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
Ihave been looking for two days, and have not been able to place an msflexgrid or an mshflexgrid on my program. Any ideas what I must be missing? I am using vb in vs 2008 pro. Just building a simple windows form application
I just used MsFlex grid In my vb.net project. Its working in XP, but shot showing error in windows 7. error message like dll not found. But msflexgrid dll file included correctly.Still the same problem.
im currently developing a system. it's a tracking system and an alpha list..now currently im using datagrid to view thousands of records in foxpro free table in my vb form, how to export the datagrid into an excel for reporting but there is none..
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.
I am porting a vb6 application to VB.net. 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
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
When trying to edit an exisiting or trying to create a new dialog with a MSFlexGrid I get the following error The ActiveX control "Microsoft FlexGrid Control, version 6.0" could not be instantiated because it requires a design-time license.
Any one know how to get a "design-time license" for the MSFlexGrid control.
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?
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.)
so basically I have a text file that I read line by line now what I want is for each line to create a new picturebox with the image oww and on the text file, the lines contain image paths ok so after I get the images to show in a picturebox, I want each image to have a click event how can I do that
I'm trying to make an image fade in/out when the user hovers over the button. The fadein works when I enter the button but not when I leave it. How can I make this work?

If i add a picturebox in design then add an image who is triangle formed with transparent bg and make picturebox bg transparent in setting how do i then make an click event on the picturebox.image? iwant nothing happen if i click on the picturebox background only the image!
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.
I am developing a web sit using web parts in asp.net and c#. I have one problem, when i drag the web part from one web part zone to another, the image of the web part is still there at the web part zone, utill i drop it at the destination. i want to make that image of web part invisible at drag and drop time.
all this in datalist as you can see so it will be repeated..i have put one image in it now i want call a method when any image will be clicked i make one sub called s() in vb i want to call it i use on clientclick() event but doesn't work
Currently Im doing research on something that are related to graphical password.Can I know is that possible ASP.net(vb) can do such things.when mouse hover over a image, that image id will automatically save in database?Lets say that there are multiples images display in GridView. Only 2 images is the answer. So when user use mouse hover on those images, those images id that mouse hover will saved in database. Then, system will check 2 images id is in the list that mouse hover just now or not.
whats the quickest and least application hogging way to retrieve image from web and show in picturebox on listview selection event?
Heres the code i have already which produces app lag for abut 3-5 seconds per image loaded, i think as it stretches the image to fit into picturebox (which is needed)

I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?
Heres the tutorial with my new code encased in asterisks ...
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 selected).
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?
I'd like to verify if an image control has an image loaded . If it does , I want to unload that image (and load no image) , but if the image control has no image loaded , I want to load an image . Is it possible ?

The event handlers in my parent class are never called though the events are raised in the child class.

Eg. ""vb.net" 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?
I'm trying to execute different code depending on the button clicked (button 4 or 5) on Form1, but when I click on button5 to activitae the code on the Form2's Load event everything is Ok, but when I click the back button to return to Form 1 and click on the Button4 to activate the code on the Form2's Load event again, it doesn't active the Form's Load event, is there a way to form the form load event every time I access it from Form1? [code]
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
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.
I have a Visual Basic Program that, when I enter data into a textbox, uses LEAVE events to update it. However, it will not update until I go to another textbox or press a button or other similar control.This also happens when using the LOST FOCUS event.How can I make the textbox update (be it doing a financial recalculation or some other custom function) happen when the user clicks/tabs out of the textbox and NOT having to click on a button or into another textbox?Do you recommend having a separate button for performing the custom functions?
