VB draws the icon to the form and encounters some problems, understand the pointers

Find a way to deal with it:

Check whether the filename is an empty string, if it is, do not perform the following operations.

for ii = 0 to 4

filename = getfromini("l" & ii, "Path", inipath)

if trim(filename)<>"" then

total = extracticon(, filename, -1)

Get the total number of icons.

for i = 0 to total - 1

p(i) = extracticon(, filename, i) 'Read each icon.

next i

drawicon , l(ii).left + 30, l(0).top - 50, p(0)

print filename

print ii

end if

next ii

getfromini("l" & ii, "Path", inipath)

Is the above a function that you wrote yourself? Does it encapsulate the API function of ini file operation?

If yes, your problem is"l"& ii here l string and ii is an integer. You should convert ii.

It seems that the function is inttochar(ii).

icon =

Replace this 1 with your icon number. However, it should be noted that this ** must be in regular ICO format, otherwise it cannot be used in the icon attribute.

pixels). The icons under XP are special, colorful and mostly 48*48. VB only supports 256-color icons, so if an icon does not contain ** in 256-color format, it cannot be used in VB.

2.You must use one of the form icons in the program. Specific steps:

Menu "Project" "xx properties", xx refers to the name of your project, click "Generate" item on the pop-up property window, find the drop-down list corresponding to "icon", the list is all forms, select one of them.

3.First, double-click on a form, if the properties window is open, then find the "icon" item in the properties window, click on it, you can see "..Click the button to open the file button, and select the icon you want.

If the properties window is not open, it can be opened here: menu "View" "Properties Window". Satisfied.

I would like to ask you where the icon is placed? If the icon is placed in a separate folder, you may not add the folder where the icon is located when compiling, and the program can still find the icon you want when you run it locally, but it will not work when you send it to others.

Landlord, you can use 16*16 24*24 32*32 charts.

Upstairs said that all the charts in the form will be changed, if only one or a few are changed, use the following method.

Modify the chart of form1:

private sub form_load()= loadpicture( +ico")end sub

2.Use the icon of the main form in the program, the specific method: first set the icon property of the main form, specify an icon file for it (the extension is ICO or CUR), note that VB does not support dynamic cursor (ANI) files, then click the "Project" menu, select "Project Properties", click the "Compilation" tab, select an icon for the main project, and use your main form on it.

3.Probably the same answer to the second question.

If it's VB6, it supports up to 24-bit true color ICO, you find a conversion tool to convert it.

1. All your ICO files are not standard ICO files, they may be disguised, such as a BMP, JPG or something, and directly change the suffix name or something. A normal ICO, VB would not have rejected it so ruthlessly. You can send me your icon with hi.

It is not a standard ICO file, the standard is 256 colors, 32*32

This must be a non-standard icon file.

Try it with Format Factory format conversion.

That's because the icon attribute doesn't directly support high color bits, and large sizes don't support it directly. You need to convert.

Size 48 Color 256 bits.

In VB6, the maximum bit depth of the icon attribute is 24, and 32-bit icons cannot be used.

Convert BMP to ICO in the following webpage to make the VB icon attribute.
