How To Get Image From Vb6 MSFlexGrid OLEDragDrop Event

Jan 28, 2010

I have a VB project that is converted from VB6 to VB.NET.In this, I have a MSFlexGrid that is used as an interop compatibiliy. That means it is somewhat converted to .NET, but internally, many of the mechanisms are still from VB6/COM.I need to drag an image from a PictureBox (which is .NET) and drop it on the flexgrid.

This is what I do to initialize the drag:

Private Sub picStartSymbol_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles picStartSymbol.MouseDown
picStartSymbol.DoDragDrop(picStartSymbol.Image, DragDropEffects.Copy)
End Sub

Mar 3, 2012

i have a textbox,flexgrid and a button. this is my problem. when i input data in the textbox, the data will be added to the flexgrid using textmatrix. and if i click the command button. the data on the flexgrid will be registered to the sql table.however, if there's two or more data (different data) on the flexgrid. the data will be registered to the mysql but the data is same with each other.

the input is :

1st row: (3500)
2nd row: (2000)
3rd row: (1000)

but the output (in the sql table) is this.

1st row: (3500)
2nd row: (3500)
3rd row: (3500)

this is my code in the command button.conn.Execute "INSERT INTO tbl_purchaseDetails(Quantity) VALUES('" & gridpr.TextMatrix(gridpr.RowSel, 0) & "')"..BTW i am using navicat to connect my sql.

Datagridview - Porting A VB6 Application With Msflexgrid

Mar 17, 2009

I am porting a vb6 application to One of the key forms has a large msflexgrid on it - about a 1000 columns and 50 rows. It has 2 header rows - the first header row has merged cells to form a main header and the second row has sub headings. There is no requirement for any data entry and it's unbound. The code does the work in deciding what to display (if anything) in each cell. It is solely used to display data in the form of a character and a coloured background and to display a tooltip text with more information when you mouse over it. Works beautifully in vb6. I'm trying to decide whether to:

a) use the vb6 msflexgrid in the .net version
b) use the datagridview - which at a first glance seems to have a problem merging the cells on the header row
c) build my own custom control to do the job

Insert Data From MSFLEXGRID Into MS Word?

Mar 2, 2010

I am using the following code and I am able to create a new WORD Document and create a Table inside it and insert data into it sucessfully from a MSFLEXGRID (just like a datagrid) on my form. I would appreciate if anyone could tell me how to achieve the same but by inserting the data into a specific document saved as ("c:123.doc") with a table already created inside it.

I just don't want to create a new word file everytime and then create a table and then do the insert.I want to keep my 123.doc with a formatted table inside it and all i need is to insert data from the Grid into it.

Dim oWord As Object
Dim oDoc As Object
Dim oTable As Object
Dim oSelection As Object

Restore Scrolling Position After A MSFlexGrid Reload?

May 12, 2012

I have a fixed-size pane for displaying MSFlexGrid rows, and, when the number of rows exceeds the pane capacity, a vertical scroll bar is displayed. If the user scolls downward, and selects a lower row for action, I want the display to be restored (approximately) after the grid is reloaded.row selection is maintained explicitly by code: If the action is a change in row data, the successor row will be selected (by code); if the action is row deletion, the preceeding row will be selected (by code). Since the grid must be reloaded following the change, MSFlexGrid will present the first n rows by default. (The grid must be reloaded because the actions may have affected the presentation order.)How can I force a scrolling repositioning after a grid reload? In my imagination I see a sequence somewhat like make-non-visible, reload-grid, set-scroll-position, make-visible, set-new-row-selection. Is something like this easily done?

Set Column Width In MSFlexGrid (Studio 20008)?

Mar 10, 2012

I'm at the Studio 2008 stage in migrating from VB6 to Studio 2010. My application appears to run OK for the most part, but my MSFlexGrid display's single column is just 8 or 10 characters wide -- it should span the entire grid display (i.e., have the same width as the grid).The Studio 2008-Upgraded code sets several grid properties correctly, but the statement ".ColWidth(0) = .Width" (in the scope of a With block) causes an error. So does the statement ".TextMatrix(0, 0) = string".

Not only are these properties not included in the upgraded control (now identified as AxMSFlexGrid), but some column-related properties are greyed out in the properties list. My grid size was set originally by cursor drag, and the present .Size sub-properties of .Width and .Height are set to the numbers 593 and 329, respectively. (My form has a fixed size and is user-moveable but not user resizable.)

Assigning Event Handler To TabControl's Image (No OwnerDraw)

May 27, 2012

Is it possible to assign the MouseDown event handler or equivalent to an image (from ImageList) of a tabcontrol without using OwnerDraw?  I can add images to tabs through ImageList.  And I can draw something that looks like a close button on each tab, using OwnerDraw.  But I notice that the tab sizes will be fixed regardless of the tab labels.  I want the tab sizes to be flexible with the labels.  For now, the second best alternative to assign events to tabs seems to be use of contextual menus.  But it's true that some people just don't want to right-button-click on tabs.And I have seen a project where somebody uses a 32-bit library declare. And I can't use it because I only develop 64-bit apps.

Override An Event - TextChanged Event Not To Be Triggered When The CellClick Event Occurs?

Jul 20, 2010

I'm trying to validate a few things in a form I'm building. It has a datagrid with clients info (taken from an access database) and a few textboxes where the user can type some search criteria. The thing is that those same textboxes are used to add new clients to the database and to modify a client's information if one from the datagrid is selected, so I made it that the buttons to insert and modify clients are disabled on load and thenevery time the text on a textbox changes ("TextChanged" event) they become enabled. So far so good. But then I wanted to make it so when a client from the datagrid is selected both buttons become disabled again until the text on a textbox changes (to make sure they're adding a different client and not the same one that was

I tried using the CellClick event from the datagrid to disable the buttons, but since every time a client is selected from the datagrid the info is shown on the textboxes, this triggers the TextChanged event too, and the buttons become available.So, is there a way I can tell the TextChanged event not to be triggered when the CellClick event occurs?

[Timer] Trigger Event Manually - User Must Wait For A Minute Before The Event Is Triggered

Feb 12, 2010

Eg. """ timer event trigger on purpose". This application is meant to run at all times to download a web page every minute. To avoid freezing the UI, I read that the best solution is to move the code from a While/Sleep loop to a Timer that will be triggered every minute. The problem I have, is that the user must wait for a minute before the event is triggered:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Interval = 60000
Timer1.Enabled = True


Is it possible to force this event to occur instead of waiting for it?

Make Sure 'ProgressChanged' Event Executes Completely Before Executing 'RunWorkerCompleted' Event Of Background Worker

Sep 20, 2010

Starting from my understanding about Background worker control, I understands that the background worker runs the code in its "DoWork" method in a seperate thread, while ProgressChanged and RunWorkerCompleted events are executed on the main thread.In my senerio, I report the progress and under an specail condition my application displays a message box to the user in "ProgressChanged" method using MessageBox.Show(). and in "Run Worker Completed" event the application finalize some work. There the sequence is important, suppose that the message is of Yes or No type and finalization depends on it. Now when i run my application, the background worker triggers "ProgressChanged", but as soon as backgroundWorker's cancelAsync() is called the program leaves the current "ProgressChanged" method and executes "RunWorkerCompleted" code first.How can i make sure that the "Run Worker Completed" code executes only after the completion of ProgressChanged method.

As you noticed, in the code bellow, the event argument for the form click event has the type "TimedEventArgument".When the event is raised, e.Time holds the time where the form was clicked.Add the missing code in the class Form1 to make this work.You will not change anything to the methods "Form1_Click" or "Form1.Load".You will not use Option Strict On.  HOWEVER, you will not do any narrowing or late binding that wouldn't have been allowed if Option Strict was on.You cannot create any new Class, Structure or Module.You cannot cast the EventArgs to TimedEventArg in any way

Get Information About A Processes When An System Process Event Is Raised An Event

May 17, 2012

I am making a function of an application that when a function is called the application will close all processes that are owned by the user and were started after a specific point. My thoughts on this would be to trigger an event in my application every time a process is started and ended, and only if the processes is owned by the user, the event should get information (e.g. the process ID, name, etc) about that process and add or remove that information to/from an array depending on if the process starts or ends. Then when a function is called end all the processes in that array.
