lpClassName and lpWindowName of a security warning in Adobe Acrobat 7 professional ???
I really have to work this out but theres not much information on the web about those function, even on MSDN.
Public Class Form1 Private Shared Function FindWindow( _ ByVal lpClassName As String, _ ByVal lpWindowName As String) As IntPtr End Function '.... End Class
My question, what value should be passed into Function FindWindow(lpClassName, vbnullstring)? Can I use "Form1"?
I have spent the last 3 hours trying to figure this out with no success:The WIndows XP phone dialer has a "Hide Calls" available from the context menu, can someone run Spy++ (or similar) over it and let me know what message i should be looking out for to fire the "hide calls" option. Also, do i send it to the child ("Preview") or the parent ("Phone Dialer")
