I can finally filter my DataGridView every time a checkbox is checked or unchecked. However, I do not need it to filter out all of the messages each time a row is added, so I just need to check the current message. The following sub's demonstrate how I am doing this.
Public Sub FilterAllMessages()
'Show all rows
For Each showBand As DataGridViewBand In MessagesDataGridView.Rows
If showBand.Visible = False Then showBand.Visible = True
Next
[Code] .....
Great, they both work as intended...but I believe I am losing out on efficiency with the way I have this. I have tried adding another public sub CheckMessage() to run through the row, pretty much doing what each long list of If/ElseIf checks does.
IN the FilterLastMessage() I just call CheckMessage(), and in the FilterAllMessages() I call it like this:
For Each band As DataGridViewBand In MessagesDataGridView.Rows
CheckMessage()
Next
This isn't working as it is unable to get the index for each message when I have it FilterAllMessages(). I'm just wondering about making the 2 sub's above more efficient so I can have it CheckMessage() just once, instead of it doing basically the same thing twice. Also, the messages all go on to a DataGridView, and this will be constantly writing messages to the window. After a while I would imagine that this will bog down the program, so I am wanting to keep the number of messages that are displayed < 2000. How is the most efficient way to achieve this?
i want to filter date and also time (shortime) for example if Datum.hour="8:15" andalso Datum.day of week "Saturday"or "Monday" now i can only filter date ... this is my filterline objbindingsource.Filter = "Datum > = '" & Dtp1.Value.Date & "'"
The idea with this form is to add the futures which is calculated when the button is pushed but I need the list to update every time and show the values each time to which the previous value is added to the new calculation, e.g. of what it should look like in listbox:
Year 1: $1,290.93 Year 2: $2,724.32 Year 3: $4,350.76 etc....
I have been working on this a while and I am at a standstill, I was given a function to clear the form everytime it calculates but I don't know how to implement it, I am new to VB. Here is what I have so far:
Public Class frmFutureValue Private Sub btnCalculate_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles btnCalculate.Click
i have added a textbox to filter words out from my filename compare, any way i keep getting
Error1'txtComWords' is not a member of 'WindowsApplication1.Form1.StringSift3'.
Public Function PrepareWord(ByVal strWord As String, ByVal bDisRomTags As Boolean, ByVal bDisComWords As Boolean) As String Dim strToCheck As String = strWord If bDisRomTags Then
I have been working with the Outlook object library for 2007 and have been able to list all email in the Inbox. I can do the same with the Sent box but I do not see how to get the time it was sent. I have ReceivedTime for the In box but what about the Sent time?
I have the code below which works fine, however, if a mandatory field is not populated it prompts a message box, what I want to do is display ONLY one message box and show all the messages at one go, instead of one at a time. Also, I want the cursor to be prompting to the next mandatory field to be inserted according to the list.
there I am using a ToolTip on a Label that I am using as a place holder, so the same Label is being recreated over and over in diferent locations each time the ToolTip Message is diferent. The problem is the mesages is all showing ap at the same time overlaping one another.
I have added a column to a Datatable called CallsPerDay which is there to tell me how many telephone calls have been made on a particular day or days.Is there a datacolumn.expression which will allow me to Filter on the day, count the rows and then populate this added column with the result.
I have a DataGridView which I AllowUserToAddRows behavior enabled. I want to be able to force that only one row be added at time, then if the user clicks the save button the row is inserted into the database, and then another row may be added if the insert was successful.
The reason I want to do this is to get the last inserted id and insert that information into another table.
I have a form in which I add 9 labels in Run Time with .add method inside a panel. When I try to remove those labels in Run Time using For Each Loop, only 5 labels get removed. My code is given below.Code to Add Labels
While rs1.Read() channelid = rs1("s_id") Dim channelLabel As New Label[code].....
When i run the loop without .remove and .dispose it alerts .Text of all Lables present inside that Panel and With .remove and .dispose it does not remove all Lables and does not alert all .Text. In other words it misses 1 after 1.
I found that there was the Settings.Properties collection as well as the Settings.PropertyValues collection, and hopefully i'm not doing extra work here, but i'm creating both, and then assigning a value to the Settings(PropName).
Defaultly, in my "static" settings (through the IDE designer window and such) I have 9 settings/properties, and at run time when I'm processing, the Settings.Properties.Count doeos indeed equal 9.
Now, in the process of my application I generate some "saved" control properties myself, and actively "add" them to the Settings:
For Each prop As String In Me.Keys Try name = Layout & "." & _control.Name & "." & prop
[Code]....
This seems to work fine, and after the repetitive code (cycling through a collection) is finished, the Setting.Properties.Count does indeed equal 79, for the 70 new properties added.
I not only execute a My.Settings.Save() when the application exits, but I know I also have the SaveMySettingsOnExit set to true, but the next time i load up the app, my settings.properties.count is back to 9.

I have a data bound DataGridView. The final column of this is for the last change date to see how new the data is. I also have a hidden label on my form that has the current system time and date. I am wondering how do I take the date that is on the label and insert it into the column for the last change date on the datagridview when ever a new row is added. This way it automates the process of putting the exact time that row was added.
I'm having a problem with a MySQL query for returning the "last visit" field in a table.Originally I had:select fname, lname, last_visit from patient where isactive = 1 and uid = 1Which worked perfectly in MySQL, but as soon as the query is executed by my ASP.NET app, it adds in the time field also to the date area. So 2011-12-12 becomes 12/12/2011 12:00:00 AMI tried this also, with no improvement:
I want to ask a question about adding controls in design time (controls may be any win form control or a user control) and adding the control in run time.

I have found the documentation that allows me to change it in the config file, but I need to do it at runtime. What I am trying to acheive is to allow a beta tester to turn on more detailed logging (according to the TraceEventType...) when encountering an issue in order to email me the log. And then switch back to less detail.TraceEventType.Information)
Hi how's it going. In the middle of coding a banking application for a project. Part of it involves mortgage interest repayments. Was wondering if there was any way of logging the time a new record was created and added to the database and then adding interest to the balance owed periodically every 30 days..
In a VB.Net application, how can I either: Find the dropDownList selectedIndex position of something just added to a database.Have a form restart with the most recently-added entry showing in the DropDownList, by way of modifying the inline SQL query to display by date/time added
I am working on a project for a class, and am having trouble getting my program to automatically calculate the subtotal every time an item is added to the shopping cart list. I've tried sub procedures and functions, but I can't seem to get it to work.
I have a program that adds controls on the fly to an auto-scroll panel. When the panel is scrolled (viewing the bottom of the panel for example) and a control is added, it looks like it is added assuming the top left corner of the panel is still at 0,0 when in fact it may be 0,500. To see what I am talking about, create an empty "Windows Forms Application" project and insert the below code into it.
Friend WithEvents Panel1 As System.Windows.Forms.Panel Friend WithEvents btnAdd As System.Windows.Forms.Button Dim ButtonCount As Integer
i have multiple forms in a project and all have statusbar. there is no way to add textbox on status bar but in my previous thread i got the help to add the text box. i created a function in module so that i call that function from all the forms on load and add the textbox on status bar and also add the event on textchange. the function to be called on event change is in individual form (at present)[code]
